Intonational phrase

An intonational phrase is a phonological unit with the following properties: (i) it is the largest phonological unit into which an utterance can be divided, (ii) it has a specifiable intonational structure including a single most prominent point (the nucleus), and it matches up in some way with syntactic and discourse structure.

Comments
It seems that the term (or its variant intonation phrase) became popular through the influence of Pierrehumbrt (1980).
