sleep

{{11}}sleep (n.) O.E. slæp from the root of SLEEP (Cf. sleep) (v.); Cf. cognate O.S. slap, O.Fris. slep, M.Du. slæp, Du. slaap, O.H.G. slaf, Ger. Schlaf, Goth. sleps.
Personified in Latin as Somnus, in Greek as Hypnos (see SOMNOLENCE (Cf. somnolence)). Figurative use for "repose of death" was in Old English; to put (an animal) to sleep "kill painlessly" is recorded from 1923. Sleep deprivation attested from 1906. Sleep-walker "somnambulist" is attested from 1747. To be able to do something in (one's) sleep "easily" is recorded from 1953.
{{12}}sleep (v.) O.E. slæpan "to sleep" (class VII strong verb; past tense slep, pp. slæpen), from W.Gmc. *slæpanan (Cf. O.S. slapan, O.Fris. slepa, M.Du. slapen, Du. slapen, O.H.G. slafen, Ger. schlafen, Goth. slepan "to sleep"), from PIE root *sleb- "to be weak, sleep" (Cf. O.C.S. slabu, Lith. silpnas "weak"), which is perhaps connected to the root of SLACK (Cf. slack) (adj.). Sleep with "do the sex act with" is in Old English.
Gif hwa fæmnan beswice unbeweddode, and hire mid slæpe ... [Laws of King Alfred, c.900]
Sleep around first attested 1928. Sleeping sickness as a specific African tropical disease is first recorded 1875.
