Another great post Noel ~
I also am a fan of languages - do you know about "Chinook Jargon"? It's an Indian trade language that's now extinct, but we have several books in Western History about it and giving its grammar and lexicon. Seasoned travelers, scouts and trailblazers knew some of this pidgin dialect, if they were worth their salt....
Just search "Chinook Jargon" and see what we've got.
