Early Middle Japanese (中古日本語, Chūko-Nihongo)[1] is a stage of the Japanese language between 794 and 1185, which is known as the Heian period (平安時代). The successor to Old Japanese (上代日本語), it is also known as Late Old Japanese. However, the term "Early Middle Japanese" is preferred, as it is closer to Late Middle Japanese (中世日本語, after 1185) than to Old Japanese (before 794).

Background

[edit]

Old Japanese had borrowed and adapted the Chinese script to write Japanese. In Early Middle Japanese, two new scripts emerged: the kana scripts hiragana and katakana. That development simplified writing and brought about a new age in literature, with many classics such as The Tale of Genji, The Tale of the Bamboo Cutter, and The Tales of Ise.

Writing system

[edit]

Early Middle Japanese was written in three different ways. It was first recorded in Man'yōgana (万葉仮名), literally "ten thousand leaves borrowed labels", in reference to the Man'yōshū poetry anthology and the "borrowing" of the kanji characters as "labels" for the sounds of Japanese. Certain Chinese characters were borrowed to phonetically spell out Japanese sounds. Cursive handwriting gradually gave rise to the hiragana (平仮名, "flat/simple borrowed labels") and Buddhist shorthand practices of using pieces of kanji to denote the sounds then developed into the katakana (片仮名, "partial/piece borrowed labels").

It is worth noting that the man'yōgana in each cell only indicates one of many contemporary options for spelling each Japanese mora – in the table above, each chosen character is the direct origin of the corresponding modern hiragana. See also Hentaigana for a fuller description of how multiple hiragana could be used to spell a single sound. Also note that hiragana forms were not standardized at that time.[2]

Although man'yōgana specify different kanji to represent voiced phonemes versus unvoiced phonemes, it is not until the Meiji period that we see standardized usage of the dakuten diacritic ゛ to explicitly mark voicing for hiragana and katakana.

Japan officially adopted simplified shinjitai (新字体, "new character forms") in 1946 as part of a round of orthographic reforms intended to improve literacy rates. The so-called kyūjitai (旧字体, "old character forms") are equivalent to Traditional Chinese characters, and these forms were the ones used in historical man'yōgana. Modern transcriptions of classical texts are predominantly written in shinjitai. To avoid unnecessary ambiguity, quotes from classical texts would be written in kyūjitai.

Additionally, there are many spelling differences between Modern Japanese and Early Middle Japanese even for the same word. For example, 万葉集 is spelled in modern Japanese hiragana as まんようしゅう (man'yōshū), while in Early Middle Japanese, this would have been まんえふしふ (man'yefushifu). Details on these spelling rules are helpful for understanding historical kana usage.

Phonology

[edit]

Developments

[edit]

Major phonological changes were characteristic of the period.

The most prominent difference was the loss of certain spelling distinctions found in the Jōdai Tokushu Kanazukai ("Ancient Special Kana Usage"), which distinguished two types of /i/, /e/, and /o/. While these distinctions had begun to blur already at the end of the Old Japanese stage, they were completely lost in Early Middle Japanese. The final distinction to be lost was /ko1, go1/ vs. /ko2, go2/.[3] For example, around the year 800 in very early Early Middle Japanese, in the same text /ko1/ was still represented by cursive 「古」, while /ko2/ was represented by cursive 「己」.[4]

In the 10th century, /e/ and /je/ progressively merged into /je/, and /o/ and /wo/ had merged into /wo/ by the 11th century.[5][6][7]

An increase in Chinese loanwords had a number of phonological effects:

The development of the uvular nasal and geminated consonants occurred late in the Heian period and brought about the introduction of closed syllables (CVC).[10]

Phonetic realization

[edit]

Theories for the realization of /s, z/ include [s, z], [ts, dz], and [ɕ, ʑ]. It may have varied depending on the following vowel, as in Modern Japanese.[citation needed]

/ɸ/
[edit]

By the 11th century, /ɸ/ had merged with /w/ between vowels.[11]

Grammar

[edit]

Syntactically, Early Middle Japanese was a subject-object-verb language with a topic-comment structure. Morphologically, it was an agglutinative language.

Phrase

[edit]

A paragraph of Early Middle Japanese can be divided into the following units from large to small.

  • Sentence (文(ぶん)) ：A series of meaningful words divided from a paragraph by 「。」(period).
今(いま)は昔(むかし)、竹(たけ)取(とり)の翁(おきな)といふ者(もの)ありけり。
(from The Tale of the Bamboo Cutter)
Romanization: ima fa mukasi, taketori no okina to ifu mono arikeri.
Modern Japanese translation：今からみるともう昔のことだが、竹取の翁という者がいた。
English translation: Long before the present, it is said that there was someone called Old Man Bamboo Cutter.
The noun「昔(むかし)」("long past") is actually a predicate (means "is long past"). The predicate is not necessarily a verb in Early Middle Japanese.
  • Phrase (文(ぶん)節(せつ)): The smallest unit naturally divided from the rest of a sentence by its meaning.
今は
昔
、
竹取の
翁と
いふ
者
ありけり
。
The function of the auxiliary particle「は」is to highlight the noun「今」(now), which cannot be separately explained, so they should be in the same phrase. Similarly, the particle 「の 」 represents the relation between the modifier「竹取」("bamboo cutter", a compound noun) and the modified noun 「翁」(old man), like the preposition "of". Additionally, the particle 「と」 connects the called name 「翁」(modified by 「竹取」) to the verb「いふ」( "call"), just like a preposition. As for the auxiliary verb「けり」, it further clarifies that what the verb「あり」 ("be, exist") describes is a rumor about the past, but not a direct experience (i.e. 間(かん)接(せつ)過(か)去(こ)), so it should be included in the same phrase as 「あり」. In contrast, even if the verb 「いふ」 does modify the noun「者」 ("someone"), its meaning can still be realized naturally without any help from other words.
  • Word (単(たん)語(ご)): The smallest grammatical unit.
今
は
昔
、
竹取
の
翁
と
いふ
者
あり
けり
。
Although 「竹取」is a combination of the noun 「竹(たけ)」and the verb 「取(と)り」("get", infinitive), any compound noun, verb, or adjective should be considered as a single grammatical unit.

Classes of words

[edit]

Words were classified as follows:

  • Cannot stand alone as a phrase
    • (Auxiliary) particle (助(じょ) 詞(し)): Without inflection. Has various functions like emphasis, acting like a postposition, hinting about the subject or expressing interrogative mood.
    • Auxiliary verb (助(じょ)動(どう) 詞(し)): With inflection. Describes additional information of Yougen like tense, aspect, mood, voice, and polarity. Alternate descriptions include grammaticalized verb or Verb-like ending.
  • Can stand alone as phrase
    • Without inflection
      • Cannot be subject
        • Adverb(副(ふく) 詞(し)): mainly modifies Yougen.
        • Conjunction (接(せつ)続(ぞく)詞(し))
        • Interjection (感(かん)動(どう)詞(し))
        • Rentaisi (連(れん)体(たい)詞(し)): mainly modifies Taigen.
      • Can be subject: Taigen (体(たい)言(げん), the words that are the main body of the sentence)
        • Noun (名(めい) 詞(し))
        • Pronoun (代(だい) 名(めい) 詞(し))
        • Number (数(すう) 詞(し))
    • With inflection: Yougen (用(よう)言(げん), the words to predicate or to "use" other words)
      • Verb (動(どう) 詞(し))
      • Adjective (形(けい)容(よう) 詞(し)): actually the stative verbs.
      • Adjective verb (形(けい)容(よう)動(どう) 詞(し)): a different kind of "adjective", which is derived from a noun. Hence also referred to as adjectival noun in English.

Auxiliary particle

[edit]

(Auxiliary) Particles had various functions, and they can be classified as follows:

Class of particle Functions Example

(Particle is labeled in red.)

Case particles
格(かく)助(じょ)詞(し) 		indicating the relationship between a phrase and its following phrase.

(i.e. not limited to nouns, so slightly differs from "case" in English)

いづ
方(かた)へか
罷(まか)りぬる
(The Tale of Genji)
In which direction of escape has gone (the bird)?

