To equip or outfit someone with clothing, armor, or gear, especially military equipment.
From French accoutrer, from Old French a coute (according to custom), or possibly a- + couture (sewing/dress). The term became standard in English by the 16th century for dressing soldiers.
Military texts from the 1600s use 'accouter' to describe the formal process of outfitting soldiers—it's a word that feels like it belongs in a period war novel, which is probably where you'll encounter it.
