"Traditional poetry" applies to the classical forms in rhyme, meter, and language. The later Modernist or Postmodernist forms have the spirit and content of poetry, but lack the traditional organization. Critics of free verse and other forms often allude to traditional forms as "proper poetry".
Poetry (from the Greek "ποίησις", poiesis, a "making") is a form of literary art in which language is used for its aesthetic and evocative qualities in addition to, or in lieu of, its apparent meaning. Poetry may be written independently, as discrete poems, or may occur in conjunction with other arts, as in poetic drama, hymns or lyrics.
