ORIGIN
late Middle English (formerly also as ingage): from French engager, ultimately from the base of gage1. The word originally meant ‘to pawn or pledge something’, later ‘pledge oneself (to do something’), hence ‘enter into a contract’ (mid 16th century), ‘involve oneself in an activity’, ‘enter into combat’ (mid 17th century), giving rise to the notion ‘involve someone or something else’.
