“Iroquoian languages, family of about 16 North American Indian languages aboriginally spoken around the eastern Great Lakes and in parts of the Middle Atlantic states and the South. Mohawk, Oneida, Onondaga, Cayuga, and Seneca, all originally spoken in New York, along with Tuscarora (originally spoken in North Carolina) and Cherokee (originally spoken in the southern Appalachians), are still spoken. No native speakers are known for the other Iroquoian languages, some long extinct.”

Though these languages are most properly known as ‘Algic’ to linguists (Wiyot and Yurok are not considered closely related enough to qualify as Algonquian, and the broader category Algic includes them as well), ‘Algonquian’ (also spelled ‘Algonkian’) is the general term most often used by the Native American people who speak them.

What does an Algonquian language sound like?  Well, it depends on which language you are talking about.  Some are very different from others.  Listen to them at http://www.atlas-ling.ca
