means A heavy, early matchlock firearm fired from a support or braced against the body, the forerunner of the musket.

from From Middle French 'arquebuse', itself an alteration of the Middle Dutch 'hakebusse' — literally 'hook gun' (haak, hook + busse, box/gun barrel), likely named for a hook on the barrel used to brace the weapon against a wall or rest when firing. The word traveled through French and Italian forms, picking up the misleading 'arc' (bow) spelling along the way by folk association, before settling into English as 'arquebus'.
