Abstract
In an attempt to extend the minimalist program, Collins (2002) tries to eliminate syntactic labels from syntactic theory. However, labels have been used in many theories of the syntax-phonology interface. It is argued that these label-based theories have not only the conceptual problem of using labels but also empirical problems in three areas: (i) non-branching XPs, (ii) variable phrasing, and (iii) a variety of prosodic categories. These empirical problems also arise with Collins's label-free approach which uses multiple Spell-Out. An alternative theory of the PF interface is proposed which maps label-free phrase structure onto prosodic structure with boundaries.
