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

'accoutrer' transformed into the English word 'accoutre,' and eventually became the modern English word 'accoutred' as its past participle form.

Initially, it meant 'to equip or dress,' and this meaning has largely remained the same in modern usage.
