Origin of the word
The verb endeavour dates from around the 14th century and is derived from the phrase ‘put in dever’, where ‘dever’ represents ‘duty’ as in the Old French. This, in turn, was taken from the Latin ‘debere’ meaning ‘to owe’, while the original definition was ‘to take something away from someone’.
The Old French root in the early 15th century led to the formation of endeavour as a noun. The phrase ‘mettre en deveir’ meant to ‘put in duty’ or to ‘make it one’s duty.’ From this the meaning shifted to ‘taking pains to attain something’ and by the late 15th century this was equivalent to ‘making the greatest effort’.
