Word formation is the made category comprising the processes by which a language's speakers produce new words from existing lexical material. Three parameters carve the construct: (1) the input is existing lexical material of the language — stems, morphemes, or whole words — which separates word formation from borrowing (which introduces material from another language) and from one-off coinage by a single act of naming; (2) the output is a new word — a new lexical item entering the language's inventory, not a new phrase, sentence, or mere variant of an existing word; (3) the operations are rule-governed in a given language: each language has its own available operations and their combinations, so which formations are possible is a parameter of the grammar, not free invention. Its members include compounding (juxtaposing free morphemes into a single word), affixation (attaching bound morphemes to a stem), infixation (inserting a bound morpheme into a stem's interior), and tmesis (inserting a grammatically independent element into a word's interior); the board's entries for those operations are instances of this genus. Paradigmatic cases: English blackboard (compounding), English -ness (suffixation), Tagalog -um- (infixation: kain 'eat' to k-um-in), fan-frickin'-tastic (tmesis). Word formation persists as a category of grammatical description: its operations are catalogued in the grammars and dictionaries of each language, taught as a stable classification in linguistics, and applied productively by speakers who coin new words.

Definition
Why it is in scope
Word formation is a human-made morphological category — the genus comprising the processes by which a language's speakers produce new words from existing lexical material — built to persist as the stable classification under which particular operations (compounding, affixation, infixation, tmesis) are catalogued in the grammars of the languages that use them.

Word-formation is the process of creating new words within a language system. Remove language and word-formation has no system to operate on — it ceases to function. Pinned sense: word-formation as a linguistic process, not as a general concept of creation.
Relations to this entry
- compounding← INSTANCE_OF
Pinned sense: compounding as the process of juxtaposing free morphemes into a single new word. That is a specific word-formation process under the word-formation carve: existing lexical material in (two or more free morphemes), a new word out (the compound), rule-governed in each language. The board's own word-formation definition names compounding among its members. Nearest-kind: no accepted kind interposes between compounding and word-formation on the board; specific-to-general holds.
- affixation← INSTANCE_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.
- cmrppet0d07qjd1nlnduesf5i← INSTANCE_OF
Pinned sense (the surviving holder's accepted definition): tmesis as the operation of inserting grammatically independent material into a word's interior. That is a specific word-formation process under the word-formation carve: existing lexical material in (the host word), a new word form out (the split form), conventional/rule-governed in the speech community. The board's own word-formation definition names tmesis among its members. Nearest-kind: no accepted kind interposes between tmesis and word-formation — the holder's accepted INSTANCE_OF to figure-of-speech pins the EXPRESSIVE sense (a rhetorical figure) and does not stand in the word-formation ladder; the two edges carry different senses and both may stand (Law 11d).
- infixation← INSTANCE_OF
INSTANCE_OF: infixation is a specific kind of word-formation process — the general class into which tmesis is also an instance. Specific→general per Law 9.
