How do you prononce Quiatenon?

Answer 1

Quiatenon (or Ouiatenon) seems to be a major village of the Wea tribe, who were themselves part of the Miami people. In an early French account the word is written Oui-a-tanon.

This is said to mean "Wea Town", so it seems very likely that the initial O has been mistaken for a Q at some time, changing the word from OUIA-tanon (pronounced Weatanon) to QUIAtenon. This misunderstanding is typical of European difficulties with native languages.
