Etymology

Origin of island

First recorded before 900; Middle English iland, Old English īgland, īland, variant of īegland, from īeg “island” (cognate with Old Norse ey ) + land land; spelling with -s- by association with isle

Explanation

An island is a piece of land that is surrounded on all sides by water. Some islands are so small that a beach chair and umbrella barely fit on them and some are big enough to contain a whole nation. To get to an island you must take a boat, bridge or airplane — be a strong swimmer. If you can get there by land it’s not an island, though it may be a peninsula, like Florida. There are many famous islands, like Manhattan and the islands of Hawaii. Things that are free-standing can also be called islands, like the island made of cabinets and a counter that is found in some kitchens — it's not connected to anything else.
