Talk:Pawnee language

Pawnee sign language/hand signals?
I've started watching Yancy Derringer on Amazon Prime and one of the 3 main characters is Yancy's sidekick, a Pawnee who never speaks a word, but uses some sort of sign language to communicate with Yancy. Is that pure fiction, or do the Pawnee have a sign language as well? If they do, shouldn't that be mentioned in this Wiki article? Phantom in ca (talk) 08:12, 27 January 2017 (UTC)
