No, but I am a bit interested in Choctaw (a Muskogean language). At least on a superficial level, it has a couple surprising similarities to Hindi (like the word for yes is nasalized A, in Hindi nasalized hA - the word for good is achukmA, in Hindi achchhA). It's written in Latin letters, though, and I find it hard to figure out how some words are best pronounced. I kind of enjoy trying to write the words in Hindi script. Please let me know if you have any advice regarding study of Native American language at a basic level.
