A lexical set is a group of words that share a particular vowel or consonant sound.

A phoneme is a basic unit of sound in a language that can distinguish one word from another. Most commonly, following the work of phonetician John C. Wells, a lexical set is a class of words in a language that share a certain vowel phoneme. As Wells himself says, lexical sets "enable one to refer concisely to large groups of words which tend to share the same vowel, and to the vowel which they share".[1] For instance, the pronunciation of the vowel in cup, luck, sun, blood, glove, and tough may vary in different English dialects but is usually consistent within each dialect and so the category of words forms a lexical set,[2] which Wells, for ease, calls the STRUT set. Meanwhile, words like bid, cliff, limb, miss, etc. form a separate lexical set: Wells's KIT set. Originally, Wells developed 24 such labels—keywords—for the vowel lexical sets of English, which have been sometimes modified and expanded by himself or other scholars for various reasons. Lexical sets have also been used to describe the vowels of other languages, such as French,[3] Irish[4] and Scots.[5]

There are several reasons why lexical sets are useful. Scholars of phonetics often use abstract symbols (most universally today, those of the International Phonetic Alphabet) to transcribe phonemes, but they may follow different transcribing conventions or rely on implicit assumptions in their exact choice of symbols. One convenience of lexical sets is their tendency to avoid these conventions or assumptions. Instead, Wells explains, they "make use of keywords intended to be unmistakable no matter what accent one says them in".[1] That makes them useful for examining phonemes within an accent, comparing and contrasting different accents, and capturing how phonemes may be differently distributed based on accent. A further benefit is that people with no background in phonetics can identify a phoneme not by learned symbols or technical jargon but by its simple keyword (like STRUT or KIT in the above examples).[2]

Standard lexical sets for English

[edit]

The standard lexical sets for English introduced by John C. Wells in his 1982 Accents of English are in wide usage. Wells defined each lexical set on the basis of the pronunciation of words in two reference accents, which he calls RP and GenAm.[6]

Wells classifies English words into 24 lexical sets on the basis of the pronunciation of the vowel of their stressed syllable in the two reference accents. Typed in small caps, each lexical set is named after a representative keyword.[9] Wells also describes three sets of words based on word-final unstressed vowels, which, though not included in the standard 24 lexical sets (the final three sets listed in the chart below) "have indexical and diagnostic value in distinguishing accents".[10]

For example, the word rod is pronounced /ˈrɒd/ in RP and /ˈrɑd/ in GenAm. It therefore belongs in the LOT lexical set. Weary is pronounced /ˈwɪərɪ/ in RP and /ˈwɪrɪ/ in GenAm and thus belongs in the NEAR lexical set.

Some English words do not belong to any lexical set. For example, the a in the stressed syllable of tomato is pronounced /ɑː/ in RP, and /eɪ/ in GenAm, a combination that is very unusual and is not covered by any of the 27 lexical sets above.[11] Some words pronounced with /ɒ/ before a velar consonant in RP, such as mock and fog, belong to no particular lexical set because the GenAm pronunciation varies between /ɔ/ and /ɑ/.[12]

The GenAm FLEECE, FACE, GOOSE, and GOAT range between monophthongal [i, e, u, o] and diphthongal [ɪi, eɪ, ʊu, oʊ], and Wells chose to phonemicize three of them as monophthongs for the sake of simplicity and FACE as /eɪ/ to avoid confusion with RP DRESS, /e/.[13]

The happY set was identified phonemically as the same as KIT for both RP and GenAm, reflecting the then-traditional analysis, although realizations similar to FLEECE (happy tensing) were already taking hold in both varieties.[14] The notation ⟨i⟩ for happY has since emerged and been taken up by major pronouncing dictionaries, including Wells's, to take note of this shift.[15] Wells's model of General American is also conservative in that it lacks the cot–caught (LOT–THOUGHT) and horse–hoarse (NORTH–FORCE) mergers.[8]

Choice of the keywords

[edit]

Wells explains his choice of keywords ("kit", "fleece", etc.) as follows:

The keywords have been chosen in such a way that clarity is maximized: whatever accent of English they are spoken in, they can hardly be mistaken for other words. Although fleece is not the commonest of words, it cannot be mistaken for a word with some other vowel; whereas beat, say, if we had chosen it instead, would have been subject to the drawback that one man's pronunciation of beat may sound like another's pronunciation of bait or bit.[9]

