Lexical set¶
A lexical set is a group of words that share a particular vowel or consonant sound.
Core Idea¶
Lexical set is treated here as the recurring lexical semantics identity summarized by this source-grounded definition: A lexical set is a group of words that share a particular vowel or consonant sound. 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.
Scope of Application¶
-
Usage. 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.
-
Usage. 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.
-
Usage. Lexical sets may also be used to describe splits and mergers.
-
Documented setting. Lexical sets have also been used to describe the vowels of other languages, such as French, Irish and Scots.
-
Standard lexical sets for English. Wells defined each lexical set on the basis of the pronunciation of words in two reference accents, which he calls RP and GenAm.
Clarity¶
A clear use of Lexical set names the carrier, the operative relation, and the conditions under which the source treats the identity as present. The minimal definition is A lexical set is a group of words that share a particular vowel or consonant sound. The strongest recognition evidence in the frozen account is: Wells has stated that he didn't include a set because this should be interpreted as an allophone.
Manages Complexity¶
Lexical set compresses multiple lexical semantics details into a stable diagnostic relation. The source shows both the central mechanism—the notation for happ has since emerged and been taken up by major pronouncing dictionaries, including Wells's, to take note of this shift.—and the practical consequence—originally, Wells developed 24 such labels—keywords—for the vowel lexical sets of English, which have been sometimes modified and expanded by himself or.
Abstract Reasoning¶
- Type the carrier. Identify the lexical semantics entities to which the claim applies.
- State the relation. Use the source-grounded identity: A lexical set is a group of words that share a particular vowel or consonant sound.
- Check operation and conditions. Some varieties of English make distinctions in stressed vowels that are not captured by the 24 lexical sets.
- Demand recognition evidence.
Knowledge Transfer¶
Within the home domain. Knowledge about Lexical set transfers literally when a new case preserves the same carrier type, relation, and recognition test. 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. 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 " and are reportedly often merged as ", meaning that the stressed syllables of words.
Neighborhood in Abstraction Space¶
Lexical set sits in a sparse region of the domain-specific corpus (71st percentile for distinctiveness): few abstractions share its structure, so a faithful description tends to retrieve it precisely.
