1. reserved, modest, and shy (typically used of a woman): "a demure young lady"
▪ (of clothing) giving a modest appearance:"a demure knee-length skirt"
Word Originlate Middle English (in the sense ‘sober, serious, reserved’): perhaps from Old French demoure, past participle of demourer ‘remain’ (see demur); influenced by Old French mur ‘grave’, from Latin maturus ‘ripe or mature’. The sense ‘reserved, shy’ dates from the late 17th century.
