This thesis embarks on an exploration of language ideology, centering its investigation on the debate surrounding the nomenclature of the Spanish language as "castellano" or "español." It explores the concept of language ideologies by exploring the ideological underpinnings of the debate over naming the Spanish language, probing historical, cultural, and political factors that shape the ideologies associated with "castellano" and "español." The investigation extends beyond the traditional debate by engaging textual artifacts in an imagined conversation. It situates the debate in its historical context to expose the complex network of interconnected ideologies, encompassing both linguistic and non-linguistic realms.
