What is the Sioux word for little she bear?

The Lakota word mahto (in some modern orthographies written matho) is generic for any kind of bear, male or female. The word for little is chinchala, so mahto chinchala is "little bear" of either sex.

In order to emphatically specify a female bear you would need to add winyela, which can be used of humans or animals; if you are thinking about a female human being with the name "Little Bear" you would have to add -win to the end of the name.

So:

  • mahto chinchala = a little bear
  • mahto chinchala winyela = a little bear that is female
  • mahto chinchalawin = a woman called Little Bear
