ABSTRACT
As mentioned in Chapter 3, in the literature on the syntax-phonology interface a distinction has been made between lexical and functional projections and heads. For example, Chomsky and Halle (1968) argue that only lexical projections and their heads need to be marked with a phrasal domain marker, #, meaning that only lexical projections are represented in the phonology (see §1.1 for further discussion of this proposal). According to Chomsky and Halle, lexical projections include adjective phrases, noun phrases and verb phrases. The subsequent literature on the syntax-phonology interface directly follows this original breakdown between functional and lexical. For example, Nespor and Vogel (1986) argue that phonological domains are constructed by grouping a Clitic Group (p. 168)
which contains a lexical head (X) and all Clitic Groups on its non-recursive side up to the Clitic Group that contains another head outside of the maximal projection of X.
