Land surrounded by water is an island . You are describing a peninsula.
An island is a piece of land entirely surrounded by water.
That depends on whether the land is surrounded by water or something else. If it is surrounded by water, it is an island. If it is surrounded by water but is sufficiently large, it may be called an island continent (an example is Australia). If it is a land area completely surrounded by high mountains, rivers will flow to the land that is surrounded instead of to the ocean in that area. That would make the land an endorrheic basin.
