In this presentation, David Costa will provide an introduction to MiamiIllinois, an Algonquian language of Indiana and Illinois. Costa will first discuss the geographic setting of Miami-Illinois and its place with Algonquian, following with an overview of the data sources on the language. He will also provide a brief sketch of the phonology of the Miami-Illinois, and, time permitting, finish with a discussion of some of the more notable grammatical features of the language, such as animacy, transitivity, pro-drop, obviation, and basic word order
