A horse, or something that resembles or is related to a horse; also used in fortification terms for structures related to defensive positions.
From Old French 'cheval,' derived from Latin 'caballus' (horse), the word entered English military and equestrian vocabulary and remains in various technical terms.
The word 'cheval' still lives in English in the term 'cheval glass' (a tall free-standing mirror)—called that because it was originally mounted on a stand that resembled a horse's shape, with four sturdy legs.