(The verb 「罷る」 is the polite form, i.e.「丁寧語」, of the verb 「行(い)く」"go")

Conjunctive particles
接(せつ)続(ぞく)助(じょ)詞(し) 		indicating the relationship between clauses. 文(ふみ)を書(か)きてやれども返(かへ)り事(こと)もせず。(The Tale of the Bamboo Cutter)
Even though「文を書きてやれ」, but 「返り事もせず」.
(「ども」has to be preceded by the realis mood, e.g.,「やれ」is the realis mood of the verb「やる」,

to express the appropriate meaning.)

Adverbial particles
副(ふく)助(じょ)詞(し) 		mainly modifying its following yougen. ただ浪の白(しろ)きのみぞ見(み)ゆる (Tosa Nikki)
...can only see (exactly) the white wave (actually, 「のみ」 limits the expressive range of 「見ゆる」)
(The verb 「見ゆ」is "bound" by the binding particle 「ぞ」, so it occurs in the attributive form「見ゆる」.)
Binding particles
係(かかり)助(じょ)詞(し) 		emphasizing its phrase or making it interrogative, and limiting the inflection

form of the ending yougen or auxiliary verb.

いづ
方へか
罷りぬる

In which direction of escape has gone (the bird)?
(The perfect auxiliary verb「ぬ」is "bound" by the binding particle 「か」, so it occurs in the attributive form 「ぬる」.)
Final particles
終(しゅ)助(じょ)詞(し) 		mainly at the end of sentence, indicating many kinds of moods

(e.g. interrogative mood, emotive assertion)

我(われ)はこの比(ごろ)惡(わろ)きぞかし(Sarashina Nikki)
At that time I'm definitely not good!
(Although the binding particle 「ぞ」 is at the end of sentence, it still requires its preceding words to be attributive.)
Interjectory particles
間(かん)投(とう)助(じょ)詞(し) 		similar to final particle, but occurs more freely, and is often

used as a short stop between sentences.

朝(あ)臣(そん)や。さやうの落(お)ち葉(ば)をだに拾(ひろ)へ (The Tale of Genji)
(Yugiri) Ason! At least pick these kinds of falling leaves up!

Case particle

[edit]
  • 「が」 (ga) and 「の」 (no) : "of, ...'s". It hints the present of subject, relation of modification between phrases or nouns.
  • 「を」(wo) (accusative). Optional.
  • 「に」(ni) (dative/locative). It had a wide range of functions ('to' or 'for' a person; 'by' an agent'; 'at' or 'to' a place; 'at' a time), and in some uses, especially when indicating time, it was optional.
  • 「より」(yori) (ablative).
  • 「まで」(made) (terminative: 'until'; 'as far as').
  • 「と」(to) (comitative: 'with'; essive 'as').
  • 「へ」(fe) (allative: 'to'). 「へ」 was derived from the noun「 邊(へ)」'vicinity; direction', which 「わ」 occasionally found in the location noun structure Noun + 「の」 + Location Noun to mean 'near', or in the noun-deriving suffix 「べ」 (< 「のへ」) in such words as 水(みづ)べ 'beside the water' .

The nominative function was marked by the absence of a particle in main clauses and by the genitive particles in subordinate clauses. The dative/locative particle -ni was homophonous with the simple infinitive form of the copula -ni, with verbal suffixes supplies more complex case markers -ni-te ('at' a place) and -ni si-te or -ni-te ('by means of'). A number of particle + verb + -te sequences provided other case functions: -ni yori-te 'due to' (from yor- 'depend'), -ni tuki-te 'about, concerning' (from tuk- 'be attached'), and -to si-te 'as' (from se- 'do'). More complex structures were derived from genitive particle + Location Noun + appropriate case particle (typically locative -ni) and were used particularly to express spatial and temporal relations. Major location nouns were mafe 'front' (Noun-no mafe-ni 'in front of Noun'), ufe 'top' (Noun-no ufe-ni 'on top of Noun' ~ 'above Noun'), sita 'under' (Noun-no sita-ni 'under Noun), saki 'ahead' (Noun-no saki-ni 'ahead of Noun)', etc.

Conjunctive particle

[edit]
  • Infinitive + 「て」(te): 'and (then/so), when, because'. It usually expressed a close sequential link between the predicates that it connects. The subjects of the two verbs connected by「て」 were usually the same.
  • Realis + 「ば」(ba): 'and (then/so), when, because'. It usually expressed a looser sequential link between the predicates that it connected. The subject of both verbs connected by 「ば」 was usually different.
  • Irrealis + 「ば」(ba): 'if...', It usually expressed an unreal condition.
  • Irrealis + 「で」(de):[12] negative 'and', 'without ... ing', 'rather than ... ', derived from old infinitive of negative auxiliary verb「ず」(i.e. 「に」) + the particle 「て」with sound change.
  • Various forms + 「と/とも」 (do / domo): 'even if, even though'. Most yougens and auxiliary verbs took the conclusive form, bigrade verbs take the infinitive in earlier texts, r-irregular verbs took the attributive form, and some auxiliary verbs inflecting like adjective and negative auxiliary verbs「ず」also took the attributive.
  • Infinitive + 「つつ」 (tutu): 'while (at the same time)'.
  • Infinitive of verb / stem of adjective + 「ながら」(nagara): 'while, while still' or 'despite'.

Binding particle

[edit]

There were some special particles that limited the inflectional form of the yougen and auxiliary verb at the end of a sentence. These particles are called binding particles(係(かかり)助(じょ)詞(し)). These limitations are called binding rules(係(かか)り結(むす)びの法(ほう)則(そく)).

Binding particle Meaning Ending form Example
ぞ emphasis on its phrase attributive ふるさとは花ぞ昔(むかし)の香(かおり)に匂(にほ)ひける (Kokin Wakashū, 42th)

In (my) hometown, the flowers (still) smell exactly like the scent of the past!

attributive of「けり」(Auxiliary verb of emotive assertion)

なむ その竹の中に、もと光る竹(たけ)なむ一(ひと)筋(すぢ)ありける (The Tale of the Bamboo Cutter)

Among these bamboos, there was one bamboo that was shining at root.

(However, note that there's no relative pronoun in Japanese even in old times)

attributive of「けり」(Auxiliary verb of the past)

や(やは) question, or rhetorical question 春(はる)やとき花やおそきと聞きわかむ　(Kokin Wakashū, 10th)

I listen (to the singing of the nightingale) and try to realize. Is spring too early or the flower (blooming) too late?

attributive of adjectives「疾(と)し」("early, fast") and「遲(おそ)し」 ("late, slow")

か(かは) 生きとし生けるもの　いづれか歌を詠(よ)まざりける　(Kokin Wakashū, Kana preface)

(Among all) living beings, who doesn't write a poem!(or ?)

attributive of「けり」

こそ strong emphasis on its phrase realis 男はこの女をこそ得(え)めと思ふ　(The Tales of Ise)

(However) the man thought he must get (married with) that girl.

realis of modal auxiliary verb「む」

Note that the case particle「と」indicates a preceding quote, and a quote should be considered as an independent sentence when applying the binding rule.

Susumu Ōno assumed that these binding particles were originally final particles.[13] For example:

Man'yōgana: 苦毛 零來雨可 (from Man'yōshū, 265th)

Modern transliteration: 苦(くる)しくも　降(ふ)り来(く)る雨(あめ)か

Translation: How miserable! Why it starts to rain!

Notice that 「来る」 is attributive(the modification to the noun 「雨」). According to his assumption, if we want to emphasize the noun 「雨」, we can invert the whole sentence as the following:

雨か降り来る

Obviously, this gives birth to the binding rule. Since other binding particles can also be considered as final particles in Old Japanese, this assumption is reasonable.

Verbs

[edit]

Early Middle Japanese verb inflection was agglutinative. Most verbs were conjugated in 6 forms and could be combined with auxiliary verbs to express tense, aspect, mood, voice, and polarity. Several of the auxiliary verbs could be combined in a string, and each component determined the choice of form of the preceding component.

In Japanese there are many different yougens with the same pronunciation, or the same yougen has various meanings. To distinguish, modern transliteration uses Kanji to highlight these differences. For example, the lower bigrade verbs「慣(な)る」means "get used to", but its also means "become familiar" which is represented by「馴(な)る」. Meanwhile, the quadrigrade verb「成(な)る」has the same pronunciation with 「慣(な)る」but it actually means "become".

