'convoy' originates from the Old French word 'convoier', where 'con-' meant 'together' and 'voier' meant 'to go'.

'convoier' transformed into the Middle English word 'conveien', and eventually became the modern English word 'convoy'.

Initially, it meant 'to accompany on a journey', but over time it evolved into its current meaning of 'a group traveling together for protection'.
