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.
Outer Lands
Long Island is often informally considered a part of the "New York islands", together with Staten Island and Manhattan. These islands are geographically contiguous with the broader region. (The insular Massachusetts sections were actually part of the Province of New York for most of the late 17th century.)