Wherever possible, the keywords end in a voiceless alveolar or dental consonant.[9]

Usage

[edit]

The standard lexical sets of Wells are widely used to discuss the phonological and phonetic systems of different accents of English in a clear and concise manner. Although based solely on RP and GenAm, the standard lexical sets have proven useful in describing many other accents of English. This is true because, in many dialects, the words in all or most of the sets are pronounced with similar or identical stressed vowels. Wells himself uses the Lexical Sets most prominently to give "tables of lexical incidence" for all the various accents he discusses in his work. For example, here is the table of lexical incidence he gives for Newfoundland English:[16]

  • KIT: ɪ
  • DRESS: ɛ
  • TRAP: æ
  • LOT: ɑ
  • STRUT: ɔ̈
  • FOOT: ʊ
  • BATH: æː
  • CLOTH: ɑː
  • NURSE: ɜr [ɝ:]
  • FLEECE: iː
  • FACE: ɛː, ɛɪ
  • PALM: æ, ɑː
  • THOUGHT: ɑː
  • GOAT: ʌʊ
  • GOOSE: uː
  • PRICE: əi
  • CHOICE: əi
  • MOUTH: əu
  • NEAR: ɛr
  • SQUARE: ɛr
  • START: ær
  • NORTH: ɔ̈r
  • FORCE: ɔ̈r
  • CURE: ɔ̈r
  • happY: [i]
  • lettER: ər [ɚ]
  • commA: ə

The table indicates that, for example, Newfoundland English uses the /ɪ/ phoneme for words in the KIT lexical set, and that the NORTH, FORCE and CURE sets are all pronounced with the same vowel /ɔ̈r/. Note that some lexical sets, such as FACE, are given with more than one pronunciation, which indicates that not all words in the FACE lexical set are pronounced similarly (in this case, Newfoundland English has not fully undergone the pane–pain merger). /ɔ̈/ is a back vowel [ɔ]; Wells uses the symbol ⟨ɔ̈⟩ so that the reader does not confuse it with the THOUGHT vowel (which, in the case of many other accents, he writes with ⟨ɔ⟩ or ⟨ɔː⟩).[17]

Wells also uses the standard lexical sets to refer to "the vowel sound used for the standard lexical set in question in the accent under discussion":[18] Thus, for example, in describing the Newfoundland accent, Wells writes that "KIT and DRESS are reportedly often merged as [ɪ]",[19] meaning that the stressed syllables of words in the KIT lexical set and words in the DRESS lexical set are reportedly often pronounced identically with the vowel [ɪ].

Lexical sets may also be used to describe splits and mergers. For example, RP, along with most other non-rhotic accents, pronounces words such as "father" and "farther" identically. This can be described more economically as the merger of the PALM and START lexical sets. Most North American accents make "father" rhyme with "bother". This can be described as the merger of the PALM and LOT lexical sets.

Origin

[edit]

In a 2010 blog post, Wells wrote:

I sometimes think that a century from now my lexical sets will be the one thing I shall be remembered for. Yet I dreamt them up over a weekend, frustrated with the incoherent mess of symbols used in such contemporary publications as Weinreich's "Is a structural dialectology possible?".[20]

He also wrote that he claimed no copyright in the standard lexical sets, and that everyone was "free to make whatever use of them they wish".[20]

Extensions

[edit]

Some varieties of English make distinctions in stressed vowels that are not captured by the 24 lexical sets. For example, some Irish and Scottish accents that have not undergone the fern–fir–fur merger split the NURSE lexical set into multiple subsets. For such accents, the 24 Wells lexical sets may be inadequate. Because of this, a work devoted to Irish English may split the Wells NURSE set into two subsets, a new, smaller NURSE set and a TERM set.[21]

Some writers on English accents have introduced a GOAL set to refer to a set of words that have the GOAT vowel in standard accents but may have a different vowel in Sheffield[22] or in south-east London.[23] Wells has stated that he didn't include a GOAL set because this should be interpreted as an allophone of GOAT that is sensitive to the morpheme boundary, which he illustrates by comparing the London pronunciations of goalie and slowly.[24]

