The neighbouring Campa languages have probably also been in contact with Quechua. In this thesis the influence of Quechua on Yanesha on the one hand and on Campa languages on the other hand are compared, with the focus on structural features of the languages. It becomes clear that Quechua influence on the grammar of Yanesha is meagre. In Campa languages the inclusive-exclusive distinction is probably due to Quechua influence, but this seems to be the only major change in Campa structure because of Quechua. This case study challenges most of the existing theories about structural changes that follow lexical influence (Campa) and those theories who claim that the situation that causes heavy lexical influx, would also cause influence on the structure (Yanesha).Show less
