Chahi
In major metropolitan areas, the trade tongue known as Chahi ("The Mix") is widely spoken. In Cahokia, nearly all adults are fluent, and children are taught from a young age. Chahi is a blend of Ojibwe and Lakota, with influences from various languages encountered by Cahokian traders.
Chahi emerged when Anishinaabe and other Algonquin-speaking refugees fled south due to climate shifts, settling around the Great Lakes. These refugees used their trading networks and gradually integrated Lakota, Dakota, and Nakoda influences. Over time, Chahi evolved into an independent language with Siouan vocabulary and Algonquin grammar.
