In linguistics, prosody (pronounced /ˈprɒsədi/ pross-ə-dee, from Greek προσῳδία, prosōidía, [prosɔːdía], “song sung to music; pronunciation of syllable”) is the rhythm, stress, and intonation of speech. Prosody may reflect various features of the speaker or the utterance: the emotional state of the speaker; the form of the utterance (statement, question, or command); the presence of irony or sarcasm; emphasis, contrast, and focus; or other elements of language that may not be encoded by grammar or choice of vocabulary.
