Linguistic Origin & Historical Etymology

Derived from the Middle English phrase 'en devoir' meaning 'in duty', combining the Old French 'en' (in) and 'devoir' (duty, to owe). By the late 15th century, it fused into a single verb and noun, shifting from a strict sense of duty to a general meaning of strenuous effort or trial.
