late (adj.) Look up late at Dictionary.com
O.E. læt "occurring after the customary or expected time," originally "slow, sluggish," from P.Gmc. *latas (cf. O.N. latr "sluggish, lazy," M.Du., O.S. lat, Ger. laß "idle, weary," Goth. lats "weary, sluggish, lazy," latjan "to hinder"), from PIE base *lad- "slow, weary" (cf. L. lassus "faint, weary, languid, exhausted," Gk. ledein "to be weary"). The sense of "deceased" (as in the late Mrs. Smith) is from 1490, from an adv. sense of "recently." Of women's menstrual periods, attested colloquially from 1962. Later "farewell" attested from 1954 in U.S. slang, short for see you later.
