Semantics of Under-Represented Languages in the Americas 11 has been hosted by El Colegio de México and Universidad Nacional Autónoma de México, August 4 - 7, 2020. The goal of the conference is to bring together researchers working on indigenous languages and dialects spoken in the Americas in order to strengthen the connection between semantic fieldwork and formal semantic theory. We encourage the participation of linguists involved in fieldwork, language documentation and revitalization who also carry out theoretically oriented analyses. Graduate students are strongly encouraged to participate.
