Phonology is a human-made discipline of linguistics that studies the sound systems of languages: what sounds a language has, which of them are distinctive, and the rules governing how they combine, co-occur, and vary in speech. Three parameters carve the construct: (1) domain — the object is the sound structure of a language at and below the level of the word: the inventory of distinctive sound units (the phoneme system), their contextual variants (allophones), and the constraints and rules on their combinations (phonotactics, assimilation, stress, tone); the domain's boundaries are set by the level of analysis — the physical and perceptual description of speech sounds belongs to phonetics, the decomposition of words into morphemes belongs to morphology, and meaning belongs to semantics; (2) method — analysis proceeds by contrasting minimal pairs to isolate the distinctive units of a language, by describing the phonetic variants that surface in specific contexts, and by stating the rules that map an underlying representation onto its surface form; (3) codification — findings are fixed as phonemic inventories, phonotactic constraints, and rule statements that differ per language but share a stable descriptive form. Phonology persists as a discipline: it is taught as a field of linguistics, its categories (phoneme, allophone, phonotactics, stress, tone) form the stable vocabulary of grammatical description across languages, and its methods are operationalized in dictionaries, speech technology, and language documentation.

Definition
Why it is in scope
Phonology is a human-made discipline of linguistics — the field that inventories the distinctive sounds of a language and states the rules governing how those sounds combine, co-occur, and vary — built to persist as a stable field of analysis in grammatical description, language teaching, and speech technology.

Present-tense removal test (Laws 8, 8b); pinned sense: a discipline whose object of analysis is language. Remove language now — does phonology stop operating? Yes: per its accepted carve, phonology is the discipline that studies 'the sound systems of languages' — its object is language itself. Without language there is no sound system to inventory, no distinctive unit to isolate by minimal-pair contrast, no phonotactic constraint or phonological rule to state; the discipline's operations have nothing to operate on and the field ceases to operate. This is the same relation the board has already accepted for its sister disciplines: morphology DEPENDS_ON language, pragmatics DEPENDS_ON language, linguistics DEPENDS_ON language. Not DERIVED_FROM (no chronology claim is made), not SERVES (the discipline's operations are analysis, not service rendered for language's sake).

Specific to its nearest accepted kind (Laws 9, 11e); pinned sense: a discipline of linguistics. Phonology, per its accepted carve, is 'a human-made discipline of linguistics that studies the sound systems of languages' — one named subfield of the parent discipline, in exactly the relation the board's accepted siblings stand in: morphology, semantics, syntax, pragmatics, lexicography, and even phonetics each INSTANCE_OF linguistics. A competent linguist calls phonology 'a subfield of linguistics' — a specific kind of the general discipline, and linguistics is the nearest live kind (no finer accepted kind sits between subfield and parent). INSTANCE_OF, never CONTAINS: a subfield is a specific kind of the discipline, not a part contained in it.

- allophone← INSTANCE_OF
Allophone is a specific phonological category — the contextual variant of a phoneme. A competent phonologist calls an allophone 'a phonological unit', a specific kind of phonological category. Phonology per its accepted definition inventories phonemes and their allophones, so allophone is a specific instance of the general discipline's category. Nearest kind test satisfied: no accepted intermediate kind stands between allophone and phonology on the board; specific-to-general per Law 9.
