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.
Administrative divisions of the Maldives
The administrative definition of an "island" differs from the actual meaning of the word 'island'. While naturally, an "island" refers to a land-mass surrounded by water, an "island" in the administrative sense, refers to a specified inhabited area within an administrative atoll, which is governed over by an "island council". While the majority of "island" class constituencies are indeed natural islands, there are 8 constituencies at "island" class, that are not naturally islands. (The 8 wards of Fuvahmulah Island are administratively considered "islands")
There are 189 such islands, each with its own island council. (Except for Felivaru, Lhaviyani Atoll)
