'venture' originates from Old French, specifically the word 'aventure', where the element came from Latin 'advent-' (from 'advenire') meaning 'to come' (with sense of 'chance' or 'what happens').

'venture' changed from Old French 'aventure' into Middle English 'aventure' (also spelled 'venture'), and eventually became the modern English word 'venture'.

Initially it meant 'chance' or 'what happens by chance', but over time it evolved into the modern sense of 'a risky undertaking' and the verb sense 'to take a risk'.
