The plural of igloo is igloos.
An igloo is a traditional dome-shaped shelter made of blocks of snow or ice, typically used by indigenous communities in Arctic regions. Igloos provide insulation and protection against harsh weather conditions, maintaining a relatively stable and warm interior temperature. They are constructed by stacking and compacting snow blocks, taking advantage of the insulating properties of snow. Igloos are versatile structures that can be built quickly and serve as temporary dwellings for hunting or camping trips. They showcase the ingenuity and resourcefulness of cultures adapted to extreme cold environments.
