cutlass: [16] Appropriate as the name sounds, cutlass has no etymological connection with cut. It comes from Old French cutelas, a derivative (denoting large size) of coutel ‘knife’. This in turn goes back to Latin cultellus, a diminutive of culter ‘knife, ploughshare’ (source of English coulter [OE] and cutler [14], whence cutlery [14]).