Conjugation

[edit]

Early Middle Japanese inherited all eight verbal conjugations class from Old Japanese and added new one: Lower Monograde, but there's only 「蹴(け)る」("kick by foot") classified as Lower Monograde in Early Middle Japanese.

Early Middle Japanese Verbs were divided into 5 class of regular conjugations:

Quadrigrade (四段, yodan), Upper monograde (上一段, kami ichidan), Lower monograde (下一段, shimo ichidan), Upper bigrade (上二段, kami nidan), Lower bigrade (下二段, shimo nidan).

There were also 4 "irregular" (変格) conjugations:

K-irregular (カ変, kahen), S-irregular (サ変, sahen), N-irregular (ナ変, nahen), R-irregular (ラ変, rahen).

The conjugation of each is divided into 6 Inflectional forms(活(かつ)用(よう)形(けい)):

  • Irrealis (未然形, mizenkei, "imperfect form")
  • Infinitive (連用形, ren'yōkei, "form linking to Yougen")
  • Conclusive (終止形, shūshikei, "form to end [a sentence]")
  • Attributive (連体形, rentaikei, "form linking to Taigen")
  • Realis (已然形, izenkei, "perfect form")
  • Imperative (命令形, meireikei,"form to give order")

The English names for the irrealis and the realis differ from author to author, including negative and evidential, or imperfective and perfective.

In following table, red part means stem, while blue part means Inflectional suffix.

  • Inflectional form = (stem) + Inflectional suffix (活(かつ)用(よう)形(けい) = 語(ご)幹(かん) + 活用語(ご)尾(び))
  • Inflectional suffix = root consonant + real suffix (root consonant is unique to every verb.)

Upper Bigrade
上二段 		過(す) すぎ (-i) すぐ (-u) すぐる (-uru) すぐれ (-ure) すぎよ (-iyo) 'pass'
Lower Bigrade
下二段 		受(う) うけ (-e) うく (-u) うくる (-uru) うくれ (-ure) うけよ (-e[yo]) 'receive'
K-irregular
カ変 		- こ (-o) き (-i) 来(く) (-u) くる (-uru) くれ (-ure) こ (-o) 'come'
S-irregular
サ変 		- せ (-e) し (-i) 爲(す) (-u) する (-uru) すれ (-ure) せよ (-e[yo]) 'do'
期(き) きせ きし きす きする きすれ きせよ 'set the date' *
N-irregular
ナ変 		死(し) しな (-a) しに (-i) しぬ (-u) しぬる (-uru) しぬれ (-ure) しね (-e) 'die'
R-irregular
ラ変 		有(あ) あら (-a) あり (-i) ある (-u) あれ (-e) 'be, exist'

*Noted that most S-irregular is the combination of a noun and 「爲(す)」, for example, 「期(き)す」 is a combination of the noun 「期(き)」 ('date') and 「爲(す)」.

The 「よ」 at the end of the imperative forms is optional, although exceedingly common.

The system of 9 conjugation classes appears to be complex. However, all nine conjugations can be subsumed into variations of two groups:

  • the consonant-root verbs (quadrigrade, N-irregular and R-irregular verbs)
  • the vowel-root verbs (others)

The irregularity of N-irregular verbs occurred only in the conclusive and the attributive, and as there are no quadrigrade verbs with n-roots, quadrigrade and N-irregular verb patterns may be treated as being in complementary distribution.[14] Vowel-root verbs consist of bigrade verbs (the majority), a few monograde verbs (especially 見(み)る 'see' and 居(ゐ)る 'sit'), the K-irregular verb 来(く) 'come', and the S-irregular verb se- 'do' (or -ze- in some compounds).[15] The difference between 'upper' and 'lower' bigrade or monograde verbs is whether the vowel at the end of the root was i or e. The difference between bigrade and monograde was whether in the conclusive, attributive, and realis, the initial u of the ending elided the vowel of the root or the vowel of the roots elides the initial u of the ending.

There are some questions about this arrangement of forms:[16]

  • The irrealis is not used as an independent verb form: it must be followed by an auxiliary.
    That said, there is a limited set of nouns appearing in Old Japanese and ending in -a, that appear to overlap phonetically and semantically with the irrealis form of certain verbs. These could be analyzed as resultative deverbal nouns.
  • The classical passive auxiliary verb 「る」 (「ゆ」in Old Japanese) attaches to the irrealis stem with an -a ending (i.e. quadrigrade, N-irregular and R-irregular), while the other classical passive auxiliary 「らる」 (「らゆ」in Old Japanese) attaches to the irrealis stem without an -a ending (i.e. for the bigrade verbs, whose stems end in either -e or -i). This raises the assumption that this -a ending appears to be part of the auxiliary verb, but not part of the verb conjugation stem. (The causative auxiliary verbs 「す」 and 「さす」have same distribution and vowel arrangement.) According to this assumption, some scholars like Nicolas Tranter argue that the irrealis does not exist, per se, interpreting this instead as a more primitive "stem" plus an -a element that is the start of a following word. However, this rejection of the irrealis cannot explain the attested forms seen where the irrealis stem ending in -a is followed by the conditional particle 「ば」("if"), expressing an unreal condition (i.e. subjunctive mood) in classical Japanese.[17] In actuality, the Japanese term 「未然形」 (mizenkei), while often translated as "irrealis", literally means "imperfect form", and it is named after this kind of usage. Additionally, the rejection cannot explain the modal auxiliary verb 「む」("seems as if, looks like, as though it should/could..."), which also attaches to the irrealis.[18] Various examples:
Quadrigrade verb: 物(もの)に襲(おそ)はるる心(ここ)地(ち)して (The Tale of Genji)
Quadrigrade verb: 名(な)にし負(お)はばいざ言(こと)問(と)はむ (Kokin Wakashū, 411th)
Lower Bigrade: 舅(しうと)に譽(ほ)めらるる婿(むこ) (The Pillow Book)
K-irregular: 月(つき)の都(みやこ)の人(ひと)まうで来(こ)ば捕(と)らへさせむ (The Tale of the Bamboo Cutter)
Note that auxiliary verbs have their own inflections. For example, 「るる」 is the attributive of passive / spontaneous / potential auxiliary 「る」, while「らるる」 is the attributive of synonymous 「らる」 (the form attaching to bigrade verbs, whose stems end in vowels -e or -i). Additionally, both of these auxiliaries inflect according to the lower bigrade conjugation paradigm.
  • The infinitive had two functions: a linking function with another yougen or auxiliary verb, and a nominal function as a deverbal noun, but these two functions have different pitch patterns.
  • Generally, The yougen or auxiliary verb occurred before conjunction particle 「とも」 ("even if") in the conclusive form, but in some instances in Old Japanese poetry, the upper monograde verb 「見(み)る」 appears in the infinitive form instead before「とも」:[19]

Man'yōgana: 之婆之婆美等母 安加無伎禰加毛 (Man'yōshū, 4503th)

Modern transliteration: しばしば見(み)とも、飽(あ)かむ君(きみ)かも

It is possible that the monograde verb infinitive form mi above that was used before 「とも」 was the earlier true conclusive form. Alternatively, the form above may have been an instance of poetic contraction to limit the number of morae on the line to the expected seven.

  • Additionally, before auxiliary verb 「べし」(beshi, "should/could"), any yougen should generally use the conclusive, while R-irregular verbs use the attributive instead (「あり」 ari, 'be' at the end of a sentence but 「あるべし」 aru beshi, 'should be').[20] With endings such as 「べし」 (beshi), there is strong evidence that this word was originally the adverb 「宜(うべ)し」 (ubeshi, "certainly"),[21] and thus the observed combination of aru beshi is probably a fusion of the root ar- of the verb with the initial u sound of the auxiliary — suggesting that, in 「あるべし」 (aru beshi), when we would expect ari beshi, the apparently anomalous u was actually part of the following word, and not part of the verb form.

Auxiliary verbs

[edit]

Auxiliary verbs are attached to the various forms of yougen, and a yougen could be followed by several such endings in a string. Auxiliary verbs are classified into many inflectional class like verbs.

Generally, to learn how to use an Auxiliary verb, we need to know (1)its inflection, (2)required forms of its preceding word, and (3) various function. The following is a detail example about 「る」and 「らる」.

「る」 requires to be preceded by irrealis with -a ending (i.e. quadrigrade, N-irregular and R-irregular), while 「らる」requires irrealis without -a ending(i.e. other classes).

