A Computer Corpus-Based Study of Subject Raising in Modern Portuguese

This study is the first comprehensive, data-based examination of subject raising in Portuguese, and is based on 4500+ tokens in more than 26,500,000 words of text from both the written and spoken registers of Brazilian and European Portuguese. We have suggested that there are important differences in raising between the spoken and written registers, which are related to presumably universal production strategies for the two registers. Evidence suggests that morphological factors such as subject-verb agreement play an important role in determining whether raising occurs with first, second, and third person subjects. In terms of differences between the European and Brazilian dialects, we find that split agreement (eles parece saberem) and obligatory coreference {me parece ver um fantasma) are both more common in European Portuguese. Finally, these last two facts, along with a number of related phenomena, suggest that there are important differences in the underlying clause structure of European and Brazilian Portuguese, which can further be extended to include other languages such as Spanish.
