Island
An island or isle is any piece of sub-continental land that is surrounded by water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. A grouping of geographically or geologically related islands is called an archipelago, such as the Philippines.

Rockall is a small rocky islet in the North Atlantic which was declared part of Scotland by the Island of Rockall Act 1972. However, despite no possession by any other state and other precedents, the legality of the claim is disputed by the Republic of Ireland, Denmark and Iceland and some say, it may be unenforceable in international law.
