Etymology

From Middle English onyoun, oynoun, from Old French oignon, from Latin ūniōnem, accusative of ūniō (“onion”), which had also been borrowed into Old English as yne, ynnelēac (“onion”) (> Middle English hynne-leac, henne-leac). Displaced the inherited term ramsons. * (soy): Stems from a 4chan word filter which changes the word soy to onions. The word filter was implemented in relation to the "alpha onion eater" meme, which is depicted as the direct opposite of the soy boy.
