'bandage' originates from Middle English and Old French, specifically from Old French 'bandage' (from 'bander' meaning 'to bind'), with the suffix '-age' indicating an action or result.

'bandage' changed from Old French 'bandage' (from 'bander' 'to bind') into Middle English 'bandage' and eventually became the modern English word 'bandage'.

Initially, it referred to the action or result of binding; over time it evolved to refer specifically to a strip of material used to bind or cover a wound.
