Definitions for "Concrete poetry"
poetry in which the poet's intent is conveyed by the shape formed by the letters, words, or symbols that make up the poem rather than by the conventional arrangement of words
poetry in which the physical arrangements of words are used to help suggest the author's meaning or theme, as in some poetry of Dylan Thomas and e.e. cummings.
poetry that is shaped to look like an object. John Hollander's "A State of Nature," for example, is arranged to look like New York State. Also called shaped verse.
