More about olericulture
Starting from the end, the –iculture of olericulture “cultivation of vegetables for the home or market” is familiar to us from compounds like agriculture “the cultivation of land for crops,” and the relatively recent apiculture “beekeeping, especially commercial beekeeping.” The first part of olericulture comes from oleri-, the inflectional stem of the Latin noun olus (also holus) “a vegetable, vegetables, kitchen herb,” which is related to the adjective helvus “yellowish, dun (of cattle).” Helvus is the Latin result of the Proto-Indo-European adjective ghelwos “bright, yellow,” a derivative of the Proto-Indo-European root ghel– “to shine,” a root that is particularly associated with colors. Latin has another adjective gilvus “yellowish” (used of domestic animals), a borrowing from a Celtic language. Much, much closer to home, ghelwos becomes gelwa– in the Germanic languages, the source of English yellow. Olericulture entered English in the second half of the 19th century.
