Etymology: Opuntias is simply the plural of "opuntia", the name of the prickly pear genus. The genus name was given by Linnaeus and comes from Latin "Opuntia", itself drawn from "Opuntius", the adjective for Opus, an ancient city in Locris in central Greece. The Greek "Opoûs" and its adjective "Opoúntios" are ancient names for that place, which is why the plant is named after it. The connection to the city is the surprising part: a cactus from the Americas took its name from a Greek town that never had any link to it. The plant was unknown to classical Greeks and Romans, so the name was chosen for a European reader by a botanist who needed a Latin label. The "-ia" ending is the standard form for botanical genus names in Latin, and English took the Latin word directly as "opuntia", with the plural "opuntias" following normal English practice.
