The Dimasa language is a Tibeto-Burman language spoken by the Dimasa people of the Northeastern Indian states of Assam and Nagaland. The Dimasa language is known to Dimasas as "Grao-Dima" and it is similar to Boro, Kokborok and Garo languages. The Dimasa language is one of the oldest languages spoken in North East India, particularly in Assam, Nagaland.

Etymology

[edit]

The word Dimasa etymologically translates to Children [sa] of the big river [dima]", i.e. the mighty Tsang, which is known as Brahmaputra by the Assamese. The Dimasa word dzi/Dí, meaning water, forms the root of the names of many of the major rivers of Assam and of North East India in general, such as Dibang (plenty of water), Diyung (huge river), Dikrang (green river), Dikhow (fetched water), and many others. The Brahmaputra is known as Tsangi (the purifier) and Lohit is known as Di Lao (long river) among the Dimasas even now.

Many of the important towns and cities in Assam and Nagaland received their names from Dimasa words such as Diphu, Maibang, Dimabang (a capital of the Dimasa Kingdom) etc. In fact, the Dimasa language is one of the last languages of North East India to retain its original vocabulary without being compromised by foreign languages.[2]

Dimasa language

View on Grokipedia
from Grokipedia
Dimasa (autonym: Grao Dima) is a Sino-Tibetan language belonging to the Tibeto-Burman branch, specifically the Bodo–Garo subgroup, spoken primarily by the Dimasa ethnic community in northeastern India. It is mainly used in the Dima Hasao and Cachar districts of Assam state, as well as the Dimapur district of Nagaland, with smaller communities in adjacent areas. According to the 2011 Census of India, Dimasa has approximately 137,184 native speakers, the vast majority (about 131,000) residing in Assam. The language traditionally lacked a standardized but now employs a Latin-based , particularly in primary education and literary works within the . Dimasa speakers are often bilingual or trilingual, incorporating Assamese, Bengali, , or English in daily interactions due to regional linguistic diversity. Linguistically, Dimasa is characterized by its agglutinative structure, with verbs featuring up to 13 suffix slots for , and marking. It has 17 consonants with a voicing contrast, five vowels, and sesquisyllabic words often arising from initial consonant clusters. The variety, which forms the basis of much documentation, lacks lexical tones, distinguishing it from many other . Word formation relies heavily on , alongside prefixation, suffixation, , and . Despite its cultural significance in preserving Dimasa oral traditions, , and identity, the faces challenges from dominant regional tongues, prompting efforts in documentation, digital archiving, and revitalization through and media.

Overview

Classification

Dimasa is classified as a member of the Sino-Tibetan phylum, specifically within the Tibeto-Burman branch. This placement aligns with early linguistic surveys, such as G.A. Grierson's , which situates Dimasa in the Bodo-Naga division of the Assam-Burmese section of Tibeto-Burman. More recent analyses, including Paul Benedict's conspectus, reinforce this affiliation by grouping Dimasa with other northeastern Indian languages exhibiting shared morphological and lexical traits typical of Tibeto-Burman. Within Tibeto-Burman, Dimasa is subclassified under the Bodo-Garo , where it forms part of the Boro-Tiwa-Dimasa- cluster. It maintains close genetic relations with Boro (also known as Bodo), (Tripuri), and Garo, sharing features such as nominal categorial prefixes and noun compounding patterns that distinguish this . These connections are evident in comparative studies of classifiers and lexical items, where Dimasa cognates align closely with its Bodo-Garo relatives, reflecting a common heritage. An alternative classification positions Dimasa within the , sometimes termed Brahmaputran languages due to their concentration around the valley, emphasizing shared innovations like reciprocal verb suffixes and with neighboring Tibeto-Burman varieties. This grouping highlights areal influences and innovations not fully captured in stricter genealogical models. The classification of Dimasa is further shaped by the historical migrations of its speakers, who belong to the ancient Kachari ethnic groups and trace their origins to the of the Brahmaputra and Tsangpo rivers in or around 1000–2500 BCE. These migrations, spanning approximately 500 years and involving routes through the to settlements in , Maibang, and Dima Hasao, contributed to the language's divergence within Bodo-Garo while preserving links to Kachari subgroups like the Bodo and Koch. Such movements, driven by natural calamities and conflicts with groups like the Ahom, underscore the interplay between and linguistic evolution in the region.

