Word Nuance & Usage

'Compact' is a heteronym whose stress shifts by part of speech and meaning: the noun (whether meaning a formal agreement or a cosmetic case) and the common adjective (meaning small and efficiently designed) are stressed on the first syllable (KOM-pakt), whereas the verb and formal predicative adjective uses are typically stressed on the second syllable (kuhm-PAKT).

Word Origin & Etymology

This word represents two distinct Latin roots that converged in spelling: the sense of 'closely packed' and the verb 'to compress' come from Latin compactus, the past participle of compingere ('to fasten together'), while the noun meaning 'a formal agreement' derives from Latin compactum, from compacisci ('to make an agreement with').
