improvised
UK: ˈɪmprəvaɪzd | US: ˈɪmprəvaɪzd
adj. created or performed spontaneously without preparation
vt. (past tense of improvise) to create or perform something spontaneously
The word "improvised" originates from the Latin improvisus, meaning "unforeseen," combining im- (not) + provisus (provided/foreseen). The root provis- comes from providere (to foresee or supply). Over time, it evolved through Italian improvvisare and French improviser to mean creating something spontaneously without prior planning. The suffix -ed marks it as a past participle, indicating a completed action.
