Omaha is a Siouan language spoken in Nebraska in the USA by 60 people, 25 of whom are fluent, and of of whom are over 60 years old. Omaha is mutually intelligible with Ponca, which has a handful of speakers in Oklahoma and Nebraska. The Omaha and Ponca people consider their languages to be separate, however some consider them variants of one language: Omaha-Ponca, which is part of the Dhegiha dialect continuum along with Kansa, Osage and Quapaw.
The Omaha language was first documented in 1890 and 1891 by James O. Dorsey for the Bureau of American Ethnology. He devised a way of writing the language, known as the Dorsey Orthography, and other researchers came up with other ways of writing the language.
The orthography shown one below is used in the Omaha Nation Public School in Macy in Nebraska, and in Omaha Language Classes at the University of Nebraska-Lincoln.
An accute accent (á) is used to indicate syllable stress, and stress placement can change the meaning of words. For example: wáthatʰe = table; wathátʰe = food
\op Di´xe e´goñ-biama´. He´gazhi t'a´-biama´. Ga´xthoñ
athai´ te ha te´ une´.
\op Poñ´ka ama´di ahi´-biama´. Te´ wa´thatai te Poñ´ka ama´. Ki the´-ma she´toñ
