This dissertation examines the phenomenon of Mock Kichwa in memes shared on social media in Ecuador, focusing on how these memes contribute to racism and reflect enduring colonial raciolinguistic ideologies. Ecuador is a multilingual society where Spanish is the dominant language, and Kichwa is the most widely spoken Indigenous language in the Highlands. Due to centuries of contact between Spanish and Kichwa, there exists a continuum of Ecuadorian Andean Spanish (EAS) varieties, some of which are stigmatized and mocked, particularly by the white-mestizo population. This study investigates the linguistic and semiotic strategies used in these memes, exploring how both Indigenous and non-Indigenous people perceive them, while highlighting Ecuador's distinct sociopolitical dynamics and racial constructs, such as mestizaje and indigeneity, which shape these perceptions. Building on the concept of Mock Spanish (Hill, 1995) and raciolinguistic ideologies (Rosa and Flores, 2017), which link seemingly "innocent" or humorous practices to underlying beliefs about language, race, and class, this research extends these frameworks to the context of Latin America. By analyzing a corpus of 50 memes collected between 2020 and 2024, and incorporating ethnographic data from questionnaires and focus groups, this dissertation reveals that Mock Kichwa relies heavily on stigmatized linguistic features of EAS. These features include vowel neutralization, the representation of /ʃ/ as "sh" instead of "ll," the assibilation of the rhotic sounds /r/ and /ɾ/, the use of Kichwa words with negative connotations in EAS, and the hyper-use of EAS morphosyntactic features. The study employs diverse community-based and decolonial methodologies, such as multimodal semiotic analysis, Critical Discourse Analysis, and focus groups, to understand how language and race are co-constructed in these digital spaces and subsequently experienced in other contexts. Memes are analyzed as "semiotic packages" that combine linguistic and non-linguistic elements, serving as key indexes of social meaning. By utilizing the concept of "indexicality," this dissertation moves beyond a focus solely on mock languages, instead reflecting the diverse indexing practices that characterize the construction of Mock Kichwa and, more importantly, the underlying language ideologies that perpetuate social inequity. The findings highlight how Mock Kichwa in social media memes perpetuates social hierarchies and racist ideologies, continuing the marginalization of Indigenous communities. These memes are not merely playful or humorous; they serve as tools of power and control that reinforce existing social structures. This dissertation also underscores the ongoing resistance and contestation by Indigenous peoples, who continuously challenge racism and colonial legacies, leading to unique forms of resistance and language revitalization.