Schneider et al. (2004), which documents the phonologies of varieties of English around the world like Wells (1982), employs Wells's standard lexical sets as well as the following supplementary lexical sets, as needed to illustrate finer details of the variety under discussion:[25]

  • GOAL, discussed above
  • horsES, officEs, paintEd and villAge, all referring to the unstressed allophone of KIT that is subject to the weak vowel merger
  • MARY, MARRY and MERRY, for the allophones of FACE (SQUARE in non-rhotic dialects), TRAP and DRESS before intervocalic /r/, commonly subject to Mary–marry–merry merger in North American English
  • MIRROR and NEARER, for the allophones of KIT and FLEECE before intervocalic /r/, commonly subject to mirror–nearer merger in North American English
  • treacLE and uncLE, both referring to the vocalized /əl/

Other supplementary lexical sets include:

  • PASTA, pronounced the same as TRAP in the UK and as PALM in the US (the opposite of the BATH vowel)
  • OFF, which is the same as Wells's CLOTH.
  • HEAD, BIRTH, BERTH, PRIZE, AFTER, NEVER, STAY, STONE, STAND, DO, ONE, SNOW, BOAR, POWER, FIRE, EARS, TUESDAY, NEW, ORANGE, KITTEN, DANCE, TOMORROW, LOUD, HAND, PIN, PEN, THINK, LENGTH, GOING, POOL, PULL, FEEL, FILL, FAIL, FELL, COW, STAR, FIT, CUP, PIECE, BROAD, LOOSE, EIGHT, metER, BEER, BARE, BACK, BED, TERM, SPHERE, ZERO, carrIER, cordIAL, cUrious, TRUER, TRUANT, About, IT, SIT, LAYER, BITE, BIDE, BYRE, BILE, BOUT, BOWED, BOWER, BOWEL, DOOR, POOR

Lexical set

View on Grokipedia
from Grokipedia
In , a lexical set is a group of words in English that share the same or in their citation forms within reference accents such as (RP) and General American (GenAm), serving as a standardized framework for analyzing phonological variations across dialects. This approach groups words based on their typical in these reference varieties, allowing linguists to track how sounds evolve, merge, or split in different regional or social accents of English. The concept was introduced by phonetician in his three-volume work Accents of English (, 1982), where he proposed 24 "standard" lexical sets to simplify the description of English vowel systems. Wells defined each set using a keyword that exemplifies the group, such as KIT for words like ship, bit, and myth (typically /ɪ/ in RP and GenAm); for step, bet, and threat (/e/ or /ɛ/); and TRAP for tap, cat, and plaid (/æ/). These keywords were chosen for their clarity and frequency, often ending in voiceless consonants to highlight the vowel sound without interference from following phonemes. Lexical sets have become a cornerstone in phonetic and sociolinguistic research, enabling precise comparisons of accents—for instance, the merger of LOT and THOUGHT sets (e.g., stop and taught) in many North American varieties, or the distinction between BATH and TRAP in RP but not in General American. Extensions to the original sets, such as happY, lettER, and commA, account for unstressed vowels and have been adopted in studies of World Englishes and language teaching. By focusing on equivalence classes rather than abstract phonemes, lexical sets provide a practical tool for transcription, dialectology, and pronunciation pedagogy, emphasizing real-word behavior over isolated sounds.

Definition and Purpose

Core Concept

A lexical set is a group of words in a that share the same , typically a vowel sound, enabling systematic comparison of pronunciation across dialects without dependence on . This approach groups words based on their consistent behavior in reference accents, such as and General American, where the phoneme remains the same despite variations in realization. The concept was introduced by phonetician to standardize discussions of accent differences. Lexical sets represent phonemic categories that can exhibit variability in phonetic quality between accents; for instance, the vowel quality in a given set might differ in height or frontness while preserving phonemic identity. To illustrate, the KIT lexical set includes words like "kit," "bit," and "sit," all sharing the phoneme /ɪ/ in reference accents, allowing researchers to track how this sound shifts across varieties without listing every word. This grouping principle highlights the abstract phonemic unity underlying surface-level phonetic diversity. Originally formalized for English vowels, the framework of lexical sets has been extended to words from other languages, such as Irish and Scots, and applied to in limited cases by subsequent researchers.