Etymology

The name "Dimasa" derives from the components di-ma-sa, where di signifies "water," ma denotes "big" or "great," and sa means "son" or "child," collectively translating to "sons of the big water" or "children of the great river." This etymology refers specifically to the , which holds central significance in Dimasa as a life-sustaining . The term underscores the people's historical ties to riverine environments, where water sources shaped their settlements, livelihoods, and worldview. The autonym for the Dimasa is Grao-Dima, literally " of the big river," with grao indicating "" or "." It is also referred to as Magrau, denoting "mother " and emphasizing its role as the foundational medium of communication and cultural transmission within the . The root di (or variant dzi), meaning "," extends beyond the to influence regional toponymy, reflecting the hydrological landscape of Dimasa-inhabited areas. For instance, derives from di-phu, interpreted as "white " or a place where clear flows through. Similarly, combines di-ma-pur, signifying "city near the great river," highlighting the ancient capital's proximity to the Dhansiri River, a Brahmaputra . These derivations illustrate how the Dimasa encodes their river-dependent heritage in geographic .

Speakers and vitality

The Dimasa language is spoken by approximately 137,184 native speakers in according to the 2011 Census, primarily in the states of and , with recent estimates suggesting a range of 110,000 to 152,000 speakers as of 2025 based on demographic projections and ethnolinguistic surveys. In alone, Dimasa speakers constituted about 35.72% of the population in 2011. Dimasa has gained formal recognition in India's education system, with the Assam government approving it as a medium of instruction in foundational stage schools starting from the 2025-2026 academic year, aligning with the National Education Policy (NEP) 2020's emphasis on . This includes 278 lower primary schools in Dimasa-dominated areas adopting Dimasa as the . In June 2025, it was further approved in principle for inclusion as a (MIL) subject at the degree level under , enabling its integration into higher education curricula. This status supports the development of textbooks and teaching materials in Dimasa. According to UNESCO's assessment framework, Dimasa holds a "vulnerable" vitality status, characterized by intergenerational transmission within families but limited use in public domains and among younger generations. The language faces decline due to the dominance of Assamese as the primary medium in , administration, and media in , leading to reduced proficiency among youth who increasingly adopt Assamese or English for socioeconomic mobility. Despite this, it remains the primary language in home settings for most speakers. Revitalization efforts are led by organizations such as the Dimasa Sahitya Sabha (also known as Dimasa Lairidim Mel or Hosom), a non-profit literary body founded in 1999 that promotes Dimasa through cultural programs, literature publication, and advocacy for script standardization. The group has collaborated on initiatives, including the introduction of Dimasa-medium schooling and workshops to encourage participation. Additionally, digital resources such as online archives of Dimasa , music, and texts are emerging to preserve and disseminate the language, supported by community-driven projects.