They have 4 different functions.

  1. Representing passive mood:
    人(ひと)にあなづらるるもの (The Pillow Book)
    translation: thing that is despised by people
  2. Representing slight respect to someone (by means of passive mood):
    母の悲(かな)しがらるること (Tosa Nikki)
    translation: the thing that make the mother (author's wife) sad (i.e. representing slight respect to his own wife)
  3. Expressing possibility or potential.
    弓(ゆみ)矢(や)して射(い)られじ (The Tale of the Bamboo Cutter)
    translation: It doesn't seem bow and arrow can shoot (it down). (Noted that 「じ」is a modal auxiliary verb that requires to be preceded by irrealis)
  4. Representing a spontaneous voice(i.e. without volitional control).
    風(かぜ)の音(おと)にぞ驚(おどろ)かれぬる (Kokin Wakashū, 169th)
    translation: the sound of wind (exactly) has made me startled.
    (Noted that「ぬる」is attributive of perfect auxiliary verb「ぬ」. Since it's "bound" by binding particle「ぞ」, it has to occur as attributive.)

Rough classification

[edit]

Voice: 'passive' and 'causative':

  • Consonant-stem verbs + 「る」, vowel-stem verbs + 「らる」 (lower bigrade): passive voice; spontaneous voice (expressing lack of volitional control); honorific; potential ('can').
  • Consonant-stem verbs + 「す」, vowel-stem verbs + 「さす」 (lower bigrade): causative; honorific.
  • Any verb + 「しむ」 (lower bigrade): causative; honorific. It often occurs in Kanbun.

Tense/Aspect:[22][23]

  • Irrealis +「り」 (R-irregular): progressive or perfect aspect. Only attached to quadrigrade or S-irregular verbs.
  • Infinitive + 「たり」 (R-irregular): progressive or perfect aspect. Attached to any verbs.
  • Infinitive + 「ぬ」 (N-irregular): perfective aspect.
  • Infinitive + 「つ」 (lower bigrade): perfective aspect.
  • Infinitive + 「き」(unique conjugation): witnessed past tense.
  • Infinitive + 「けり」 (R-irregular): unwitnessed past tense, or emotive assertion.
  • Irrealis + 「まし」 (unique conjugation): counterfactual ('would have ... ed'). The combination 「ましかば」(Irrealis + ば) expresses a counterfactual condition ('if ... had ... ed').

Mood:[22][24]

  • 「む」 (quadrigrade): tentative mood, expressing among other functions uncertainty ('maybe', 'shall I?'), intention ('I shall'), and hortative ('let's').
  • 「べし」 (siku-adjective): debitive mood, expressing 'can', 'should', or 'must'.
  • 「なり」 (R-irregular): hearsay mood.

Polarity:[25]

  • 「ず」(unique conjugation): negative.
  • 「じ」 (uninflected): negative of the tentative mood (not seem...).
  • 「まじ」(siku-adjective): negative of the dubitative mood.

Adjectives

[edit]

There were two types of adjectives: regular adjectives and adjectival nouns.

The regular adjective was subdivided into two types: those for which the adverbial form ended in 「-く」(-ku) and those that ended in 「-しく」(-siku).

They usually had 「-じ」 rather than 「-じき」 in its attributive form.

The -kar- and -sikar- forms (カリ活用) were derived from the verb 「有(あ)り」"be, exists.":

Man'yōgana: 可奈之久安里家牟 (Man'yōshū, 4333th)

Modern transliteration:悲(かな)しくありけむ

Since the auxiliary verb of pass tentative mood「けむ」needs to be preceded by infinitive, 「あり」is in infinitive form. And then naturally, the adjective 「悲(かな)し」links to 「あり」 by infinitive (連用形). In Man'yōshū there's also example of 「-かり」.

Man'yōgana: 加奈之可利家理 (Man'yōshū, 793th)

Modern transliteration:悲(かな)しかりけり

Since the auxiliary verb of unwitnessed past「けり」needs to be preceded by infinitive, 「悲(かな)し」is in infinitive form.

So it's reasonable to assume that the infinitive suffix「-かり」is derived from 「-くあり」that had lost its initial u-sound(i.e. sound change of infinitive suffix + 「あり」). There's also similar example about other forms in Man'yōshū.[26]

From above paragraph, we can realize that kari inflection is generally used to link to an auxiliary verbs(so it's also called 「補(ほ)助(じょ)活(かつ)用(よう)」, "complement and auxiliary inflection"), but there's an example to show that the imperative form of kari inflection is an exception of this rule:

はげしかれとは (Senzai Wakashū, 708th)

That is, the imperative form of kari inflection is independently used without linking to any auxiliary verb.(However, it actually expresses a wish but not an order.)

*The Japanese term 悄然 (seuzen, modern shōzen) is a borrowing from Middle Chinese word 悄然 with reconstructed pronunciation /tsʰjɑu nʑǐɛn/,[27] meaning ‘quietly, softly’. Like 悄然 (seuzen), most tari adjectives are derived from Chinese borrowings.

The nari and tari inflections shared a similar etymology. The nari form was a contraction of the adverbial particle「に」and the -r irregular verb「有(あ)り」"be, exist": に + あり → なり, while the tari inflection was a contraction of the adverbial particle と and 有(あ)り: と + あり → たり.

Early Middle Japanese

View on Grokipedia
from Grokipedia
Early Middle Japanese (EMJ) is the stage of the Japanese language used from approximately 800 to 1200 CE, encompassing the Heian period (794–1185) and marking a pivotal transition from Old Japanese through profound phonological, grammatical, and orthographic innovations. This era saw the language become quantity-sensitive, with distinctions between long and short syllables, alongside the loss of earlier morphological pronominal systems and the emergence of lexical terms for speaker and hearer reference. Influenced by intensified contact with Chinese through kanbun-kundoku (reading Chinese texts in Japanese word order) and Sino-Japanese loanwords, EMJ fostered a vibrant vernacular literature that reflected the refined culture of the imperial court.[1] Phonologically, EMJ is defined by extensive simplifications, including the merger of vowel series such as ko-rui and otsu-rui (e.g., /pi1/ and /pi2/ merging to /pi/), and the weakening of consonants like /p/ shifting to /h/ or /w/ in various positions (e.g., Old Japanese apa > EMJ awa). The period's hallmark onbin sound changes reduced syllable complexity, leading to long vowels (CVV), e-moras (CVE), and the loss of glides such as /w/ before /o/, /i/, and /e/ (e.g., Old Japanese yomite > EMJ yoNde). These developments, occurring largely by the 11th century, also introduced bound moras like /Q/ (gemination) and /N/ (nasal coda), while complex onsets such as /kya/ began to emerge, laying groundwork for modern Japanese syllable structure. Additionally, the language shifted to a three-way demonstrative system (proximal–mesial–distal) from Old Japanese's two-way distinction.[1] Grammatically, EMJ featured the retention of verb classes like quadrigrades and bigrades but introduced innovations such as the new shimo ichidan class and the loss of productivity in the nominal verb form, alongside a blurring of conclusive and adnominal distinctions. New auxiliaries proliferated, including causative -sase-, passive -rare-, stative -(i)tar-, and negative -(a)na-, while the copula evolved from ni ar- to nar- and analytic constructions using gerunds with existential verbs like ar- became more common. Particles shifted, with topic marker pa becoming wa, and genitive ga and no gained prominence; honorifics like mi- and o- also developed. The era's kakari-musubi constructions, involving emphatic particles linking to predicate forms for focus, remained prominent, and wordtone emerged as a lexical property governed by principles like Kindaichi’s Law. Syntactically, genitive marking for subjects in subordinate clauses persisted, and differential object marking based on specificity influenced word order, with accusative objects preceding subjects.[1] EMJ texts provide rich attestation of these features, primarily through kana scripts—hiragana (developed from cursive man'yōgana and used extensively by court women) and katakana—alongside kanji-kana majiribun (mixed scripts). Key prose works include Genji Monogatari (c. 1008), Tosa Nikki (935), Makura no Sōshi (c. 1000), and Ise Monogatari (c. 10th century), while poetry anthologies like Kokin Wakashū (905) exemplify the period's aesthetic. Other sources encompass kunten-glossed Chinese texts, early dictionaries such as Ruijū Myōgi Shō (1081), and administrative documents like Tōdaiji Fujūmonko, revealing both vernacular and Sino-influenced registers. These materials highlight EMJ's role in standardizing Japanese as a literary medium, with eastern dialect influences foreshadowing later shifts toward modern forms.

