"relating to a hospital," 1849 (earlier in German and French), from Late Latin nosocomium, from Greek nosokomeion "an infirmary," from nosokomein "to take care of the sick," from nosos "disease, sickness," a word of unknown origin, + komein "take care of, attend to." Nosocome was a 17c. word for "hospital."
early 14c. as a verbal phrase, "lift and take with the fingers," from pick (v.) + up (adv.). From 1510s as "take or get casually, obtain or procure as opportunity offers." Meaning "take (a person found or overtaken) into a vehicle or vessel," is from 1690s, also, of persons, "make acquaintance or take along" (especially for sexual purposes). Intransitive meaning "improve gradually, reacquire vigor or strength" is by 1741. Sense of "tidy up" is from 1861; that of "arrest" is from 1871; meaning "gain speed" is from 1922; meaning "to pay" (a check, tab, etc.) is from 1945. Pick-me-up "stimulating alcoholic drink" is attested from 1867.
c. 1400, nome, "deprived of motion or feeling, powerless to feel or act," literally "taken, seized," from past participle of nimen "to take, seize," from Old English niman "to take, catch, grasp" (from PIE root *nem- "assign, allot; take"). The unetymological -b (to conform to comb, limb, etc.) appeared 17c. The notion is of being "taken" with palsy, shock, and especially cold. Figurative use is from 1560s.
c. 1300, receiven, "take into one's possession, accept possession of," also in reference to the sacrament, from Old North French receivre (Old French recoivre) "seize, take hold of, pick up; welcome, accept," from Latin recipere "regain, take back, bring back, carry back, recover; take to oneself, take in, admit," from re- "back," though the exact sense here is obscure (see re-) + -cipere, combining form of capere "to take" (from PIE root *kap- "to grasp").
From c. 1300 as "welcome (in a specified manner)." From early 14c. as "catch in the manner of a receptacle." From mid-14c. as "obtain as one's reward." From late 14c. as "accept as authoritative or true;" also late 14c. as "have a blow or wound inflicted." Radio and (later) television sense is attested from 1908. Related: Received; receiving. Receiving line is by 1933.