Distribution and variation

Geographic distribution

The Dimasa language is primarily spoken in the northeastern Indian states of , , and , with the overwhelming majority of speakers concentrated in Assam's Dima Hasao, Cachar, and Karbi Anglong districts. According to the , Assam accounts for 131,474 Dimasa speakers, representing 95.84% of the national total, with Dima Hasao hosting the largest number at 76,494, followed by Karbi Anglong (21,764) and Cachar (20,579). Smaller populations exist in Nagaland's (4,803 speakers) and negligible numbers in Manipur (36 speakers). The core Dimasa community is centered in Haflong, the administrative headquarters of Dima Hasao district, where they form a significant indigenous presence amid diverse ethnic groups. Diaspora communities have emerged in urban centers like Guwahati, driven by education and employment opportunities, though they remain small and often maintain close-knit social networks. Historically, the Dimasa people originated in the Himalayan foothills near the confluence of the Brahmaputra and Tsangpo rivers in Tibet, migrating southward around 1000–2500 BCE due to environmental pressures like desertification, eventually settling in the Brahmaputra Valley and establishing kingdoms in areas like Dimapur and Maibang. This migration pattern has resulted in scattered pockets across the region's hilly and valley terrains, influenced by conflicts with Ahom rulers and natural calamities. In these locations, Dimasa speakers frequently engage in multilingual practices, coexisting alongside and Bengali in 's and Brahmaputra valleys, and Nagamese in 's , where bilingualism or trilingualism is common for inter-community interaction.

Dialects

The Dimasa language features four major dialects, primarily distinguished by their geographic associations: , spoken in the of and serving as the standard variety; Hawar, found in the Cachar, , and Hailakandi districts of as well as bordering areas of and ; Dembra, prevalent in the and districts of ; and Dijuwa, used in the of and in . These dialects exhibit variations that reflect regional influences, with functioning as the prestige form adopted for literary works and standardized in Roman script. Phonological differences among the dialects include variations in inventories and tonal systems. For instance, the Dijuwa possesses five short s (/i, e, a, o, u/), with /i/ restricted to medial and final positions, alongside five diphthongs and three lexical tones (high, mid, low). In contrast, the Hawar features six short s (/i, e, ə, a, o, u/), including a central schwa (/ə/) that occurs only in medial positions, five diphthongs, and two tones (high and low). Such distinctions contribute to subtle shifts in pronunciation across varieties, though comprehensive comparative studies remain limited. Lexical variations are minor but notable in terms of convergence patterns. The Dijuwa dialect in Dimapur shows closer lexical alignment with Hawar in Cachar, while Hasao in Dima Hasao maintains greater distinctiveness from the others. These differences arise from historical migrations and regional contacts but do not significantly impede communication within the Dimasa speech community.

Phonology

Vowels

The Dimasa language features a vowel inventory consisting of six monophthongal vowels: /i/, /e/, /a/, /ə/, /o/, and /u/, which contrast primarily in height (high for /i/ and /u/, mid for /e/, /ə/, and /o/, low for /a/), backness (front /i/ and /e/, central /ə/ and /a/, back /o/ and /u/), and rounding (unrounded for /i/, /e/, /a/, and /ə/; rounded for /o/ and /u/). These vowels occur in all syllable positions, though /ə/ is restricted to medial positions in some analyses. Allophonic variations include lax realizations of the vowels in certain prosodic contexts, such as [ɪ], [ɛ], [ə], [ɔ], and [ʊ] appearing in the initial syllable of sesquisyllabic words before a tense vowel in the stressed nucleus, as in /brɛ/ realized as [bɛɾe] 'bee'. Additionally, vowel length distinctions emerge in stressed syllables, contributing to durational contrasts that interact with the language's tonal system. In the Latin-based orthography commonly used for Dimasa, these vowels are represented as , , , <ə> (or sometimes <ë>), , and , with <ə> often simplified to in unstressed positions for readability. When written in the Bengali-Assamese (Eastern Nagari) script, vowels are denoted using matras (vowel signs) attached to consonants, such as ি for /i/, এ for /e/, অ for /ə/ or /a/, and ও for /o/, adapting the script's inherent /ɔ/ to approximate Dimasa's central vowels. Dialectal variations in the vowel system are minor; for instance, the Dijuwa exhibits a reduced inventory of five vowels (/i, e, a, o, u/), with /ə/ absent or merged into /a/, and potential fronting of /o/ toward [ø] in some lexical items. These vowels form the nucleus of open syllables in Dimasa's predominantly CV structure.

