Islet

Definitions vary, and are not precise, but some suggest that an islet is a very small, often unnamed, island with little or no vegetation to support human habitation.

It may be made of rock, sand and/or hard coral; may be permanent or tidal (i.e. surfaced reef or seamount); and may exist in the sea, lakes, rivers or any other sizeable bodies of water.

As suggested by its origin islette, an Old French diminutive of "isle",[2] use of the term implies small size, but little attention is given to drawing an upper limit on its applicability.

The World Landforms website says, "An islet landform is generally considered to be a rock or small island that has little vegetation and cannot sustain human habitation", and further that size may vary from a few square feet to several square miles, with no specific rule pertaining to size.

One long-term dispute over the status of such an islet was that of Snake Island (Black Sea).
