What country does the word teepee come from?

The word "teepee" comes from the Lakota language, a Native American language spoken by the Lakota people, who are part of the Sioux Nation.

It's important to note that the word "teepee" is a somewhat simplified and often inaccurate translation. The Lakota word for the dwelling is "tipi", which translates more accurately to "dwelling" or "house."