Advantages and Usage Principles

Lexical sets provide a concise method for describing phonetic variations in English accents, allowing linguists to refer to groups of words sharing the same without detailing each instance individually. For example, stating that "the TRAP is raised in this " efficiently captures the pronunciation shift for all words like trap, , and man in that variety. This approach, as articulated by Wells, enables reference to "large groups of words which tend to share the same , and to the which they share," streamlining discussions of accent differences. A key advantage is their accessibility to non-specialists, as they bypass the need for familiarity with International Phonetic Alphabet (IPA) symbols, making phonetic analysis approachable for educators, actors, and language learners. Additionally, lexical sets maintain neutrality across transcription traditions, such as the Cardinal Vowel system or other phonetic notations, by relying on unambiguous keywords rather than accent-specific symbols. In usage, lexical sets are referenced by a representative keyword that evokes the shared vowel sound, such as KIT for the high front lax vowel /ɪ/ in words like bit and ship. They effectively capture phonological phenomena like mergers and splits; for instance, the father-bother merger in many North American accents equates the vowels in the LOT and PALM sets. Principles emphasize alignment with reference accents, particularly (RP) for and General American (GenAm) for North American varieties, to ensure consistent comparison across dialects. While versatile for vowel analysis, lexical sets are primarily designed for stressed vowels and have limited scope for unstressed ones or consonants, where applications remain rare and non-standard.

Historical Development

Introduction by John Wells

John Christopher Wells (born 11 March 1939) is a British phonetician and Emeritus Professor of at , where he held positions from 1961 until his retirement in 2006. As a , Wells has contributed extensively to the fields of , , and . His most influential work in English accentology is the three-volume Accents of English, published in 1982 by . In Accents of English, Wells first systematically presented lexical sets as a tool for describing and comparing pronunciations across English varieties, addressing the challenges posed by inconsistent phonetic notations in prior dialectological studies. This framework groups words by their shared behavior in reference accents, enabling precise analysis without ambiguity in symbol usage. The concept emerged rapidly during a weekend in early 1982, driven by Wells' frustration with the ad hoc and varying symbols in works like Uriel Weinreich's 1954 article "Is a Structural Possible?". In a entry on his , Wells shared this personal , describing how he devised the sets in a burst of inspiration without preliminary testing and later hoped they would endure as his primary legacy in . Wells' initial formulation included 24 lexical sets for stressed vowels and diphthongs, supplemented by three sets for unstressed vowels, centered on the reference accents of (RP) and General American (GenAm). Drawing from earlier phonological approaches, this innovation prioritized dialectological clarity by defining sets through intersecting vowel incidences in the reference varieties. The choice of representative keywords followed principles aimed at minimizing cross-accent confusion, such as favoring monosyllabic forms ending in voiceless consonants.

Selection of Keywords

The selection of keywords for lexical sets follows specific criteria to ensure they reliably represent the prototype sounds across major English accents, particularly (RP) and General American (GenAm). Keywords are chosen to be monomorphemic and, where possible, monosyllabic, facilitating clear phonological analysis without morphological complications. They must also be high-frequency words in everyday use, unrestricted to specific dialects or registers, to promote broad applicability and familiarity. Additionally, spellings are selected for unambiguous , avoiding irregular or dialect-specific orthographic irregularities that could confound identification. John Wells devised the keywords to evoke the core of each set while minimizing influence on quality; as far as possible, they end in a voiceless alveolar or , such as /t/ or /s/, to reduce potential coarticulatory effects. For instance, KIT represents the short front high /ɪ/, and LOT denotes the /ɒ/ in RP or /ɑ/ in GenAm, selected for their prototypical realization in both reference accents. This process involved identifying the of incidences between RP and GenAm, ensuring the 24 stressed sets plus 3 unstressed sets comprehensively cover major English distinctions without overlap. Challenges in selection included avoiding homophones or words that could merge with other sets upon vowel substitution, prioritizing unambiguous representatives like FLEECE over BEAT to prevent confusion. Dialect-specific irregularities were sidestepped to maintain neutrality, though some sets, such as PALM, proved inherently variable due to historical mergers. Wells developed these over a single weekend, drawing on phonetic intuition to balance precision and practicality. Post-1982 publication in Accents of English, the core keywords have remained unchanged, with only minor adjustments based on user feedback and proposals for subsets in non-standard accents like Scottish or Irish English, preserving the system's foundational integrity.

