Origin: 1765–75; < Latin recumbent- (stem of recumbēns), present participle of recumbere to lie back, equivalent to re-re- + cumb-, akin to cubāre to lie down + -ent--ent
1642 (implied in recumbency), from L. recumbentem (nom. recumbens), prp. of recumbere "to recline," from re- "back" + -cumbere "to lie down," related to cubare "be lying" (see cubicle). A verb, recumb, has been attempted in Eng. occasionally since 1677.
