Where does “Epicureanism” come from?

Epicureanism derives from English Epicurean combined with Ancient Greek -ισμός (suffix forming abstract nouns), itself from Ancient Greek -μός, from Proto-Indo-European -mós, ultimately based on Ancient Greek ἐπίκουρος (Epicurus, a name) and Ancient Greek ἐπι- (prefix meaning "upon" or "toward").
