What does Missouri mean?

Missouri gets its name from a tribe of Sioux Indians of the state called the Missouris. The word "Missouri" often has been construed to mean "muddy water" but the Smithsonian Institution Bureau of American Ethnology has stated it means "town of the large canoes," and authorities have said the Indian syllables from which the word comes mean "wooden canoe people" or "he of the big canoe."