Consonants

The Dimasa language possesses a inventory consisting of 16 phonemes, categorized into stops, fricatives, nasals, liquids, and glides. The stops feature a phonemic voicing contrast: voiceless /p, t, k/ and voiced /b, d, g/. This is accompanied by the fricatives /ʒ, s, h/, nasals /m, n, ŋ/, liquids /l, r/, and glides /j, w/.

Voicing in the stops serves as a key phonemic distinction, often contrasting meaning in minimal pairs. The fricatives /s/ and /h/ are voiceless, with /ʒ/ as the . Positional allophones occur among certain . For instance, the velar nasal /ŋ/ surfaces as the alveolar in word-initial position, while maintaining [ŋ] elsewhere. Other stops may exhibit allophonic aspiration word-initially. Dialectal variations affect the realization of stops. In some dialects like Hawar, aspirated variants of voiceless stops (e.g., [pʰ, tʰ, kʰ]) may appear, potentially reflecting ongoing sound changes, while the standard variety maintains the voicing contrast without phonemic aspiration.

Suprasegmentals and phonotactics

Dimasa exhibits a syllable structure allowing optional initial consonant clusters, canonically (C)(C)V(N), where the onset may include clusters and the coda is restricted primarily to nasals (/m, n, ŋ/) or glides (/j, w/). This accommodates sesquisyllabic patterns common in the language, with a reduced initial vowel (often /ə/ or lax) in words derived from clusters, such as [məɾam] 'we' from /mɾam/. Closed syllables are less frequent and typically involve these limited coda elements. For instance, words like niŋ (person) illustrate a nasal coda. Dimasa has two primary lexical tones: high and low, with acoustic studies identifying a variable mid tone. Tones are assigned to lexical words regardless of syllable count, distinguishing it within the Bodo–Garo subgroup. Prosodic prominence is also conveyed through stress, which falls predictably on the penultimate of words. In interrogative constructions, a rising pitch accent marks questions, often realized through the sentence-final particle /na/ combined with elevated intonation, as in ziŋ Haflong taŋ-ma na (Are we going to ?). This interacts with the lexical tones. Diphthongs in Dimasa, including /ai/, /au/, /ei/, /ou/, and /eo/, are analyzed as sequences of distinct s rather than unitary phonemes, aligning with the language's of monophthongs /i, e, a, o, u/ and the schwa /ə/. Examples include laj (sky), where /ai/ functions as a vowel cluster within the template. These sequences do not trigger special prosodic rules beyond the general stress and tone assignment. Vowel harmony operates in certain morphological contexts, particularly suffixes, where reduced vowels harmonize with preceding main vowels, enhancing morphological cohesion.

Grammar

Nominal morphology

The Dimasa language lacks grammatical gender and obligatory number marking on nouns, distinguishing it from many but aligning with typical features of Bodo-Garo . Plurality is not morphologically required but can be expressed for human nouns via the additive -raw (e.g., subuŋ-raw '') or associative -tu, while non-human nouns rely on contextual quantification or for distributive or emphatic plurality, such as ma-si ma-si 'one each (of items)'. also serves to intensify nominal concepts, as in bisiŋ bisiŋ 'deep inside'. Dimasa features an agglutinative case system realized through postposed clitics that mark core grammatical functions and spatial relations on s, including pronouns. The nominative is unmarked (∅), serving as the default for subjects (e.g., sisha ' (subject)'). The accusative employs =ke for definite objects (e.g., no=ke 'the house (object)'), while the genitive uses =ni to indicate possession or attribution (e.g., sisha=ni 'of the '). Locative marking appears as =ha, denoting static position (e.g., no=ha 'in/at the house'), and other cases include dative/benefactive =ne for recipients, /comitative =zaŋ for means or , and ablative =nipraŋ (inanimate) or =nisiŋ (animate) for source (e.g., era=nipraŋ 'from here'). These clitics attach to the entire , facilitating flexible . Noun classification in Dimasa is semantic rather than formal, with no inherent classes but reliance on numeral classifiers to categorize referents by animacy, shape, or inherent properties, particularly distinguishing humans from non-humans. Human classifiers include sao- or sa o- (e.g., sao-si 'one person'), while non-human examples encompass ma- for general or flat entities (e.g., ma-si 'one (generic)'), paŋ- for upright plants or trees (e.g., paŋ-si 'one tree'), and taj- for fruit-like or round objects. These bound morphemes prefix numerals and also signal definiteness: the order noun-classifier-numeral denotes definites (e.g., yao gong-gin 'the two hands'), whereas classifier-numeral-noun marks indefinites (e.g., sao-si dang-hoja 'a leader'). Derivational processes enrich the nominal lexicon through and affixation. juxtaposes nouns or noun-verb elements to create compounds, often head-final, such as ha-di 'paddy field' (water-field) or no-bisiŋ 'room' (house-inside), where the semantic whole emerges from the parts. Affixation includes nominalizing suffixes like -ba for actions (e.g., wai-ba 'biting') and diminutives via -sa, especially in kinship terms to convey or generational descent (e.g., reciprocal kin terms with -sa for 'younger' relations). Prefixes like bV- also derive relational nouns, such as body parts or kin (e.g., bupa '').

