Geologically, a fjord (/ˈfjɔərd/ or Listeni/ˈfiːɔərd/; also spelled fiord) is a long, narrow inlet with steep sides or cliffs, created by glacial erosion. The word comes to English from Icelandic, but related words are used in several Scandinavian languages, in many cases to refer to any long narrow body of water other than the more specific meaning it has in English. The coasts of Norway, Iceland, and Greenland have many fjords.
