vainglory

From Middle English waynglori (“worthless glory”), from Old French vaine glorie, from Medieval Latin vāna glōria, from Latin vāna (“empty, groundless, boastful”) + glōria (“fame, ambition, boasting”), apparently modelled after similar terms in Germanic languages. Compare Old English īdel wuldor (“vain glory”) and īdelġielp (“vainglory”).
