Grammatical borrowing from Spanish/Portuguese in some native languages of Latin America

In this paper I investigate how different factors can influence the range of grammatical categories affected by language contact, drawing on a sample of ten native languages of Latin America. The languages are all in contact with the highly dominant languages Spanish and Portuguese, but they differ with respect to a range of sociolinguistic factors relating to the contact situation. I am investigating the categories affected by borrowing in the languages of the sample, relating them to these different factors. My aim is to shed light on the reasons for why some Native American languages display borrowing in a wide range of categories, whereas other appears more restricted in what is borrowed
