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.
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. 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".
Lexical sets, as defined in Wells (1982), pp. xviii–ix, 120–2, 166–7The 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/.
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. 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. Wells's model of General American is also conservative in that it lacks the cot–caught (LOT–THOUGHT) and horse–hoarse (NORTH–FORCE) mergers.
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⟩).
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": Thus, for example, in describing the Newfoundland accent, Wells writes that "KIT and DRESS are reportedly often merged as [ɪ]", 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.
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".
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.
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 or in south-east London. 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.
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:
