Fig 6 gives a typical example of this phenomenon, where the noun possession is followed by a prepositional complement, while Fig 7 represents  The special prosodic status of lexical heads is incorporated in Selkirk's (1981) notion of ϕ-phrase, and subsequent developments thereof, such as (Selkirk, 1986;Nespor and Vogel, 1986  Turning back briefly to the Head-Specifier Rule shown in Fig 5, we can now see that if ϕ 0 is a metrical tree M, then the value of extMtr(ϕ 1 ϕ 0 ) depends on the syntactic information associated with the leftmost element P of that tree.
if P is the phonology of the lexical head of the phrase, then it can be prosodically disjoined from the following material, otherwise the metrical tree M is extended in the standard way.
