Arapaho, which is also spelled Arapahoe or Arrapahoe, is an Algonquian language with between 250 and 1,000 speakers in Wyoming, most of whom are elderly. The Arapaho are currently working to revitalize their language among the younger members of their nation.
There are two main groups of Arapaho: the Nortern Arapaho, who live in Wyoming, and the Southern Arapaho, who live in Oklahoma with the Cheyenne. The Arapaho call themselves Hinono'eiteen ('our people').
Arapaho is closely related to Gros Ventre (Ahe/A'ananin) to the extent that the two languages are largely mutually comprehsible.
Arapaho is a tonal language and tones are marked as follows:

First I'll tell a story.
I went down there to Oklahoma with my brother in law Alonzo Moss.
I went down there to be with them.
When the Oklahoma people tell how they've lost our language, they are pitiful.
There aren't many who still speak it.
