Children with Specific Language Impairment (SU) have well known difficulties with the obligatory use of verbal tense-marking morphology which they use optionally for a longer period of time than typically developing children. Copula BE and auxiliary BE are two tense markers that have been shown to be problematic for children with SU, but their status as independent allomorphs is somewhat controversial in the literature. In the present study we argue for copula BE and auxiliary BE as two separate tense markers showing different developmental curves both for children with SLI and for younger unaffected controls. It is suggested that copular versus auxiliary status, morphological form, and the frequency of the lexical construction containing be all affect children's provision of copular and auxiliary forms. Implications for identifying variables constraining optionality are discussed.
