Delaware is an Algonquian language spoken mostly in Oklahoma, though historically it was spoken in the northeastern part of the USA, especially in New Jersey and Delaware. The language is almost extinct; only a few elders speak it, all of whom are over 90 years old. As with many Native American languages, many younger Lenape are trying to learn the language of their ancestors, but it is difficult.
The native name for the Delaware language and people, Lenape, means 'original people'. The Unami or Wënami were a group of Delawares who lived south of the Raritan River and the Delaware Water Gap. The Delaware word for house, wikwam, is probably the origin of the English word wigwam.
