- onion
- onion (n.) early 12c., from Anglo-Fr. union, O.Fr. oignon (formerly also oingnon), from L. unionem (nom. unio), colloquial rustic Roman for "a kind of onion," also "pearl" (via notion of a string of onions), lit. "one, unity;" sense connection is the successive layers of an onion, in contrast with garlic or cloves.Old English had ynne (in ynne-leac), from the same Latin source, which also produced Ir. inniun, Welsh wynwyn and similar words in Germanic. In Dutch, the ending in -n was mistaken for a plural inflection and new singular ui formed. The usual Indo-European name is represented by Gk. kromion, Ir. crem, Welsh craf, O.E. hramsa, Lith. kremuse. The usual Latin word was cepa, a loan from an unknown language; Cf. O.Fr. cive, O.E. cipe, and, via L.L. dim. cepulla, It. cipolla, Sp. cebolla, Pol. cebula. Ger. Zwiebel also is from this source, but altered by folk etymology in Old High German (zwibolla) from words for "two" and "ball." Onion ring is attested from 1952.Onions, the surname, is attested from mid-12c. (Ennian), from Old Wesh Enniaun, ultimately from L. Annianus, which was associated with Welsh einion "anvil."
