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.
List of municipalities on Long Island
A village is an incorporated area which is usually, but not always, within a single town. A village is a clearly defined municipality that provides the services closest to the residents, such as garbage collection, street and highway maintenance, street lighting and building codes. Some villages provide their own police and other optional services. A hamlet is a populated area within a town that is not part of a village. The term "hamlet" is not defined under New York law (unlike cities, towns and villages), but is often used in the state's statutes to refer to well-known populated sections of towns that are not incorporated as villages.
