What Latvian tells us about strong PCC effects

Resumen

The nature of Person Case Constraints (PCC) in natural languages is among the most debated issues in current linguistic research. In this article we consider an instance of strong PCC attested in the Latvian debitive construction, whereby a 1^st or 2^nd person internal argument cannot appear in the nominative in the presence of a dative debitor. We argue that the Latvian facts support an analysis of strong PCC effects along the lines of Sigurðsson’s (2002, 2004) proposal that PCC is due to a dative intervention effect inside a multiheaded approach to pronominal licensing. We preliminarily extend the analysis to other instances of strong PCC effects, showing that Sigurðsson’s theory is a good candidate to unify strong PCC effects under a common treatment.
