Probably from Hidatsa
tsakáka wía meaning "bird woman". Alternatively it could originate from the Shoshone language and mean "boat puller". This name was borne by a Native American woman who guided the explorers Lewis and Clark. She was of Shoshone ancestry but had been abducted in her youth and raised by a Hidatsa tribe.
