A sociohistorical and sociolinguistic analysis of languages and peoples in the Andean region reveals that the greatest challenges for their study and revitalization come from prevailing ideologies in the region since the colonial period. This presentation argues that several elements of Quijano’s ‘colonial racism’ (cf. 2021), and expressed in various concepts in colonial documents (cf. “La Humanidad es una” by Hanke 1974), persist beyond the colonial era in discussions about American Spanish (cf. del Valle 2007), including the reference about the ‘indigenous factor’ highlighted by Menéndez Pidal (1918). More recently, we find such expressions in covert reinterpretations about sociolinguistic diversity in Latin America (cf. Alberto Escobar 1972), in the Andes (Howard 2007), and in discussions about ‘different types of education’ (cf. Vich & Zavala 2019) in the region. This presentation focuses on how these covert reinterpretations of ‘colonial racism’ negatively impact the study of languages and their populations in the Andean region, giving rise to persistent myths, both within and outside academia, about ‘Andean Spanish,’ its linguistic features, its speakers, and the study of Spanish in contact with Amerindian languages. An analysis contrasting (socio)linguistic analysis and social evaluations (Escobar, unpublished) is presented to unveil some of these myths.
