acquaint: [13] Acquaint is connected with quaint, distant though they may seem in meaning. It comes via Old French acointer from medieval Latin accognitāre, which was based ultimately on cognitus, the past participle of cognoscere ‘know’. Cognitus gave English cognition, of course, but also quaint (cognitus developed into cointe, queinte in Old French, and came to mean ‘skilled, expert’; this led later to the notion of being skilfully made or elegant, which eventually degenerated into ‘agreeably curious’).
