Pre-verbal position in BP: a reinterpretation of the "avoid pronoun principle"

Аннотация

The aim of this paper is to analyze the changes occurring in Brazilian Portuguese, regarding the possibility of null subjects, and suggest the kinds of constraints that explain its present distribution. In this paper, we will propose that the null subject parameter is defi ned at the interfaces. At the level of Logical Form, a constraint like Chomsky’s (1981) Avoid Pronoun will be at
work for languages that are prototypical null subject languages, like Spanish and Chinese. For languages like BP, a system with a particular distribution of null subjects, the constraint will be more specifi c: Avoid non-referential pronouns. We will also propose that at the other interface, the Phonetic Form, languages have fi lters regarding their rhythm. To account for the preference for certain forms, a constraint of the form: Avoid V1 will be proposed. This constraint has
nothing to do with an XP constituent in Spec of C, like in V2 languages, but with a phonetic requirement. This means that the initial element can be a head or an XP.