Introduction

Historical Period

Early Middle Japanese (EMJ) encompasses the stage of the Japanese language from approximately 800 to 1200 CE, aligning with the Heian period (794–1185) and the early Kamakura period in Japanese history.[2] This era represents a transitional phase between Old Japanese, associated with the Nara period (710–794 CE), and Late Middle Japanese, which emerged during the Kamakura period (1185–1333 CE). The period is characterized by significant linguistic evolution as Japanese society shifted from the centralized, Buddhist-influenced culture of Nara to a more refined, aristocratic milieu. During EMJ, key linguistic developments included the rise of vernacular literature, which allowed for more natural expression of spoken Japanese beyond classical Chinese models, and the initial integration of Sino-Japanese elements that enriched vocabulary and influenced phonology.[3] These changes reflected broader cultural maturation, with writing practices simplifying to better capture colloquial forms. The sociolinguistic context was dominated by the imperial court in Heian-kyō (modern Kyoto), where elite women and nobles fostered a vibrant literary scene that prioritized aesthetic refinement and emotional nuance in everyday language. Exemplary works like The Tale of Genji (c. 1000–1012 CE), authored by Murasaki Shikibu, exemplify this vernacular shift, depicting courtly life in a style closely mirroring spoken EMJ and moving away from the purer Yamato (native Japanese) forms of the preceding era.[4] This period thus marked the onset of heightened Chinese loanword incorporation, laying the groundwork for the more hybridized lexicon of later stages, while ending the relatively isolated linguistic purity of Old Japanese.[3]

Primary Sources and Influences

The primary sources for Early Middle Japanese (EMJ), spanning roughly 800–1200 CE during the Heian period, consist mainly of literary works in kana and annotated kanbun that capture courtly language and societal norms. The poetry anthology Kokin Wakashū, compiled in 905 CE under imperial order, exemplifies early Heian waka traditions and provides key data on syntax and vocabulary. Prose narratives like Ki no Tsurayuki's Tosa Nikki (935 CE) offer insights into diary-style writing and vernacular expression, while Murasaki Shikibu's Genji Monogatari (ca. 1008 CE) stands as a seminal novel revealing complex narrative structures and dialogue. Earlier compilations such as the Man'yōshū (late 8th century, late Old Japanese) carry over into EMJ analysis through ongoing poetic influence, and commentaries on mythological texts like Kojiki (712 CE) and Nihon Shoki (720 CE) supplement linguistic evidence from administrative and ritual contexts. These sources, often reflecting elite court usage, form the core corpus for studying EMJ morphology and semantics. A dominant external influence on EMJ was Middle Chinese, transmitted via Buddhist scriptures, diplomatic exchanges, and court bureaucracy, which introduced extensive Sino-Japanese lexical borrowings and established on'yomi (Sino-Japanese) pronunciations for kanji. This integration is evident in formal genres like kanbun-kundoku, where Chinese texts were vocalized in Japanese syntax, blending native elements with imported vocabulary and enriching administrative prose. In contrast, influences from Korean or Ainu languages remained negligible during this era, with no significant lexical or structural impacts recorded until later periods.[5] Reconstruction of EMJ phonology and syntax depends primarily on kana-based texts, which emerged prominently in the Heian era and enabled more accurate phonetic notation than prior kanji-only systems. Challenges persist due to the hybrid Sino-Japanese nature of many documents, necessitating methods like phonemic transcription (e.g., the Frellesvig-Whitman system) to isolate native features from borrowings. Coverage is skewed toward the central Yamato dialect of the aristocracy, with scant representation of regional variants.

Writing System

Script Evolution

The script for Early Middle Japanese (EMJ, ca. 800–1200 CE) evolved from the man'yōgana system, which employed Chinese characters (kanji) phonetically to transcribe native Japanese words and grammar, a practice inherited from Old Japanese texts like the Man'yōshū (8th century). During the Heian period, this cumbersome system—requiring hundreds of characters for phonetic values—gave way to simplified syllabaries known as kana, comprising hiragana and katakana, which allowed more efficient representation of vernacular speech.[6] This transition marked a pivotal shift toward phonetic writing, reducing dependence on the logographic and semantically oriented classical Chinese (kanbun).[7] Hiragana emerged around 800 CE as a cursive derivative of man'yōgana, primarily developed by court women for personal and literary expression; for instance, the character い (/i/) originated from the cursive form of the kanji 以 used phonetically in man'yōgana.[6] Katakana, in contrast, developed slightly later in the 9th–10th centuries through angular simplifications of kanji radicals, often for scholarly annotations and Buddhist texts; the character イ (/i/), for example, derives from a portion of the kanji 以.[7] By the 10th century, these scripts coexisted with kanji in mixed orthographies, as seen in Heian documents where hiragana rendered grammatical elements and katakana marked foreign terms or emphasis. A key innovation was the abbreviation of man'yōgana's extensive variants into approximately 46 basic kana symbols per script, reflecting the core syllables of Japanese phonology, though early usage retained hentaigana—diverse variant forms for the same sound, such as multiple cursive styles for /a/—until standardization in the Meiji era (late 19th century).[6] This streamlining facilitated widespread literacy among the aristocracy, particularly women, who favored hiragana (known as onnade no moji, or "women's script") for its fluid aesthetic.[7] Culturally, the kana scripts enabled the phonetic transcription of spoken Japanese, fostering the creation of vernacular literature and diminishing the exclusivity of kanbun to elite male scholars; Heian texts like The Tale of Genji exemplify this through integrated kanji-kana systems that captured native syntax and prosody.[6] Katakana, dubbed otoko no moji ("men's script"), supported technical and diplomatic writing, highlighting gendered divisions in script use that persisted into later periods.

Orthographic Features

Early Middle Japanese orthography relied on kana scripts derived from simplified Chinese characters (man'yōgana), representing moraic units rather than strict phonetic sounds, with hiragana primarily used for native words and grammatical elements, and katakana for annotations or foreign terms.[8] Phonetic-to-orthographic mappings followed historical conventions that preserved Old Japanese distinctions even after phonological mergers, leading to a semi-phonetic system. For instance, the syllable /ma/ was consistently rendered as ま, derived from characters like 麻 or 万. However, inconsistencies arose with sounds undergoing change, such as the representation of post-p-shift /h/, which was typically written as ふ (fu) for hu, retaining the historical spelling.[8] The following table illustrates representative phonetic-to-orthographic mappings for common syllables in Early Middle Japanese kana, highlighting standard forms and noted inconsistencies:
Phonetic SyllableStandard KanaNotes on Inconsistencies
/ma/まConsistent; derived from multiple man'yōgana sources like 麻.
/hu/ふPost-shift /h/; spelling retained as ふ after the sound change from /p/.[8]
/e/えMerged with /ye/ by late Heian; both used え interchangeably.
/i/いStable; no major variants.
/wo/をRepresented rounded /o/; distinct from /o/ as お until later merger.
These mappings reflect the moraic structure, where long vowels or geminates were indicated by repetition or specific diacritics in advanced usage.[9] Spelling variations were common due to ongoing phonological shifts and lack of standardization, particularly in rendering vowel mergers. For example, the sounds /e/ and /ye/ were both spelled as え after their merger around the 10th century, obscuring distinctions present in Old Japanese.[8] Similarly, words like "voice" (koe) were written as こゑ, preserving an archaism unlike modern こえ, and "think" (omou) as おもふ, reflecting historical /f/ for /u/. Okurigana, the kana suffixes attached to kanji for inflectional endings, were widely used to clarify morphology, such as in verbs where the stem remained in kanji and endings in hiragana (e.g., 見る for miru, "to see"). These variations stemmed from the historical kana orthography (rekishi-teki kana-zukai), which prioritized etymological forms over contemporary pronunciation.[9] Special conventions distinguished official and literary writing. The Iroha poem, composed in the 11th century, served as a foundational kana chart, ordering the 47 syllables (excluding /n/) in a non-alphabetical sequence based on a Buddhist verse: いろはにほへとちりぬるを... This pre-gojūon system functioned as an early "alphabet" for memorization and reference, encapsulating the orthographic inventory without repetition. Official documents often employed mixed kanji-kana (majiribun), with kanji for content words and kana for grammar, while women's literature, such as The Tale of Genji, favored pure hiragana for fluid narrative expression, reflecting gender-based script preferences in Heian court culture.[8] Non-standardized hentaigana—variant cursive forms of hiragana, with numerous alternatives for each character by the Heian period—created significant ambiguities, as scribes chose forms based on stylistic or regional preferences, complicating uniform reading. For instance, multiple glyphs like 𛀀 or 𛀁 could represent /a/, drawn from different man'yōgana origins, leading to interpretive challenges in manuscripts. Modern reconstructions address these gaps through comparative analysis of primary texts like kundokugo (vernacular readings of Chinese) and digital corpora, with recent advancements in morphological dictionaries achieving over 97% accuracy in parsing historical spellings.[10][9]

