An islet (/ˈaɪ.lət/, EYE-lət) is generally a small island. Definitions vary and are not precise, but some suggest that an islet is a very small, often unnamed, island with little or no vegetation and unable to support human habitation. It may be made of rock, sand 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.
