The Mobilian Trade Jargon was a pidgin trade language based on Choctaw and
Chickasaw and used throughout the American southeast. Like all pidgins,
the Mobilian Jargon has extremely simplified grammar compared to the complex sentence structure of Choctaw and other Muskogean languages.
Choctaw and Chickasaw are still vigorous languages today, but the Mobilian pidgin hasn't been spoken since the 1970's.
