need (n.) Old English nied (West Saxon), ned (Mercian) "necessity, compulsion, duty; hardship, distress; errand, business," originally "violence, force," from Proto-Germanic *nauthiz/*naudiz (source also of Old Saxon nod, Old Norse nauðr, Old Frisian ned, Middle Dutch, Dutch nood, Old High German not, German Not, Gothic nauþs "need"), probably cognate with Old Prussian nautin "need," and perhaps with Old Church Slavonic nazda, Russian nuzda, Polish nędza "misery, distress," from PIE *nau- (1) "death, to be exhausted" (see narwhal).
need (v.) Old English neodian "be necessary, be required (for some purpose); require, have need of," from the same root as need (n.). Meaning "to be under obligation (to do something)" is from late 14c. Related: Needed; needing. The adjectival phrase need-to-know is attested from 1952. Dismissive phrase who needs it?, popular from c. 1960, is a translated Yiddishism.