Verbal morphology

Dimasa verbs exhibit highly agglutinative morphology, with a verb complex featuring up to 13 suffix slots for encoding tense, aspect, mood, and other categories, though typically 0-3 slots are occupied in natural speech. The language distinguishes imperfective and perfective aspects, alongside tense markers that convey non-future, present, and prospective interpretations. Imperfective aspect is realized through suffixes such as -ba for non-future contexts (e.g., aŋ bla gaw-ba 'I shoot an arrow' glossed as 1SG arrow shoot-NF.IPFV) and -du for present ongoing or habitual actions (e.g., Babusri haŋa du-du 'Babusri cooks food' glossed as name food cook-PRES.IPFV). Perfective aspect employs -ka, indicating completion or change of state (e.g., aŋ miziŋ-ka de boŋpaŋ spaj-taɾ-pu-du 'I can go now' glossed as 1SG want-PRF TOP tree break-ENTR-POT-PRES.IPFV). Other aspectual markers include -bi for stative non-future (e.g., haŋa bi 'the house is dirty' glossed as house STAT), -saj for continuative (e.g., ma du-saj 'mother is cooking' glossed as mother cook-CONT), and -ko for durative progressive (e.g., zi-ja-ko 'it is still raining' glossed as rain-NEG-DPROG). Tense is marked separately or in tandem, with -re for split imperfective past habitual or present stative (e.g., 'he used to come here'), a simple past -re, and prospective -ma for future possibility (e.g., 'I will go tomorrow'). Mood is expressed via dedicated suffixes that may co-occur with tense-aspect markers. The uses a zero marker in direct commands or -saŋ for polite forms (e.g., 'come here, please'). employs -tiŋ (e.g., 'let him come'), subjunctive -mu for hypotheticals (e.g., gorai donglaba-mu 'it should have existed' glossed as thing exist-SUBJ), and potential -pu for (e.g., 'I can break the tree'). Deontic obligation is marked by naŋ, commissive commitment by -naŋ, epistemic likelihood by -naj (e.g., glaj-hi-naj-ka 'likely to have fallen' glossed as fall-TRNS.LOC-EPIS-PRF), negative by -ja, and yes/no questions by -na. Multiple mood markers can stack, as in bu dini doŋ-pu-du-mu 'he could have stayed today' (3SG today stay-POT-PRES.IPFV-SUBJ). Voice distinctions include an as the default, with no dedicated affix. reduces valence using the -zaw (e.g., baŋ-zaw 'be much/many' glossed as much-PSV, or 'Raja Gobinda Chandra has been killed'). voice is formed non-productively with prefixes s-, p-, or m- (e.g., pə- + ɾain 'dry.VT' from 'dry.VI'), or productively via the serial verb prefix ɾi- (e.g., ji ri Aju 'feed Grandfather' glossed as eat CAUS grandfather, or tʰu-ɾi 'make sleep' from tʰu 'sleep'). Dimasa lacks dedicated person agreement suffixes on verbs; instead, person and number are indicated by independent pronouns preceding the verb, such as aŋ for first-person singular (e.g., aŋ nu-ba 'I saw' glossed as 1SG see-PAST) and niŋ for second-person singular. Serial verb constructions are productive for expressing complex actions, including adverbial, resultative, applicative, and causative functions. Full serial verbs chain roots to denote sequences like 'reach and come' or 'come and see' (e.g., phai dada hono lungyaba ha basao basao ga phleba nukha 'come and saw trampling'). Causative serials often use ɾi- productively (e.g., 'sweep and cause'), while bound serials occupy postverbal slots for adverbial modification (e.g., -so 'cut in halves'). These constructions allow valence adjustments without dedicated morphology, as in zik pa=ba 'kick and attach' for resultative purposes.

