lounge (v.) Look up lounge at Dictionary.com
c. 1500, "to loll idly, act or rest lazily and indifferently, move indolently if at all," Scottish, a word of uncertain origin. Meaning "recline lazily" is from 1746. Perhaps [Barnhart] it is from French s'allonger (paresseusement) "to lounge about, lie at full length," from Old French alongier "lengthen," from Latin longus "long" (see long (adj.)).

Another etymology traces it through the obsolete noun lungis "slow, lazy person" (c. 1560), which is from French longis "an idle, stupid dreamer," a special application, for some obscure reason, in Old French of the proper name Longis, which is from Latin Longius, Longinus. In old mystery plays and apocryphal gospels, Longinus is the name of the centurion who pierces Christ's side with a spear; the name perhaps was suggested by Greek longe "a lance" in John xix.34. But popular etymology associated the name directly with long (adj.). Related: Lounged; lounging; lounger.

1540s, "awkward fellow, boor, bumpkin," of uncertain origin. Perhaps a noun from a dialectal survival of Middle English louten (v.)

According to Watkins this is from PIE *leud- "to lurk" (source also of Gothic luton "to deceive," Old English lot "deceit), also "to be small" (see little).

Skeat and Klein's sources suggest it is from French l'ouvert, literally "the open place," from le, definite article, + past participle of ouvrir "to open." Century Dictionary finds this "quite untenable."

Meaning "overlapping strips in a window" (to let in air but keep out rain) first recorded 1550s.

But soon we shall die and all memory of those five will have left the earth, and we ourselves shall be loved for a while and forgotten. But the love will have been enough; all those impulses of love return the love that made them. Even memory is not necessary for love.
