Mobilian Jargon

Mobilian Jargon (also Mobilian trade language, Mobilian Trade Jargon, Chickasaw–Choctaw trade language, Yamá) was a pidgin used as a lingua franca among Native American groups living along the Gulf of Mexico around the time of European settlement of the region. The name refers to the Mobile Indians of the central Gulf Coast.

Mobilian Jargon facilitated trade between tribes speaking different languages and European settlers. There is continuing debate as to when Mobilian Jargon first began to be spoken. Some scholars, such as James Crawford, have argued that Mobilian Jargon has its origins in the linguistically diverse environment following the establishment of the French colony of Louisiana. Others, however, suggest that the already linguistically diverse environment of the lower Mississippi basin drove the need for a common method of communication prior to regular contact with Europeans.
