iglu

Iglu is an Inuktitut word meaning 'house' or 'dwelling.' Inuktitut, spoken across the Canadian Arctic, Greenland, and Alaska, has no special word for a snow house—it uses the same word for any structure where people live. English borrowed iglu and applied it exclusively to snow houses built for hunting in winter. The English narrowed the meaning; the original word is broader.

In traditional Inuit life, iglus were temporary hunting shelters, built quickly during winter hunts to provide emergency shelter. They were never year-round homes (that misconception comes from English mistranslation). Seal-hunting camps, walrus-hunting camps, trading expeditions—these required temporary shelters. The snow house was ingenious: blocks of packed snow provide insulation. No wood required. No tools beyond a snow knife. Built in hours.

The construction was practical architecture, not primitive desperation. The spiral dome structure distributes stress efficiently. The entrance tunnel prevents wind from entering. Snow blocks are carved with an entrance angled upward, so warmer air stays inside. Heat from the bodies and a single oil lamp raises the interior temperature above freezing, but not so much that the walls melt. The engineering is sophisticated.

Igloos are vanishing. Modern heated houses, snowmobiles, and climate change have made traditional snow house construction rare. The Inuit still use the word iglu for modern houses. English used the word for only snow houses, then slowly stopped using it at all as igloos became archaeological artifacts. But in Inuktitut, iglu means home—unchanging, universal, still spoken in the Arctic today.
