The objective of this doctoral thesis is to approach the culture of the Muinane people through their history and language. We describe some ethnographic and historical aspects of the indigenous muinane group living in the colombian Amazon. We are concerned with the study of their language and particularly with the lexical categorization and with the comparison between the muinane, bora and miraña, all classified as integrating the bora linguistic family. In other words, our goal is to define the classes of lexical categories of the muinane from a typological perspective, and to determine the phonological, morphosyntactical and discursive criteria, which allow us to define this categorization. We debate here the question of the existence or the absence of an adjectival category in the bora languages and the strategies used by their speakers to express qualification and attribution. Finally, we propose a relationship between some languages spoken in the northwest Amazon, which don’t exhibit an adjectival class but have a rich and salient system of nominal classification such as the languages from the bora, uitoto and eastern tukanoan linguistic families.
