Forms
oignon m (plural oignons)[1] Old French unniun (about 1190), hunion (about 1200), oingnun (1260), ognon (1275); oignon from 1332.[2][3]
Etymology
It is inherited from Old French unniun, inherited from Latin ūniō (“a kind of onion without cloves”) (accusative ūniōnem).[4][2][5][1][6] In Latin it was a dialect word, given by Columella, beside the usual caepa, the source of cive.[4][2][5] In imperial Latin the word meant chiefly a large pearl, and it is linked with ūnus (“one”) because the onion, unlike garlic, has a single bulb;[4][2][5] Rey notes that this may be a popular etymology.[4][2][5] The unstressed /u/ developed as in Old French jostise from justitia.[5]
The Latin word also passed into Germanic, giving Old English ynne, later replaced by English onion, which came from French through Anglo-Norman.[2] Most other Romance languages use descendants of Late Latin caepulla, such as Italian cipolla and Spanish cebolla.[5]
Earliest recorded meaning
An Old French glossary of about 1190 has unniun, the onion plant.[4][2]
Semantic evolution
Besides the plant and its bulb, from 1538 it named the bulb of other plants,[4][7] and by likeness of shape a painful swelling of the big toe (1611, oignon du pied; 1701), a large old-fashioned pocket watch (1834, in a popular song) and, in slang, the anus (1883).[4][2]
Il y a de l'oignon “there is something fishy” (1595) was still common in 19th-century slang.[2][4] Se mettre en rang d'oignon first meant to join a company where one does not belong (Cotgrave, 1611) and took its modern sense “in a single line” in 1654;[4][2] Rey sets aside the story of a baron d'Oignon who seated the deputies at Blois in 1576 as resting only on a homonymy.[4][2] Later came aux petits oignons “done with great care” (1855), from slow cooking with small onions, and c'est pas tes oignons (1922) and occupe-toi de tes oignons (1948).[4][2] Popular French clipped it to gnon “a blow” in the 19th century.[5]