Standard Lexical Sets

Monophthong and Diphthong Sets

The standard lexical sets for stressed monophthongs and in English, as defined by phonetician J.C. Wells, comprise 24 categories that group words sharing the same across accents, facilitating comparisons between varieties like (RP) and General American (GenAm). These sets focus on prototypical keywords, each representing a phonemic class, with realizations varying by accent; for instance, monophthongs like KIT denote short high front s, while like FACE represent rising front glides. The following table summarizes the sets, including keywords, example words, and typical phonetic realizations in RP and GenAm, drawn from Wells' framework.

FORCEore, roar, floor/ɔː//ɔr/
CUREpoor, pure, tourist/ʊə//ʊr/
Each set plays a distinct phonemic role in the English vowel system; for example, TRAP serves as the short front low vowel, contrasting with BATH, which is its long counterpart in RP but often merges with TRAP in GenAm. Common variations include the BATH-TRAP split, where RP lengthens the vowel before certain consonants, while many American accents do not. Mergers are also prevalent, such as the LOT-THOUGHT merger in GenAm, where both are realized as /ɑ/ or /ɔ/, and the NORTH-FORCE merger, which holds in non-rhotic accents like RP (/ɔː/ for both) but is maintained in rhotic accents like GenAm through the r-colored /ɔr/. These sets provide a neutral framework for describing stressed vowels, highlighting how accents differ in quality, length, and diphthongization without altering lexical distribution.

Unstressed Vowel Sets

In addition to the lexical sets for stressed vowels, John Wells introduced three sets specifically for unstressed vowels to provide a comprehensive framework for describing English variations, particularly in reduced or weak syllables that often undergo not captured by stressed sets. These sets—happY, lettER, and —focus on common patterns in non-stressed positions, such as word-final or medial syllables, and highlight phonemic distinctions in accents like (RP) and General American (GenAm). They are essential for analyzing reductions, mergers, and tensing trends in unstressed contexts, enabling precise comparisons across dialects. The happY set encompasses the in unstressed final syllables of words like "happy," typically a high that exhibits variation between lax and tense realizations. In traditional descriptions, it was lax /ɪ/, but a process known as happy tensing has led to a tense /i/ in many modern accents, reflecting a shift toward smoothing the distinction from the FLEECE in stressed positions. Examples include "," "," and "." In RP, it is now commonly /i/, while in GenAm, it is also /i/ across most regions, though some Southern varieties retain /ɪ/. This set captures the trend of tensing in word-final unstressed positions, affecting about 4% of English . The lettER set refers to the vowel in unstressed syllables spelled with "er" or similar, often in non-final positions, and is realized as a mid-central vowel, merging with schwa in non-rhotic accents but distinct in rhotic ones. It highlights reductions in syllables like those in "letter" or "better," where the vowel is weakened but influenced by following "r." In RP (non-rhotic), it is /ə/, aligning with commA, whereas in GenAm (rhotic), it is /ɚ/, an r-colored schwa. Examples include "after," "water," and "butter." This set is crucial for distinguishing rhoticity's impact on unstressed vowels. The commA set covers the ultimate schwa or weak vowel in unstressed syllables, particularly in word-final positions without "r," representing the most frequent reduced vowel in English due to its prevalence in function words and suffixes. It is prototypically /ə/ across accents, embodying full vowel reduction in casual speech. Examples include "comma," "sofa," "idea," "about," and "original." In both RP and GenAm, it is /ə/, though GenAm may show /ɚ/ in some r-colored contexts or mergers with /ɪ/ in certain dialects; it remains the core neutral vowel for weak forms. This set completes the unstressed framework by addressing pervasive schwa usage.