Phonology

Phonological Developments

Early Middle Japanese (EMJ), spanning roughly 800–1200 CE during the Heian period, marked a pivotal transition from Old Japanese (OJ) phonology through several systemic sound changes that simplified the inventory and introduced new structures. These developments, driven by internal evolution and contact with Sino-Japanese vocabulary, reduced distinctions inherited from OJ and established the core phonological framework persisting into later stages of the language. Key shifts included vowel mergers, consonant lenitions, and innovations in syllable structure, all evidenced through comparative analysis of texts like the Genji monogatari and man'yōgana orthography.[1] Vowel mergers were among the most prominent changes, eliminating OJ's eight-vowel system and distinctions between kō-rui (type A) and otsu-rui (type B) syllables, such as /ko1/ versus /ko2/. By the early EMJ (before 950), mergers like /ye/ + /e/ → /e/ occurred, and by ca. 1000, /wo/ + /o/ → /o/, leading to a stable five-vowel system (/a, i, u, e, o/) by late Heian. This simplification is attributed to gradual neutralization, with orthographic evidence in EMJ texts showing inconsistent representation of former distinctions.[11] Consonant shifts further reshaped the system, notably the lenition of initial /p/ to /ɸ/, as in /pito/ → /ɸito/ "person," a change initiating in late OJ but widespread in EMJ. Phonetic palatalization emerged, affecting coronals before /i/ and /j/ (e.g., /ti/ → /tɕi/ "hand"), and velars before /i/, /e/, and /y/ (e.g., /ki/ → [kʲi]), with full affrication of velars developing later. These alterations, reflecting articulatory easing, are documented in EMJ phonetic notations and comparative reconstructions.[11][1] Syllable innovations introduced complexity absent in OJ's predominantly open CV structure. Sino-Japanese loans brought closed syllables (CVC), such as /ten/ "heaven" from Chinese *tʰen/, accommodating nasal codas and expanding prosodic possibilities. Onbin contractions, particularly in auxiliaries and compounds, further reduced forms, though examples like /ɸiru/ retained core shapes amid broader simplifications in verbal endings. These changes enhanced morphological efficiency but varied by register.[1][12] The timeline of these developments is traced via textual evidence, with Genji monogatari (ca. 1008) reflecting mid-Heian mergers and shifts in courtly dialect.[11]

Vowel System

The vowel system of Early Middle Japanese (EMJ), spanning the Heian period (794–1185), consisted of a five-phoneme inventory: /a, i, u, e, o/.[11] This system represented a simplification from the eight-vowel distinctions of Old Japanese, with mergers establishing the core short vowels that persisted into later stages.[11] EMJ developed a phonemic length contrast through onbin sound changes, distinguishing short CV from long CVV/CVE syllables.[11] Phonetically, the mid-Heian realizations of these vowels are reconstructed as [a, i, e̞, o̞, u], with the mid vowels /e/ and /o/ exhibiting centralized and somewhat lax qualities (e̞ and o̞), distinguishing them from the more tense modern counterparts.[11] This laxness in the mid vowels contributed to a more varied acoustic profile compared to the contemporary system, as evidenced by reconstructions drawing on orthographic and poetic data.[11] Diphthongs in EMJ underwent monophthongization, with /ai/ merging into [ɛː] and /au/ into [ɔː], reflecting ongoing vowel coalescence during the period.[11] Following these mergers, sequences like /je/ realized as [je] and /wo/ as [wo] remained distinct before merging into /e/ and /o/ in EMJ.[11] Allophonic variations included vowel raising in specific contexts, such as /i/ shifting to [ɪ] before palatal consonants like /tɕ/ (as in kyō 'today'), influenced by adjacent articulatory features.[11] Evidence for these vowel distinctions and variations comes from rhyme patterns in waka poetry, where conservative usage maintained phonemic separations observable in syllable pairings.[11]

Consonant System

The consonant inventory of Early Middle Japanese (EMJ, ca. 800–1200 CE) was inherited from Old Japanese with notable shifts, particularly the evolution of the bilabial stop /p/ into a fricative series and the emergence of palatal sounds through assimilation processes. The core consonants included voiceless stops /t/ and /k/ (with /p/ transitioning to /h/ in initial position), voiced stops /d/ and /g/ (often prenasalized as [nd, ŋg] in intervocalic contexts, especially in certain dialects), nasals /m/ and /n/, sibilant fricatives /s/ and /z/, and approximants /w/, /j/ (palatal glide), and /r/ (a flap or tap). The velar nasal /ŋ/ did not occur word-initially, surfacing only as an allophone of /n/ before velars, and gemination (/Q/) emerged in native vocabulary through onbin changes during this period.[13][11] A key development was the palatal series, where coronal consonants underwent palatalization before /i/ and /j/: /t/ realized as the affricate /tɕ/ (e.g., *ti > [tɕi] 'hand'), /d/ as /dʑ/ (e.g., *di > [dʑi] 'tongue'), /s/ varying between [s] and the palatal fricative [ɕ] (e.g., *si > [ɕi] 'poem'), and /z/ showing undocumented variations between [z] and [dʑ] in similar environments. Velars showed phonetic palatalization (/k, g/ → [kʲ, gʲ]) before /i, e, y/. The fricative /h/ (from earlier /p/) exhibited allophonic variation, including [h] before /a, o, e/, [ɸ] (bilabial fricative) before /u/, and [ç] (palatal fricative) before /i/, reflecting ongoing lenition from Old Japanese. Prenasalization was prominent for voiced obstruents in non-initial positions, as in sequences like *mVp > [mbV], contributing to their stability in compounds and inflections.[14][15][13][11] Sino-Japanese vocabulary, introduced via Buddhist and administrative texts, expanded the system by incorporating palatal affricates and fricatives not native to EMJ, such as /tɕ/ (e.g., from Middle Chinese *tʰjek > [tɕaku] 'fall') and /ɕ/ (e.g., *ɕiɛt > [ɕi] 'know'). These borrowings often preserved voiceless initials and avoided initial voiced stops, influencing lexical distributions without altering core native phonotactics. Recent analyses, including computational modeling of historical sound changes, have refined understandings of /h/'s allophonic realizations, confirming [ɸ~h] as context-dependent variants across dialects.[16]

