Iglu, also known as igloo, is a term that refers to a dome-shaped dwelling made of snow blocks. It has been widely used by indigenous people in the polar regions, such as Eskimos. Over time, people have come up with several synonyms to describe iglu based on their language, culture, or purpose. Some of the most common ones are tupiq, khan, chum, yaranga, and quinzhee. Tupiq is a term used by Inuit people in Canada, while khan is the Mongolian word for a portable yurt-like dwelling. Chum is a traditional tent-like structure used by Siberian nomads, and yaranga is a wooden-framed house covered with animal skins or canvas by the indigenous people in the Russian Arctic. Quinzhee, on the other hand, is a snow shelter similar to iglu but made by hollowing out a pile of snow.