Applications

In Phonetic Description of Accents

Lexical sets serve as a standardized framework for analyzing and comparing realizations across English accents, enabling phoneticians to describe systematic variations without relying solely on International Phonetic Alphabet (IPA) transcriptions. By grouping words that share the same in reference accents like (RP) or General American (GenAm), these sets facilitate the identification of mergers, shifts, and distinctions in diverse dialects. For instance, they highlight how accents diverge in the pronunciation of specific sets, such as the monophthongal realization of the GOAT set in as /oː/ rather than the /əʊ/ found in RP. This approach allows researchers to map phonetic correspondences efficiently, emphasizing phonological patterns over isolated word pronunciations. In accent analysis, lexical sets are particularly useful for documenting mergers, where historically distinct vowels converge. The LOT/THOUGHT merger, also known as the cot-caught merger, exemplifies this: in many North American accents, words like cot and caught share a low back vowel /ɑ/, whereas RP maintains a distinction with /ɒ/ for LOT and /ɔː/ for THOUGHT. Similarly, the NURSE set often merges with SQUARE in rhotic accents like GenAm (/ɜːr/), but remains distinct in non-rhotic varieties such as Scottish English. These mergers reveal historical sound changes and regional influences, aiding in the classification of accents as rhotic or non-rhotic. For example, the START and PALM sets merge in non-rhotic RP (/ɑː/), but in rhotic accents, START includes a post-vocalic /r/ (/ɑr/), preserving a perceptual difference from the monophthongal PALM /ɑ/. Dialect comparisons leverage lexical sets to trace sound correspondences and shifts. In , the TRAP set shows an allophonic split where the before nasal is nasalized and raised in height (e.g., to [ɛə] or higher in some speakers), as part of ongoing sound changes. This contrasts with the more open /æ/ in GenAm, illustrating how sets capture evolutionary divergences. Likewise, , a southeastern British variety, features a diphthongal shift in the FACE set, pronounced as /æɪ/ or /aɪ/ (e.g., face as [fæɪs]), blending elements of and RP. In (AAVE), the set undergoes monophthongization, reducing /aɪ/ to [aː] in words like time, except before voiceless consonants, which differentiates it from mainstream diphthongs. Methodologically, lexical sets enhance phonetic surveys and recordings by providing keyword proxies that represent broader phonological categories, reducing the need for full IPA notation in initial data collection. Phonologists recommend eliciting words from key sets during fieldwork to systematically probe variations, as this method ensures comparability across speakers and accents without overwhelming participants with technical symbols. For , this facilitates quantitative analysis of formant values and qualitative descriptions of mergers, supporting cross-regional studies.

In Language Teaching and Learning

Lexical sets play a significant role in English as a (ESL) and English as a (EFL) by simplifying the of through targeted drills. By grouping words that share the same across accents, such as the KIT set (e.g., bit, ship, sick) and set (e.g., bet, step, neck), instructors can focus on minimal pairs to highlight contrasts, helping learners distinguish subtle differences without overwhelming them with isolated . This approach, introduced by John Wells, facilitates systematic practice of articulation, including and positioning, and is integrated into dictionaries and materials for practical application. In ESL contexts, lexical sets aid learners in navigating accent variations, such as the set pronounced as /ʌ/ in both British and but with differing realizations in other varieties (e.g., more open in some Australian accents), or the BATH set with /ɑː/ in Southern versus /æ/ in General American. This enables targeted exercises to build awareness of regional differences, improving intelligibility in communicative settings. Resources like apps (e.g., those incorporating Wells' sets for audio drills) and textbooks often employ these groupings for self-study and classroom activities, allowing learners to practice sets in context through dialogues or recordings. Studies on instruction post-2000 demonstrate that such structured methods contribute to improved learner outcomes, with meta-analyses showing moderate effect sizes (d = 0.46) for targeted training on overall proficiency and comprehensibility. In actor training and dialect coaching, lexical sets provide a framework for grouping words to master specific accent features, making accessible for performance preparation. For instance, coaches use the set (e.g., , , move) to teach the monophthongal /uː/ in a Southern accent, contrasting it with the diphthongal glide in other , through repetition and contextual phrases to ensure consistent vocal delivery. Theater resources, including open-access guides, recommend simplified lists of these sets for beginners, drawing on Wells' original framework to streamline acquisition without requiring full knowledge. This method enhances actors' ability to switch accents fluidly, with from training programs highlighting faster proficiency gains in rehearsal settings. The benefits of lexical sets in both ESL/EFL and actor training lie in their approachable structure, which demystifies complex and promotes retention through thematic grouping rather than rote . By prioritizing conceptual understanding over exhaustive lists, these sets foster confidence in , supported by indicating that systematic, accent-focused instruction leads to measurable improvements in learner accuracy and self-perception post-intervention.

