More than 200 scholars from Minnesota, neighboring states and Canada gathered this week at the first-ever Minnesota Indigenous Language Symposium. The symposium is hosted by the University of Minnesota Department of American Indian Studies and the Grotto Foundation. The participants are discussing how to revitalize the indigenous languages spoken in this region, which include Ojibwe and Dakota. Tony Treuer is an assistant professor of Ojibwe at Bemidji State University. He told MPR's All Things Considered host David Molpus the languages have long been threatened, and continue to face extinction.
