Forms
cactus m (genitive cactī); second declension[1] Pliny the Elder also has the Greek form cactos.[2]
Etymology
It is borrowed from Ancient Greek κάκτος (káktos, “cardoon”).[1][3][4] Beekes calls the Greek word a foreign word of unknown origin, and notes that Furnée took its ⟨κτ⟩ to point to Pre-Greek.[4]
Earliest recorded meaning
Pliny the Elder (c. 23–79 AD) describes the cactus as a plant that grows only in Sicily, whose stalks are eaten, even when preserved.[2][5][3]
Semantic evolution
Tertullian used it figuratively for anything thorny, speaking of rooting out omni cacto et rubo “every thorn and bramble” of a treacherous familiarity.[5]
English first took the word in the classical sense of the cardoon about 1600 and has applied it to the leafless spiny American plants since 1769.[6]
