Etymology of poet

poet

c.1300, from O.Fr. poete (12c.), from L. poeta "poet, author," from Gk. poetes "maker, author, poet," from poiein "to make or compose," from PIE *kwoiwo-"making," from base *kwei- "to make" (cf. Skt. cinoti "heaping up, piling up," O.C.S. cinu "act, deed, order"). Replaced O.E. scop (which survives in scoff). Used in 14c., as in classical languages, for all sorts of writers or composers of works of literature. Poète maudit, “a poet insufficiently appreciated by his contemporaries,” lit. “cursed poet,” attested by 1930, from French (1884, Verlaine).

poem

1540s (replacing poesy), from M.Fr. poème (14c.), from L. poema "verse, poetry," from Gk. poema "thing made or created, fiction, poetical work," from poein"to make or compose"

poetry

late 14c., from O.Fr. poetrie (13c.), from M.L. poetria (c.650), from L. poeta (see poet). In classical Latin, poetria meant "poetess." English lacks a true verb form in this group of words, though poeticize (1804), poetize (1580s, from Fr. poétiser), and poetrize (c.1600) all have been tried.
