Word Origin & History
whileO.E. hwile, acc. of hwil "a space of time," from P.Gmc. *khwilo (cf. O.S. hwil, O.Fris. hwile, O.H.G. hwila, Ger. Weile, Goth. hveila "space of time, while"), originally "rest" (cf. O.N. hvila "bed," hvild "rest"), from PIE *qwi- "rest" (cf. Avestan shaitish "joy," O.Pers. iyatish "joy," L. quies "rest,
repose, quiet," O.C.S. po-koji "rest"). Notion of "period of rest" became in Gmc. "period of time." Now largely superseded by
time except in formulaic constructions (e.g. all the while). M.E. sense of "time spent in doing something" now only preserved in
worthwhile and phrases such as worth (one's) while. As a conjunction (late O.E.), it represents O.E. þa hwile þe; form whiles is recorded from c.1220; whilst is from c.1375, with excrescent -st as in amongst, amidst (see
amid).
while"to cause (time) to pass without dullness, 1635, earlier "to occupy or engage (someone or something) for a period of time" (1606), new formation from
while (n.), not considered to be from M.E. hwulen "to have leisure," which is from a Gmc. verb form of
while (n.) (cf. Ger. weilen "to stay, linger"). An association with phrases such as Shakespearean beguile the day, L. diem decipere, Fr. tromper le temps "has led to the substitution of WILE v by some modern writers" [OED] (see
wile).
