The original Inuktitut word, "anorak", refers to a traditional hooded garment worn by the Inuit people for warmth and protection from the elements. This garment was typically made from animal skins and was essential for survival in the harsh Arctic climate.
The word "anorak" eventually spread to other languages, including English, where it came to be used to describe a type of windproof jacket, particularly one associated with outdoor pursuits.
