The adjective is derived from Prometheus (“demigod in Greek mythology”) + -an (suffix meaning ‘of or pertaining to’ forming adjectives; and forming agent nouns). Prometheus is a learned borrowing from Latin Promētheus, and from its etymon Ancient Greek Προμηθεύς (Promētheús), from προμηθής (promēthḗs, “having forethought”) (from προ- (pro-, prefix meaning ‘before’) + μᾰνθᾰ́νω (mănthắnō, “to learn; to know, understand”) (ultimately from Proto-Indo-European *men- (“to mind; to think”) + *dʰeh₁- (“to do; to place, put”), in the sense of putting one’s mind to something)) + -εύς (-eús, suffix forming a masculine noun of the person concerned with a thing). The noun is derived from the adjective.
