II. sleep, v.|sliːp|
Pa. tense and pple. slept. Forms: (see below).
[OE. slápan, slǽpan, slépan (pa. tense slép, slépon, pa. pple. -slápen, etc.), = OFris. slêpa (WFris. sliepe, EFris. slepe, NFris. slêp, slîp), MDu. and Du. slapen, OS. slâpan (MLG. and LG. slapen), OHG. slâfan (MHG. slâfen, G. schlafen), Goth. slêpan (pa. tense saislêp, -zlêp, pa. pple. slêpans); wanting in Scandinavian. Besides the strong conjugation (with reduplicated pa. tense) OE. also had the weak forms slǽpte, slépte, and after the 14th cent. the strong conjugation disappears from the literary language. A similar change has taken place in WFris., where the pa. tense is now usually slepte, pa. pple. slept. The ME. slēped (mod.Sc. sleepit) may represent the northern OE. forms slépade, pl. slépedon (WS. inf. slápian).
It is possible that the weak forms slǽpte, slépte, properly belonged to a causative verb corresponding to MHG. (ent)- slæfen, older or dial. G. schläfen, although no trace of this usage appears in OE. texts. The infinitive of this would have had the form *slǽpan, Merc. and Angl. *slépan, and would consequently have been identical with the inf. of the strong verb, except where the latter had the special West Saxon form slápan. The strong pa. tense is frequent in ME., and the strong pa. pple. is occasionally found (cf. also aslopen); traces of strong conjugation appear in some mod. dialects, but it is possible that these are new formations.]
