A serious attempt or effort to achieve something, especially something difficult or challenging. The British spelling of 'endeavor,' often used to suggest noble or ambitious undertakings.
From Middle English 'endeveren,' meaning 'to exert oneself.' Literally 'put oneself in duty,' from 'en-' (in) plus 'devoir' (duty, from French). The spelling with 'ou' reflects British orthographic conventions.
The word 'endeavour' carries a sense of noble struggle that's missing from simpler words like 'try' - it suggests both great effort and worthy purpose! Captain Cook's ship was named Endeavour, perfectly capturing the spirit of ambitious exploration.
