Affixation is a morphological process in which a language attaches a bound morpheme — a prefix, suffix, or circumfix — to the edge of a word stem to produce a new word. Three parameters carve the construct: (1) the attached material is a bound morpheme, not an independent word, and it attaches at the stem's edge, not inside it, separating affixation from infixation and tmesis; (2) the host stem retains its lexical identity and the affixed form remains analyzable as stem plus affix; (3) the operation is rule-governed in a given language — which affixes exist, where they attach, and what meaning they contribute are parameters of the grammar, not free invention. Paradigmatic cases: English un-happy, cat-s, re-do; Arabic prefixation a-...; German circumfix ge-...-t. Affixation persists two ways: as a productive rule — speakers coin new affixed forms on the fly — and as a stable category of description — grammars, morphology textbooks, and formal rule specifications continue to state which affixes attach where and what they mark.

Definition
Why it is in scope
Affixation is a human-made morphological category — the process by which a language attaches a bound morpheme to the edge of a word stem — built to persist as the stable classification catalogued in the grammars of the languages that have it and taught in morphology curricula.

Relations from this entry
- stemDEPENDS_ON →
Pinned sense: affixation as the process attaching a bound morpheme to a word stem (its accepted definition's own parameter 1 names the stem as the host). Removal test (Laws 2b/8b): remove stems — the host material affixation attaches to — and there is nothing left to attach an affix to; the process stops operating. Constitutive dependency on the host material, the same process-to-material pattern as affixation DEP affix.
- word-formationINSTANCE_OF →
Nearest-kind test, pinned sense: the word-formation genus. Word-formation carves the made category of processes producing new words from existing lexical material, and its own definition names affixation among its members ('affixation (attaching bound morphemes to a stem)'). Affixation passes all three genus parameters: existing lexical material in (stem plus bound morpheme), a new word out (un-happy, cat-s), rule-governed in each language. No accepted intermediate kind stands between affixation and word-formation on the board; specific-to-general holds.
- morphemeDEPENDS_ON →
Pinned sense (Law 11d): affixation as the process of attaching bound morphemes to stems. DEPENDS_ON test: remove morphemes — the units that affixation manipulates — and the process collapses. Affixation operates on bound morphemes; without them there is nothing to attach. Constitutive dependency per Laws 8/8b.
- affixDEPENDS_ON →
affixation DEPENDS_ON affix: affixation is the process of attaching affixes to word stems. Remove affixes — the objects that affixation manipulates — and the process cannot operate. Constitutive dependency.

- infixation← INSTANCE_OF
Infixation is the specific process of inserting a morpheme within the interior of a word stem. It is a subtype of affixation — the nearest kind is affixation: a competent speaker classifies infixation as a kind of affixation.
