Etymology

The word "endeavour" originates from Middle English endeveren, derived from the phrase put oneself in duty (en- + devoir). Devoir comes from Old French deveir (duty), tracing back to Latin dēbēre (to owe). The morpheme en- intensifies the sense of commitment, while deavour preserves the core idea of duty. Over time, the meaning shifted from "fulfilling an obligation" to "making a determined effort."
