The copula has been one of the most important sites for work on the origins of African American Vernacular English (AAVE). In particular, the effects of the following grammatical environment on copula absence have been crucial in attempts by linguists to argue a creole origins hypothesis. 1 Almost thirty years of copula research have confirmed the ordering of gonna, V+ing, predicate locative/predicate adjective, and NP in the constraint hierarchy for the effects of the following grammatical environment on copula absence. The ordering of predicate locatives and adjectives has been a source of controversy, though, with different analyses finding different orderings for these environments. However, it is the ordering of predicate locative/predicate adjective with respect to one another that has been singled out by researchers as a key factor in determining a creole ancestry for AAVE. Scholars such as Baugh (1979( , 1980( ), Holm (1984, Rickford and Blake (1990), and Rickford (1998) have argued that an AAVE constraint ordering that shows higher copula absence rates for following predicate adjectives than for predicate locatives parallels similar constraints in Caribbean anglophone creoles, which would strongly suggest creole origins for AAVE. These researchers point to the fact that in African languages and in creoles such as Jamaican Creole and Gullah, adjectives are a subclass of verbs and consequently would not require a preceding copula (Holm 1984, 102).Research on diaspora varieties of AAVE, however, has called the creole constraint order (and the creole hypothesis) into question. Poplack and Sankoff (1987) show that the ordering of the following grammatical constraints on copula absence
