assured
UK: əˈʃʊəd | US: əˈʃʊrd
adj. confident in one's abilities or qualities
adj. guaranteed; certain to happen
vt. (past tense of assure) made someone confident or certain
The word assured originates from the Old French aseürer (to reassure, secure), derived from Latin ad- (toward) + securus (safe, certain). The prefix as- (variant of ad-) intensifies the root sure, which stems from Latin securus. Over time, assured evolved to mean both "made certain" (verb) and "confident/guaranteed" (adjective), reflecting its dual role in English.