Pronouns and possession

The personal pronouns in Dimasa distinguish three in both singular and plural numbers, without marking. The singular forms are aŋ for the first person (1SG), niŋ for the second person (2SG), and bu for the third person (3SG). The plural forms are ziŋ or jing for the first person (1PL), nisi for the second person (2PL), and busi for the third person (3PL). These pronouns function as subjects, objects, or possessives, integrating with nominal case markers as needed. The first jing (or ziŋ) does not show an inclusive/exclusive distinction. Possession is typically marked by the genitive clitic =ni, which attaches to the possessor noun or . For example, alienable possession is expressed as aŋ=ni libon 'my book', where libon means 'book'. In contrast, inalienable possession, such as terms or body parts, often involves direct juxtaposition without the genitive marker, as in aŋ apa 'my father'. This distinction highlights the language's sensitivity to inherent relational closeness. Emphatic forms of pronouns can be derived by adding clitics or for emphasis, though specifics vary by context. pronouns include /kha/ for 'who', used in questions about referents, such as kha pai-ba? 'Who came?'. These forms are free morphemes that substitute for nouns in constructions.

Syntax

Dimasa exhibits a basic Subject-Object-Verb (SOV) word order in simple declarative sentences, consistent with many , though the order can be flexible due to robust case marking that distinguishes arguments clearly. For instance, the sentence aŋ bɔ́ʃùbúŋ-kʰé mìjà-há nú-bá translates to "I saw this person yesterday," where the subject aŋ ("I"), object bɔ́ʃùbúŋ-kʰé mìjà-há ("this person"), and verb nú-bá ("saw") follow the SOV pattern. In emphatic contexts, Object-Verb-Subject (OV-S) orders may occur, as the postpositional case markers on nouns provide sufficient syntactic clarity without relying strictly on position. Yes/no questions are typically formed by adding the sentence-final particle na or relying on rising intonation, without altering the underlying word order. An example is mkam min-ka na? ("Is the food cooked?"), where na attaches to the declarative mkam min-ka ("The food is cooked"). Wh-questions employ interrogative pronouns such as sɾe ("who"), na-di ("what"), bɾa-ha ("where"), or bede ("how"), which are often fronted for focus, maintaining the SOV order in the remainder of the clause. For example, sɾe = zaŋ uɾa = ha taŋ-pa-ma? means "With whom are you going?" with the wh-word sɾe leading the question. Negation in Dimasa is primarily expressed through verbal suffixes like -ja or -yá, which attach post-verbally, or prefixes such as da- for prohibitive senses, with no major disruption to the SOV structure. A declarative like bu no=ha taŋ ("He goes home") becomes bu no=ha taŋ-ja ("He doesn’t go home") with the suffix -ja. Prohibitives use the prefix, as in da thaŋ ("Don’t go"), derived from the affirmative thaŋ ("go"). For nominal or copular negation, forms like ni-ya or the copula giri apply, such as bo halua ni-ya ("She/he is not a cultivator"). Complex clauses in Dimasa include , which are prenominal and formed using the relativizer jaba (or variants like jaɾaw), nominalizing the preceding to modify a head . An example is aŋ soŋ= jaba samlaj=ke (" I cooked"), where soŋ= jaba relativizes of cooking to describe samlaj ("dish"). The specifier gin may optionally precede jaba for emphasis within the relative clause, as in constructions indicating agency or . Coordination links clauses or phrases with conjunctions like ode or odehe ("and"), preserving SOV in each ; for instance, niŋ no=ha taŋ odehe aŋ=ke phone klaj ("You go home and call me"). Complement clauses use nominalizers like ba or multi-suffix verbs, as in aŋ bu ɾep= ba =ke nu-du ("I can see that he is writing").

