Hiráaca, also known as Hidatsa (Hiráaca nooga ire’e), is a Siouan language spoken by the Hiráaca people of the Northern Plains and is one of the three languages of the Mandan, Hidatsa, and Arikara (MHA) Nation. While the three tribes function together as a single political entity, each maintains its own distinct language and cultural traditions. Today, the Hiráaca people are centered along the Knife and Missouri Rivers in present-day North Dakota, where their ancestors established villages centuries ago. Community estimates suggest that only about 30 first-language fluent speakers remain, making language revitalization an urgent priority.
Organized by Lisa Casarez with the support of Hiráaca language workers and community members, this course was created as a resource for both classrooms and independent learners. Designed to build a strong foundation in the language, it reflects the dedication of the elders, teachers, and families working to ensure that future generations can continue to find connection, pride, and identity through Hiráaca.
