Resumen de Overt subjects in early Basque and other null subject languages
Maria José Ezeizabarrena Segurola
This study focuses on person marking in early Basque and other null subject languages. From very early on, person marking on the verb and quite regular, adult-like, null subject rates are attested across early acquisition studies on genetically related and unrelated pro-drop languages. We survey several studies on bilingual children simultaneously acquiring two languages with the opposite value for the pro-drop parameter. The conclusion drawn is that children display a monolingual-like pattern in the production of person marking, overt subjects, and personal pronouns in the null subject language, whereas, in the non-null subject language, bilinguals evidence delayed target person marking and overt subject production. These data are compatible with the view that children correctly set the default parametric value at early stages and separate the languages being acquired. However, it is argued that accounts based on the lexical learning of features in the functional category T(ense) may better account for the crosslinguistic data. Moreover, the accuracy observed in overt person inflection production leads to the proposal that (the spelling out of) the [person] or [D] feature in T(ense) is the first subject feature available to the language acquirer, previous to other candidates such as number or case.
