A wigwam is like a house that Native American people made a long time ago. It's made out of sticks, branches, and sometimes animal skins. They used these materials to build a dome-shaped structure that could shelter them from the wind, rain and other weather. The wigwam was typically used by one family and had a small entrance where you could go in and out. Inside, it had a fire in the middle that kept the family warm and could be used for cooking food. So basically, a wigwam is a special kind of home that Native American people built, so they had a safe place to live.
