From its verb "cupere" ("to desire") Latin derived three nouns which have passed with minimal modification into English. "Cupiditas" meant "yearning" and "desire"; English borrowed this as "cupidity," which originally in the 15th century was synonymous with "lust." (The "greed" meaning of "cupidity" developed very soon after this other now-archaic meaning.) Latin "cupido" started out as a near synonym of "cupiditas," but it came to stand for the personification of specifically carnal desire, the counterpart of Greek "eros"; this is the source of our familiar (and rather domesticated) Cupid. A strengthened form of "cupere" -- "concupiscere," meaning "to desire ardently" -- yielded the noun "concupiscentia" in the Late Latin of the Christian church. "Concupiscentia" came specially to denote sexual desire, a meaning reflected in the English version "concupiscence," meaning "sexual desire."
