Morphology is a human-made discipline of linguistics that studies the internal structure of words and the systematic relations among word-forms. Three parameters carve the construct: (1) domain: the object is the word as a structured unit — the decomposition of word-forms into morphemes (the morpheme system) and the processes that combine, inflect, or derive words into new words (word-formation); the domain's boundary is the word itself — relations between words belong to syntax, sound structure to phonology; (2) method: analysis proceeds by isolating the minimal meaningful units of a language, classifying them as free or bound, and describing the paradigmatic relations (inflectional paradigms, derivational families) that hold among word-forms; (3) codification: findings are fixed as grammatical description — inventories of affixes, paradigm tables, word-formation rules — which differ per language but share a stable form. Morphology persists as a discipline: it is taught as a field of linguistics, its categories (morpheme, affix, stem, root, paradigm) form the stable vocabulary of grammatical description across languages, and its methods are operationalized in dictionaries, morphological analyzers, and language documentation.

Definition
Why it is in scope
Morphology is a human-made discipline of linguistics — the field that studies the internal structure of words and the systematic relations among word-forms — built to persist as a stable field of analysis in grammatical description, academic teaching, and computational linguistics.

Morphology studies the structure of lexemes — removing lexemes leaves morphology without its subject matter; it cannot operate on word structure where there are no lexemes.
- compoundingCONTAINS →
Compounding is a constituent process within the morphological system — combining two or more independent lexemes to form a single new word.
- inflectionCONTAINS →
Inflection is a constituent process within the morphological system — alongside derivation and compounding, it is one of the primary operations by which morphology builds and transforms word structure. Whole→part: inflection is a part of morphology's domain of study.
- cmrppet0d07qjd1nlnduesf5iCONTAINS →
Tmesis is a constituent process within the morphological system — the operation of inserting a grammatically independent element into a word's interior. Per the morphology definition, the discipline's domain includes the processes of word-formation; the word-formation definition names tmesis among its members. Whole→part: tmesis is a part of morphology's domain of study.
- infixationCONTAINS →
Infixation is a constituent process within the morphological system — the operation of inserting a bound morpheme into a stem's interior. Per the morphology definition, the discipline's domain includes the processes of word-formation; the word-formation definition names infixation among its members. Whole→part: infixation is a part of morphology's domain of study.

DEPENDS_ON removal test (Law 8): morphology is the discipline studying word structure, morpheme systems, inflection, and word-formation — all of which are properties of languages. Remove language and morphology has no subject matter, no data, no domain to operate on. It ceases to function as a discipline. Pinned sense: morphology as the linguistic discipline of word-structure analysis.
- derivationCONTAINS →
Derivation is a constituent process within the morphological system — alongside inflection, it is one of the primary operations by which morphology builds and transforms word structure.
- affixationCONTAINS →
Affixation is a constituent operation within the morphological system — the process of attaching affixes to stems to create new words or modify existing ones.
- linguisticsINSTANCE_OF →
Subfield→parent, the board's accepted pattern (audio-engineering INSTANCE_OF engineering). Morphology's accepted definition carves it as 'a human-made discipline of linguistics' — the word is in the carving: it is a discipline OF linguistics, one of the named subdisciplines (with phonology, syntax, semantics, pragmatics, historical linguistics). Nearest accepted kind: linguistics is the discipline of which morphology is a named subdivision; there is no intermediate accepted kind between them. Pinned sense: morphology as the discipline of word-structure analysis, filed against its parent discipline.
