(as a verb in the sense 'dig a sap or covered trench'): from French saper, from Italian zappare, from zappa 'spade, spadework', probably from Arabic sarab 'underground passage', or sabora 'probe a wound, explore'early 19th cent.: abbreviation of dialect sapskull 'person with a head like sapwood', from sap (in the sense 'sapwood') + skulllate 19th cent.
