lock
{{11}}lock (n.1) "means of fastening," O.E. loc "bolt, fastening; barrier, enclosure," from P.Gmc. *lukan (Cf. O.N. lok "fastening, lock," Goth. usluks "opening," O.H.G. loh "dungeon," Ger. Loch "opening, hole," Du. luik "shutter, trapdoor"). "The great diversity of meaning in the Teut. words seems to indicate two or more independent but formally identical substantival formations from the root." The O.E. sense "barrier, enclosure" led to the specific meaning "barrier on a river" (c.1300), and the more specific sense "gate and sluice system on a water channel used as a means of raising and lowering boats" (1570s). Wrestling sense is from c.1600. Phrase under lock and key attested from early 14c.
{{12}}lock (n.2) "tress of hair," O.E. locc "lock of hair, curl," from P.Gmc. *lukkoz (Cf. O.N. lokkr, O.S., O.Fris., Du. lok, O.H.G. loc, Ger. Locke "lock of hair"), from PIE *lugnos-, perhaps related to Gk. lygos "pliant twig, withe," Lith. lugnas "flexible."
{{12}}lock (v.) "to fasten with a lock," c.1300, from O.E. lucan "to lock, to close" (class II strong verb; past tense leac, pp. locen), from the same root as LOCK (Cf. lock) (n.1). Cognate with O.Fris. luka "to close," O.S. lukan, O.H.G. luhhan, O.N. luka, Goth. galukan. Meaning "to embrace closely" is from 1610s. Related: Locked; locking. Slang lock horns "fight" is from 1839.
