• This paper explores the syntax of main clause predicatives from the perspective of trying to account for an asymmetry in copular constructions in certain languages. One of the languages in which we find such an asymmetry is child English (around age 2). Specifically, new results show that children acquiring English tend to use an overt (and inflected) copula in individual-level predicatives, but they tend to omit the copula in stage-level predicatives. The analysis adopted to account for this pattern draws on evidence from adult English, Russian, Spanish and Portuguese that stage-level predicates are Aspectual (they contain AspP) while individual-level predicates are not (they involve only a lexical Small Clause predicate). Children's omission of the copula in structures with AspP is linked to the fact that at this stage of development, children fail to require finiteness in main clauses. In particular, Asp0 is temporally anchored in child English, thereby obviating the need for a finite (temporally anchored) Infl, i.e. an inflected copula.
