A parka or anorak is a type of coat with a hood, often lined with fur or faux fur. The Caribou Inuit invented this kind of garment, originally made from caribou or seal skin, for hunting and kayaking in the frigid Arctic. Some Inuit anoraks require regular coating with fish oil to retain their water resistance.
The words anorak and parka have been used interchangeably, but they are somewhat different garments. Strictly speaking, an anorak is a waterproof, hooded, pull-over jacket without a front opening, and sometimes drawstrings at the waist and cuffs, and a parka is a hip-length cold-weather coat, typically stuffed with down or very warm synthetic fiber, and with a fur-lined hood.
The word anorak comes from the Kalaallisut word annoraaq. It did not appear in English until 1924; an early definition is "a beaded item worn by Greenland women or brides in the 1930s". In the early 1950s it was made from nylon, but changed to poplin by 1959, when it was featured in Vogue magazine as a fashion item. In 1984, The Observer used the term to refer to the type of people who wore it and subsequently, in the United Kingdom, it is sometimes used as a mildly derogatory term.
The word parka is derived from the Nenets language. In the Aleutian Islands the word simply means "animal skin". It first entered the English written record in a 1625 work by Samuel Purchas.
