Small body of land (5)
I believe the answer is:
islet
'small body of land' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for islet that I've seen before include "Cay, for example" , "A small piece of territory" , "Small landmass" , "Tiles (anag.)" , "small key?" .)
