The poet and critic Rachel Blau DuPlessis defines anacoluthon as "the grammatical switching of horses in midstream of a sentence: beginning a sentence in one grammar and ending it in another." She argues that it involves "the employing of multiple discursive ranges and disjunctive transpositions from one to the other[,] hence in any one poem, far from being in one mode, one register, one stable voice, a writer is like an acrobat ... a Barthesean weaver of a wacky fabric, or someone who 'samples', like a certain kind of contemporary DJ."
