Diction (; (nom. ), "a saying, expression, word"), in its original, primary meaning, refers to the writer's or the speaker's distinctive vocabulary choices and style of expression in a poem or story. A secondary, common meaning of "diction" means the distinctiveness of speech, the art of speaking so that each word is clearly heard and understood to its fullest complexity and extremity, and concerns pronunciation and tone, rather than word choice and style. This secondary sense is more precisely and commonly expressed with the term enunciation, or with its synonym articulation.
