compounding

Compounding is a word-formation process in which a language juxtaposes two or more free morphemes (independent words or lexical roots) into a single new word. Three parameters carve the construct: (1) the inputs are free morphemes — each retains its lexical identity and could function independently as a word in isolation; (2) the output is a single word, not a phrase: the compound exhibits phonological, syntactic, or morphological behavior as one unit (e.g., stress patterns, inflection on the final element only); (3) the semantic relationship between the constituents is governed by the grammar of the language — the compound does not simply mean the sum of its parts but establishes a conventionalized relationship (modification, possession, purpose, etc.). Paradigmatic cases: English blackboard (modifier-head), doghouse (purpose), swimwear (material-function). Compounding persists as a highly productive word-formation strategy across languages and as a stable category in lexical morphology and dictionary organization.
