'arrivance' originates from Old French, specifically the word 'arriver', where 'arriver' meant 'to arrive' or 'come to land'.

'arrivance' changed from the Middle English word 'arrivaunce' (borrowed from Old French) and eventually became the modern English word 'arrivance' as an archaic/obsolete noun meaning 'arrival'.

Initially, it meant 'the act or process of arriving (often of ships coming to shore)', but over time it narrowed/shifted to a general (now archaic) sense of 'arrival'.
