The potential position of intonational pauses is important for the analysis of word and phrase units. These potential positions of pause are also very significant in syntactic analysis. The fact that such intonational pauses do not occur within words provides the covert evidence of the morphological and phonological unity of a word.

An intonational pause may occur at the point of some external junctures and not of others. For example, in English the juncture which we write with a hyphen never coincides with an intonational pause, but the juncture which we may write with a space may coincide with such a pause.
