What is the native American word for mom?

The Word "Indian" is a very vague term that could easily refer to the many languages of India; if you are asking for an example of a native American Word for "mother" out of many hundreds (even thousands) of possible Words, then the Natick Word is okasu or witchwhaw.

Natick is the name of the Algonquian language spoken by the Wampanoag, Narragansett and Massachusetts tribes.