Early Middle Japanese (EMJ) syllable structure was predominantly of the consonant-vowel (CV) type, consisting of open syllables such as /ka/ or /ki/, with long syllables appearing as CVV (e.g., tauto- "exalted") or CVE (e.g., punde "brush").[11] This simple CV framework persisted from Old Japanese, but Sino-Japanese loanwords introduced limited codas, including nasal /N/ (e.g., /puNde/ "brush" from onbin changes like OJ /yomite/ > EMJ /yoNde/ "read.GER"), geminate /Q/, and occasional /t/ or /m/ in final position (e.g., in "adne" "rain" or "asa" "morning").[11] Complex onsets were restricted to forms like Cya, Cyo, Cyu, kwa, gwa, kwe, or gwe, maintaining overall simplicity without true clusters.[11] These developments, driven by onbin sound changes in the 8th–10th centuries, added quantity sensitivity to syllables, where short CV counted as one mora and long CVV/CVC as two.[11] EMJ prosody featured a pitch accent system based on binary high-low (H-L) tone patterns at the word level, with four basic melodies in the Kyoto dialect: level high [H], falling [HL], rising [LH], and rising-falling [LHL].[11] Accent was realized as a pitch drop after a high tone, often on the first or subsequent mora (e.g., /'o'oo/ HLL for certain nouns vs. /to'oo/ LHH), and complex words inherited the accent of their initial component.[11] The system was mora-timed, with each mora ideally equal in duration, distinguishing EMJ from stress-timed languages and influencing rhythmic patterns where auxiliaries could form independent prosodic words.[11] Prosodic classes, documented in 11th-century sources like the Ruiju-myōgishō (1081), included patterns such as initial rising (Class 1.3b) or final falling pitch (Classes 2.5, 3.5b, 1.2).[11] Sentence-level intonation in EMJ followed prosodic contours shaped by particles, with questions marked by a rising pitch via the particle ka at the end (e.g., transforming declarative iku "go" to interrogative iku ka "go?").[17] Evidence for these patterns comes from Heian-period poetry scansion, where tanka forms adhered strictly to a 5-7-5-7-7 mora rhythm, as seen in works like the Kokin wakashū (905), emphasizing moraic equality over stress.[18] Recent computational reconstructions, including Bayesian phylogenetic analyses of pitch-accent divergence, place the timing of EMJ accent shifts in the early Heian period (794–900 CE), using dialectal data to model prosodic evolution and address gaps in historical tone documentation.[19]

Grammar

Word Classes

Early Middle Japanese (EMJ), spanning roughly 800–1200 CE, featured a set of word classes that reflected its agglutinative typology, with a basic subject-object-verb (SOV) word order and modifiers typically preceding their heads. The language distinguished major lexical categories through morphological and syntactic behaviors, including inflectional patterns and predicative functions. Nouns formed one of the primary inflectionless classes, lacking markers for gender, number, or case inflection, and often serving as the head of topics in topic-comment structures. They combined with particles to indicate grammatical relations, such as the genitive particle no marking possession or subjects in subordinate clauses, as in hana no saku ("the flower's blooming," where hana "flower" + no functions as subject). Verbs constituted the core inflecting class, obligatorily marking modal and syntactic categories like conclusive (sentence-final) and adnominal (modifier) forms, while tense and aspect were expressed optionally through auxiliaries or context. Adjectives divided into two main subtypes: i-adjectives (also called inflecting or ku-adjectives), which behaved morphologically like verbs by inflecting for tense and polarity with endings such as -shi (conclusive, e.g., takashi "is high") or -ki (adnominal, e.g., takaki yama "high mountain"); and na-adjectives (adjectival nouns), which were non-inflecting and required a copula for predication or modification, functioning more like nouns with nominalizing properties, e.g., samu-ka nari ("is cold," linking to the copula nari). Particles operated as a functional class of uninflecting clitics that attached to hosts like nouns or verbs to specify case, focus, or conjunction, contributing to the language's agglutinative structure without altering the host's form.[20] Minor classes included adverbs, often derived from nominalized verbs, adjectives, or Sino-Japanese loans, serving to modify verbs or other predicates but with relatively limited independent development as a distinct category in EMJ texts. Auxiliaries comprised bound, often defective forms that attached to inflecting words to convey aspect, mood, or evidentiality, integrating into complex predicates; modern analyses emphasize their role in emerging evidential distinctions, particularly through copula-linked forms. Overall, these classes underscored EMJ's head-final syntax, where postpositions like particles followed nouns to build phrases, as seen in case-marking sequences such as noun + accusative wo (though wo began fading in EMJ).

Particles

In Early Middle Japanese (EMJ), particles served as postpositional clitics that attached primarily to nouns or nominalized elements to indicate grammatical relations, marking case, conjunction, or focus within the topic-comment structure of sentences. These particles evolved from Old Japanese (OJ) forms, often derived from copulas or verb endings, and became more prominent as verbal inflections simplified, allowing particles to handle relational marking more explicitly. By the Heian period (794–1185), their use increased, reflecting syntactic shifts influenced by Sino-Japanese literary styles like kanbun kundoku. Case particles in EMJ primarily encoded nominal roles, cliticizing to the end of noun phrases. The particle ga marked subjects, particularly in subordinate clauses, with pronouns, or proper names, evolving from its OJ genitive function to a more specialized nominative role by late EMJ. For example, in Genji monogatari, namida ga indicates the subject "tears" in "tears fall" (namida ga koboreru). The accusative wo (later realized as o due to sound changes) denoted direct objects or paths of motion, as in syuzin-wo ("the wife-[acc.]") from Genji monogatari. Ni functioned datively or locatively, marking indirect objects or destinations, such as ningen-ni ("to people") in existential constructions. The genitive no, derived from the OJ copula, expressed possession or attribution and extended to nominalize clauses, appearing in Genji monogatari as syotyoo no ("of the anthology"). Conjunctive particles linked clauses without full subordination, facilitating sequential or conditional relations. The gerundial te, grammaticalized from OJ verb forms, connected actions in sequence, as in kaite aru ("writing and being") from Genji monogatari. Ba indicated conditionals ("if"), following adnominal verb forms and declining slightly in frequency by late EMJ, exemplified by kakeba ("if [one] writes") in literary texts. The quotative to, originating from the OJ copula infinitive, introduced reported speech or purpose, such as to yuu ("saying that") in Genji monogatari. Binding and focus particles modified scope within the topic-comment framework, often triggering concord phenomena like kakari-musubi that were fading by EMJ's end. Zo provided emphatic or identifying focus, as in ware wo zo ("I [emph.]") from earlier poetry influencing EMJ prose. Ka formed interrogatives or rhetorical questions, altering verb conjugation for doubt, seen in siragiku pa pana ka ("are the unseen flowers not blooms?") from Genji monogatari. Ya conveyed rhetorical emphasis or uncertainty, evolving toward exclamatory uses, as in kimi ya ("you [rhet. q.]") in prose examples. The evolution of particles in EMJ marked a shift from OJ's reliance on verb endings for relations to greater dependence on postpositions, enhancing clause flexibility; for instance, hana ga saku ("flowers-[nom.] bloom") in Genji monogatari illustrates subject marking via ga replacing fused OJ inflections. This trend, driven by prosodic cliticization, integrated particles more tightly with hosts, as noted in EMJ syllable structure.

Verb Morphology

Early Middle Japanese (EMJ) verb morphology retained a complex inflectional system inherited from Old Japanese, characterized by distinct conjugation classes that determined stem alternations across various morphological forms. Verbs inflected obligatorily for syntactic and modal categories, such as conclusive and adnominal forms, while tense, aspect, and voice were primarily expressed through auxiliary attachments. A key innovation in EMJ was the emergence of monograde (ichidan) classes, with upper monograde (e.g., miru "see," stems in i) and lower monograde (e.g., keru "kick," stems in e), arising from mergers of bigrade patterns or new formations. For many verbs, particularly quadrigrades, conclusive and adnominal forms began to blur or coincide. The system featured six primary inflected forms: irrealis (mizenkei, typically ending in -a for quadrigrades), ren'yōkei (conjunctive/infinitive, -i), shūshikei (conclusive, -u), rentaikei (attributive, -u), izenkei (realis, -e), and meireikei (imperative, -e). Verbs were classified into five major regular conjugation classes based on stem structure and vowel alternations, with quadrigrade (yodan) verbs forming the largest group and featuring four distinct stem vowels (a, i, u, e). Bigrade (nidan) verbs, divided into upper (stems in i/u) and lower (stems in e/u) subtypes, exhibited two stem vowels, while monograde classes had a single vowel stem throughout most forms (e.g., lower monograde irrealis/infinitive/conjunctive ke, conclusive keru). Irregular verbs followed idiosyncratic patterns. These classes arose from phonological and morphological regularities, with quadrigrade verbs showing the most extensive alternations, such as kak- "write" yielding kaka (irrealis), kaki (ren'yōkei), kaku (conclusive/attributive), and kake (realis/imperative). For lower bigrade verbs like sin- "die," forms include sine (irrealis/ren'yōkei), sinu (conclusive), sinuru (attributive), and sinare (realis). The following table illustrates the paradigm for the quadrigrade verb kak- "write"*:
FormEndingExampleFunction
Irrealis-akak-aSubordinate clauses, negation
Ren'yōkei (Conjunctive/Infinitive)-ikak-iNominalization, linking to auxiliaries, sequential actions (e.g., kaki-te)
Conclusive-ukak-uSentence-final statements
Attributive-ukak-uModifying nouns
Realis-ekak-eEvidential or conditional contexts
Imperative-ekak-eCommands
For lower bigrade verbs, such as sin- "die"*, the paradigm includes: irrealis/ren'yōkei sine, conclusive sinu, attributive sinuru, realis sinare, imperative sine. Irregular verbs like suru "do" (s-irregular) and kuru "come" (k-irregular) deviated significantly, with suru showing su- (ren'yōkei), su (conclusive), and se-yo (imperative), while kuru had ki- (ren'yōkei), kuru (conclusive), and ko-i (imperative). Stem alternations included the negative form -zu, attached to the irrealis stem (e.g., kaka-zu "not write"), and the passive/causative alternation via auxiliaries like -raru (passive), yielding forms such as kaka-raru "be written". Onbin sound changes further modified stems, introducing nasalization or gemination (e.g., yomi → yoN- in compounds). Tense was not morphologically marked on the main verb but realized through auxiliaries, such as -ki for past (kaki-ki "wrote," later evolving to -(i)ta). Dialectal variations in EMJ conjugations remain underexplored, with most analyses based on central courtly texts like the Genji Monogatari. Recent scholarship has begun to refine understandings of irregular class mergers, noting how forms like the r-irregular ar- integrated into quadrigrade patterns by Late Middle Japanese.

