Mississippi แปลว่า

Although its current spelling may be derived from that of its much larger American cousin, it is most certainly a corruption of a different indigenous name, as the translation “great water” would not apply to a relatively minor tributary of the Ottawa, definitely the largest river in the area. Instead, the name may originate from Mazinaa[bikinigan]-ziibi, Algonquian for “[painted] image river”, referring to the pictographs found on Mazinaw Lake, though this is by no means proven.
