英文词源

lack: lack: [12] The word lack is not known to have existed in Old English, although it is by no means impossible that it did. If it was a borrowing, a possible source would have been Middle Dutch lak ‘deficiency, fault’. This has been traced back to a prehistoric Germanic *lak-, a variant of which produced English leak.
=> leak
lack (n.): c. 1300, "absence, want; shortage, deficiency," perhaps from an unrecorded Old English *lac, or else borrowed from Middle Dutch lak "deficiency, fault;" in either case from Proto-Germanic *laka- (cognates: Old Frisian lek "disadvantage, damage," Old Norse lakr "lacking"), from PIE *leg- "to dribble, trickle" (see leak (v.)). Middle English also had lackless "without blame or fault."
lack (v.): late 12c., perhaps from Middle Dutch laken "to be wanting," from lak (n.) "deficiency, fault," or an unrecorded native cognate word (see lack (n.)). Related: Lacked; lacking.
