What's the Difference Between a Wigwam and a Teepee?

A wigwam is a tent and a teepee is another type of tent. They're actually very similar, some people might even use the words interchangeably. The difference is a wigwam was intended to be more permanent. But there are other types of ethnic tents aren't there? Well, yes, there's a yurt. Which, I don't know exactly where it's from, but I know it's like a very, very big wigwam or teepees.