Adjective and Nominal Morphology

In Early Middle Japanese (EMJ), adjectives are classified into two primary categories: inflecting adjectives, known as i-adjectives or keiyōshi (形容詞), and adjectival nouns, known as keiyōdōshi (形容動詞). I-adjectives exhibit verb-like conjugation, featuring a stem followed by inflectional suffixes that produce distinct forms for syntactic functions. The core forms include the shūshikei (conclusive) ending in -shi (e.g., takashi "is high"), rentaikei (attributive) ending in -ki (e.g., takaki yama "high mountain"), and ren'yōkei (adverbial) ending in -ku (e.g., takaku naru "become high"). This pattern parallels verb inflections in structure, though adjectives lack full finiteness distinctions like the imperative seen in verbs. Adjectival nouns, functioning more like nouns, require an adjectival copula for modification and predication, with two subtypes in EMJ: the na-type and the tar-type. The na-type combines the stem with na for attributive modification (e.g., sizu-ka na hito "quiet person"), ni for adverbial use (e.g., sizu-ka ni "quietly"), and nari or da for the conclusive form in predication (e.g., sizu-ka nari "it is quiet"). The tar-type, derived from a fusion of the genitive particle to and the existential verb ari, uses taru attributively (e.g., kirei taru hana "beautiful flower"), tari adverbially (e.g., kirei tari "beautifully"), and tare conclusively (e.g., kirei tare "it is beautiful"). These copulas enable adjectival nouns to nominalize via forms like no or da in certain contexts, such as linking to predicates. Both i-adjectives and adjectival nouns primarily serve prenominal modification, where i-adjectives directly precede nouns (e.g., ōkaki ie "big house") and adjectival nouns insert the copula (e.g., genki na kodomo "healthy child"). In realis contexts, certain inflected forms of i-adjectives convey evidential nuances, implying direct observation or certainty. Unlike modern Japanese, EMJ adjective morphology featured more fused copular elements, such as the productive tar-type, which later declined and survives only in fossilized expressions; additionally, usage was largely gender-neutral, without the stylistic distinctions that emerged in later periods.

Auxiliary Verbs

In Early Middle Japanese (EMJ), auxiliary verbs primarily express aspect, mood, and voice, attaching to non-finite verb forms such as the infinitive to modify the main verb's semantics.[21] These auxiliaries inflect like main verbs but function grammatically, often forming serialized chains where multiple auxiliaries combine to convey layered meanings, such as aspect followed by tense or modality.[21] Unlike core verb inflections, auxiliaries derive from lexical verbs through grammaticalization and attach post-verbally, enabling nuanced expression in prose and poetry.[21] Auxiliaries are roughly classified by function. Aspectual auxiliaries include nu, marking perfective aspect for completed actions (e.g., saki-nu "has bloomed"), and tari, indicating resultative or stative states derived from progressive constructions like -(i)te ari (e.g., sai-tari "is in the state of blooming").[21] The existential ari serves stative functions, often combining with infinitives to denote ongoing or resultant states (e.g., nokori-te ari "remains").[21] Modal auxiliaries encompass mu, expressing negative volitive or conjectural mood (e.g., ke-mu "might be" or "not wish to be"), alongside others like besi for necessity (aru besi "should exist").[21] For voice, raru (or rare) indicates passive constructions (e.g., kakare-ru "is written"), while ari also contributes to stative passives in certain contexts.[21] Recent analyses highlight functional overlaps, where auxiliaries like tari intersect with particles for concessive nuances, though particles handle primary linkage roles.[1] The tense system in EMJ remains non-finite, relying on auxiliary combinations rather than dedicated markers. Past tense emerges through pairings like ki + ari (e.g., kaki-ki ari "has written"), evolving toward simplified forms such as -(i)ta by late EMJ, while future notions arise via irrealis mood with mu or conjecturals like ramu.[21] Serialization allows chains, such as aspectual nu followed by modal mu (e.g., yuk-u nu mu "might have gone"), building complex temporality.[21] In poetry, evidential auxiliaries like miyu (from miye-, "it seems") and meri clarify speaker inference, often attaching to adjectives or verbs for sensory evidentiality (e.g., uruwashi-miyu "seems beautiful").[21] 2024 scholarship refines these as distinct from modals, emphasizing their role in poetic emphasis without direct particle overlap, based on Heian-era texts like the Kokin Wakashū.

Special Inflections

In Early Middle Japanese (EMJ), the mi-inflection represented an archaic pattern derived from Old Japanese (OJ) stative verb morphology, primarily used to express states of existence or predication in subordinate clauses. This inflection, marked by the infinitive-2 form -mi, functioned as a subordinate predicative, conveying "being" or evidentiality, as in yama wo taka-mi ("the mountain being high"), where it nominalizes the adjective for adverbial use. A key example is ari-mi, the mi-inflection of the existential verb ari- ("to exist" or copula), glossed as "is" or "exists," which combined with nouns to form stative predicates like opokimi no kokoro wo yura-mi ("the sovereign's heart being moved") in the Kokin Wakashū (KK 107). This form persisted into early EMJ but became obsolete by the late Heian period (ca. 1000–1185), largely replaced by periphrastic constructions involving auxiliaries like -te ar- for statives. The ku-inflection, another special adjectival pattern, marked the perfective or adverbial form of i-adjectives, often fusing with auxiliaries to indicate a resultant state or completion. In EMJ, it appeared as -ku, as in takaku ("has become high"), where the adjective stem taka- ("high") inflects to adverbialize the perfective sense, sometimes combining with existential ar- to yield takaku ar- ("is high" in a completed sense). This inflection originated in OJ adjectival copula uses, such as samu-ku puku ("blows coldly"), and underwent onbin (sound changes) in EMJ, shifting toward -u (e.g., taka-u), but retained its perfective nuance in literary contexts before declining in Late Middle Japanese. Yōgen, or Sino-Japanese-derived verbs, exhibited unique auxiliary inflections in EMJ, integrating loanwords as verbal nouns predicated by auxiliaries like se- ("to do") or -su for causative functions. For instance, Sino-Japanese roots such as saiizok- ("to dress up," from sauzoku) inflected via -su to form causatives, as in kakas- ("to make write"), attaching to native or borrowed stems to express causation without full independent conjugation. These patterns arose from the influx of Chinese vocabulary during the Heian period, where yōgen verbs adopted defective auxiliary roles, distinct from native quadrigrade or bigrade classes, and were prone to onbin alterations like monophthongization (e.g., kau > koo). These special inflections were retained in early Heian literature, particularly in poetic anthologies like the Kokin Wakashū (compiled ca. 905), where archaic forms enhanced stylistic archaism and evidential tone. Examples include mi-inflected statives in KK 107 for emotional predication and ku-inflected adjectives in seasonal verses to evoke completed states, such as variants of takaku in descriptions of nature. Their gradual obsolescence by late Heian is evident in prose texts, where standard auxiliaries like -(i)tar- supplanted them for statives and perfectives, reflecting broader morphological simplification.