In adaptations for Anglo-Welsh English, David Parry extended Wells's lexical sets to better capture the phonological influence of Welsh on rural dialects. These modifications, detailed in Parry's analysis of data from the Survey of Anglo-Welsh Dialects (1968–1990), also address mergers like SQUARE and NEAR in border regions, where words such as "square" and "near" may converge on a like /ɛə/ or /ɛː/ due to substrate effects from Welsh. Parry (1999) emphasizes how these extensions facilitate mapping vowel variation across southeast, northeast, and localities. For Irish English, revisions to the lexical sets account for distinctions not present in RP or General American, notably splitting the NURSE set into NURSE and TERM to reflect a back rounded [ʊə] or [ɜː] in "nurse," "work," and "" versus a front unrounded [ɛː] in "term," "learn," and "." The lettER set, representing unstressed syllables like "letter" and "better," is often realized as a reduced /ə/ or centralized vowel, sometimes merging with commA but distinct from stressed NURSE/TERM in local varieties. Raymond Hickey (2005) outlines these augmented sets for Dublin English, noting their utility in describing urban innovations like the SQUARE/NURSE merger in some speakers, where both sets shift to /ɛː/. Wells (1982) similarly observes the NURSE/lettER revision in broader Irish contexts, attributing it to historical /r/ effects. In Scots varieties of English, the GOAT set exhibits unique monophthongal realizations, typically or [oː] in words like "goat," "home," and "boat," contrasting with the centering diphthong /əʊ/ of southern and reflecting older Scots vowel systems. Wells (1982) documents this in volume 2 of Accents of English, highlighting how GOAT often aligns with a low-mid back monophthong in , influenced by Lowland Scots . Limited extensions to consonants occur via the R-set, where rhoticity—postvocalic [ɹ] or approximant [ɻ]—marks rhotic dialects in , distinguishing it from non-rhotic southern varieties; Wells notes this affects sets like NURSE and lettER, rendering them as [ɜɹ] or [əɹ]. Wells's methodology has inspired applications to other languages for phonetic descriptions, particularly in comparing Celtic substrate effects on English varieties. Wells (1982) references these influences in contextualizing Irish and Scottish accents, prioritizing high-impact contrasts over exhaustive listings.

Recent Developments and Limitations

Since the , happy tensing has emerged as a widespread innovation in many English accents, particularly in , where the in the happY lexical set has shifted from a lax [ɪ] to a tense [iː] realization, reflecting broader phonetic trends toward lengthening in unstressed syllables. This change, first noted as an increasing tendency by John Wells in the late , has become a near-standard feature in contemporary and other urban British varieties, as evidenced by acoustic analyses of public figures' speech over decades. Wells himself revisited the phenomenon in his 2012 blog post, advocating for the phonetic symbol /i/ to represent this tensing in weak syllables, underscoring its stabilization across English-speaking communities. As of 2023, computational tools have begun integrating lexical sets for automated analysis of happy tensing in large speech corpora. Proposals for expanding the lexical set framework have addressed evolving phonological mergers, such as the Mary–merry–marry merger prevalent in General American, where distinct pre-rhotic vowels in words like Mary (/eər/), merry (/ɛr/), and marry (/ær/) converge into a single category, necessitating additional sets to capture regional variability. In his 2010s writings, including blog entries, Wells reflected on the original sets' foundations in RP and General American, suggesting refinements to accommodate such mergers and allophonic variations without altering the core system. More recent scholarship has proposed broader extensions to include , incorporating sets for non-standard vowel qualities in postcolonial varieties like Indian or , thereby adapting the framework to global diversity. Despite these advances, the lexical set system exhibits limitations rooted in its origins, primarily focusing on RP and General American as reference accents, which underrepresents the phonological richness of global Englishes and peripheral dialects. It primarily targets vowels, offering little guidance for variations or suprasegmental features like intonation and , which are crucial in dialectal differentiation and often overlooked in set-based analyses. Critics have highlighted its potential oversimplification for complex dialects, where intricate mergers or split systems—such as those involving multiple rhotics—defy neat categorization into predefined sets, limiting applicability in fine-grained sociophonetic studies. Looking ahead, integrating lexical sets with promises dynamic updates, enabling real-time tracking of phonological shifts through large-scale annotated datasets that map set keywords to contemporary speech . Projects like the Eighteenth-Century database exemplify this approach by aligning Wells' sets with historical for empirical validation, paving the way for ongoing revisions that reflect language evolution in diverse contexts.
