Abstract
This paper describes the research of Dr. Gilberto Sánchez Cabezas and his importance in the lexical aspect of Spanish-Mapudungun contact in Chilean territory. This Mapuche language scholar is relevant today due to his reconsideration of Rodolfo Lenz’s ideas and the life experiences linked to the quality and authenticity of his academic work, which contribute to a genuine recognition of the connection between culture and language within the discipline of ethnolinguistics. The author is not only important in the field of linguistics, but his approaches are also linked to interculturality for the territory and one of the most relevant ways of transforming our society: education.
