Etymology: Ancient Romans knew this plant as "allium," and the word itself is older than the Latin naming of the genus. The genus name was later taken up by Carl Linnaeus, the Swedish botanist whose system still organizes living things, so the word that once described garlic and onions in a Roman kitchen now serves as the scientific label for the whole group, including chives, leeks and shallots. The plant's common name in English has a different path. Garlic and onions are old, familiar foods, and their English names are native words, which means the scientific term is the outsider here. Most English speakers meet "allium" only in a garden catalogue or on a seed packet, where it names the ornamental flowers with globe-shaped purple heads, a relative of the kitchen onion grown for show.
