early 14c., "a poet, a singer" (c. 1200 as a surname), from Old French poete (12c., Modern French poète) and directly from Latin poeta "a poet," from Greek poetes "maker, author, poet," variant of poietes, from poein, poiein "to make, create, compose," from PIE *kwoiwo- "making," from root *kwei- "to pile up, build, make" (source also of Sanskrit cinoti "heaping up, piling up," Old Church Slavonic činu "act, deed, order").
Replaced Old English 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," literally "cursed poet," attested by 1930, from French (1884, Verlaine). For poet laureate see laureate.
“Communication” will not explain poetry. I will not say that there is not always some varying degree of communication in poetry, or that poetry could exist without any communication taking place. There is room for very great individual variation n the motives of equally good individual poets; and we have the assurance of Coleridge, with the approval of Mr. Housman, that “poetry gives most pleasure when only generally and not perfectly understood.” [T.S. Eliot, “The Use of Poetry and the Use of Criticism”]
