'aunter' originates from Old French, specifically the word 'aventure', where the prefix 'a-' (from Latin 'ad-') meant 'to' and the root (from Latin 'ventura/vent-') related to 'that which happens' or 'an event'.

'aunter' changed from Old French word 'aventure' and Middle English forms such as 'aventur'/'aunter' and eventually existed in English as the archaic/ dialectal form 'aunter' (related to modern 'adventure').

Initially, it meant 'that which happens; an event or occurrence', but over time it evolved toward the sense 'adventure; a risky undertaking' and today survives only as an archaic or dialectal term.
