Word Origin & History

"body of water," c.1200, from O.Fr. lack, from L. lacus "pond, lake," also "basin, tank," related to lacuna "hole, pit," from PIE *lak- (cf. Gk. lakkos "pit, tank, pond," O.C.S. loky "pool, puddle, cistern," O.Ir. loch "lake, pond"). The common notion is "basin." There was a Gmc. form of the word, which
yielded cognate O.N. lögr "sea flood, water," O.E. lacu "stream," lagu "sea flood, water," leccan "to moisten" (see leak). The N.Amer. Great Lakes so called from 1660s. Laker "boat made for sailing on the Great Lakes" is from 1887.

"deep red coloring matter," 1616, from Fr. laque (see lac), from which it was obtained.
