The article discusses the impact of COVID-19 on the preservation of indigenous languages in Brazil, focusing on the Puruborá people and their language. Eliézer Puruborá, one of the last native speakers, passed away from COVID-19, further endangering the language spoken by a small community of 220. The pandemic has exacerbated the situation by causing the death of elders, who are key to language preservation, and by disrupting cultural events and language stewardship activities. The Puruborá have been working with linguist Ana Vilacy Galucio from the Emílio Goeldi Paraense Museum to create an audio archive of their language. However, the remaining semi-fluent elders are at risk due to the pandemic. The article also mentions the Guarani Mbya, who have found an unexpected boost in language interest through online classes during the pandemic. The Puruborá are determined to continue their efforts to preserve their language and culture post-pandemic.