Lexicon and writing

Core vocabulary and loanwords

The core vocabulary of Dimasa, a Tibeto-Burman of the Bodo-Garo , consists primarily of monosyllabic roots that reflect retained Proto-Tibeto-Burman elements, particularly in s related to basic human experience and the natural environment. For body parts, common terms include bokhro 'head', mu-taj 'eye', b-jaw 'hand', yathep 'leg', and sao 'body', many of which derive from Tibeto-Burman roots such as mik for 'eye'. Numbers feature classifiers in counting, with basic cardinals like ma-si 'one', magin 'two', saintham 'three', and bonwa 'five', often compounded for specificity. terms emphasize familial roles, such as baba '', amaj '', n-pa 'your father', b-da 'his brother', and nobra '', showing patterns of possession through prefixes. In the of nature, Dimasa preserves Tibeto-Burman roots like dzi or di 'water' (seen in compounds such as di-koŋ 'river' from klyoŋ), hadi 'rain', sajn 'sun', hagra 'jungle', and hading 'hill', contrasting with innovations in agricultural terms like hadzi ''. Loanwords in Dimasa predominantly enter from neighboring , reflecting historical contact in , as well as from English due to colonial and modern influences. From Assamese and Bengali, borrowings include bisa 'twenty', somoj 'time', rajniti '', kopal 'luck', and bosta 'sack', often adapted phonologically to fit Dimasa patterns; these are common in administrative and everyday domains. English loans cover modern concepts, such as school '', doctor 'doctor', train '', station 'station', pass 'pass', and minister 'minister', integrated without significant alteration. Indo-Aryan influences also appear in terms like mouzari 'area officer', highlighting borrowings for governance. Word formation in Dimasa lexicon employs to convey plurality or distributive meanings, a process typical of . Full marks nouns, as in lamá lamá 'roads' or ma-si ma-si 'one each' for equal distribution. Partial or iterative creates adverbs or intensified actions, such as kase-kase 'small ones' (), su su 'go around without intent', min min 'on and on', or skang skang 'before before'. Dialectal variants occasionally affect lexical choices, such as regional preferences for certain or nature terms.

Writing systems and orthography

The Dimasa language utilizes two main writing systems, reflecting regional variations in its usage. In the , the Latin alphabet is predominant, incorporating diacritics such as ə for the schwa (/ə/) and ŋ for the velar nasal (/ŋ/) to accommodate specific phonological features. In the , the Bengali-Assamese script (Eastern Nagari) is more commonly employed, aligning with the linguistic environment shared with Bengali and Assamese speakers. Historically, Dimasa maintained a strong with no indigenous script until the , when written forms began to develop; the was among the earliest adopted, likely influenced by Christian missionary activities in that promoted for related . initiatives gained momentum in the through organizations like the Dimasa Lairidim Hosom, a key literary group, and the Dimasa Sahitya Sabha, which in 2004 officially endorsed a unified orthography based on the Hasao dialect to foster consistency in writing. This effort supports encoding, leveraging the existing block and the Bengali block (U+0980–U+09FF) for digital representation in both systems.
