Repose is a formal or literary term used to mean the act of resting, or the state of being at rest. Repose is also a state of mind: freedom from worry. As a verb, repose means to rest or relax, or to rest on something for support: There she was, reposing on the front porch. The verb is from Middle English, from Old French reposer, from Late Latin repausÄre to cause to rest, from the Latin prefix re- again plus pausÄre to rest..
Figurative use for repose of death was in Old English; to put (an animal) to sleep kill painlessly is recorded from 1923 (a similar imagery is in cemetery). Sleep deprivation attested from 1906. Sleep-walker somnambulist is attested from 1747; sleep-walking is from 1840.
