'accoutre' originates from Middle French, specifically the word 'accoutrer,' where 'a-' meant 'to' and 'couter' meant 'sew.'

'accoutrer' transformed into the English word 'accoutre,' and eventually became the modern English word 'accoutre' through Middle English.

Initially, it meant 'to sew or stitch together,' but over time it evolved into its current meaning of 'to equip or outfit.'
