Hidatsa (/hɪˈdɑːtsə/ hih-DAHT-sə)[page needed] is an endangered Siouan language that is related to the Crow language. It is spoken by the Hidatsa tribe, primarily in North Dakota and South Dakota. A description of Hidatsa-Mandan culture, including a grammar and vocabulary of the language, was published in 1877 by Washington Matthews, a government physician who lived among the Hidatsa at the Fort Berthold Indian Reservation. More recently, the language has been the subject of work in the generative grammar tradition. In 2019, it was estimated that there were fewer than 65 fluent speakers of the language. Sacagawea Linguists working on Hidatsa since the 1870s have considered the name of Sacagawea, a guide and interpreter on the Lewis and Clark Expedition, to be of Hidatsa orig
