The support copula in the left periphery

This chapter presents novel evidence for the morphological support approach to the copula, based on data from non-standard amalgam specificational copular constructions in English, like We need coffee is what we need. In these constructions, the copula linking the two clauses shows unusual syntactic and semantic properties. Evidence from an interpretation experiment shows that, although it is inflected for tense, the copula of an amalgam construction fails to associate with semantic tense. Furthermore, the amalgam copula cannot associate with the syntactic hallmarks of the T-domain or the V-domain; however, it can combine with material from the C-domain, suggesting that in these constructions, only the C-domain is present. To account for the amalgam specificational copular construction, a late-insertion analysis of the copula is adopted, under which the inflected forms of the copula are inserted as morphological support wherever inflectional features, combinations of [fin], [tense], and [φ‎], are stranded on a functional head. Since these features can be spelled out on a copula in C in the absence of T and V, it must be the case that higher functional projections can be independent from lower ones.
