It and its Greek relative neuron (source of English neural) may belong to a wider family of words that includes Latin nēre ‘spin’ (a relative of English needle) and possibly also English narrow, perhaps with a common meaning element. The application to ‘bundle of fibres carrying sensory or other impulses’ seems to have begun in Greek, but was soon adopted into the Latin word, and was brought with it into English.Metaphorically, the Romans used nervus for ‘strength, force’, an application perhaps lying behind the English sense ‘courage’, first recorded in the early 19th century. The use of the plural nerves for ‘agitation, apprehension’ (and of the adjective nervous [14] for ‘apprehensive’) is an English development, which probably started in the mid- 18th century.=> needle, neuralnerve (n.)late 14c., nerf "sinew, tendon," from Old French nerf and directly from Medieval Latin nervus "nerve," from Latin nervus "sinew, tendon; cord, bowstring," metathesis of pre-Latin *neuros, from PIE *(s)neu- "tendon, sinew" (cognates: Sanskrit snavan- "band, sinew," Armenian neard "sinew," Greek neuron "sinew, tendon," in Galen "nerve"). Sense of "fibers that convey impulses between the brain and the body" is from c. 1600. Secondary senses developed from meaning "strength, vigor, energy" (c. 1600), from the "sinew" sense. Hence figurative sense of "feeling, courage," first attested c. 1600; that of "courage, boldness" is from 1809; bad sense "impudence, cheek" is from 1887. Latin nervus also had a figurative sense of "vigor, force, power, strength," as did Greek neuron. From the neurological sense come Nerves "condition of nervousness," attested from 1792; to get on someone's nerves, from 1895. War of nerves "psychological warfare" is from 1915.nerve (v.)c. 1500, "to ornament with threads;" see nerve (n.). Meaning "to give strength or vigor" is from 1749. Related: Nerved; nerving." |
