The selection of words in a literary work. A work's diction forms one of its centrally important literary elements, as writers use words to convey action, reveal character, imply attitudes, identify themes, and suggest values. We can speak of the diction particular to a character, as in Iago's and Desdemona's very different ways of speaking in Othello. We can also refer to a poet's diction as represented over the body of his or her work, as in Donne's or Hughes's diction.
