Linguistics courses contain a lot of language data, but the data is sometimes disconnected from the people, communities, and cultures that use the language. In contrast, in this course, students actively engage with language in context. The course focuses on language documentation, introducing students to the source of linguistic datasets and to the ethics of language documentation. We will examine historical changes in how languages are documented, along with the contributions that community involvement has made to the field of linguistics. We will analyze the importance of contextual factors like culture, history, and geography in shaping languages, by exploring specific case studies of language-context connection. Finally, we will look in depth at language marginalization and the causes of language loss and endangerment. In doing so, we will learn about what it means for a language to be endangered, factors that contribute to language shift, and revitalization efforts that aim to reverse it.
