The five chapters of this study describe and deepen our knowledge of word class changing and formation and the construction of complex sentences through different complementation processes. Through these mechanisms, the nature of mapudungun to renew its lexicon and to create new registers and discourses can be seen. In synthesis, this study is a contribution to our knowledge of mapudungun; it allows us to understand how words are formed and how they are used to form complex sentences. There are also discoveries that are relevant to understanding mapudungun grammar, as well as some unpublished observations regarding the form and significance of little studied constructions in mapudungun Show less
