Lies about a piece of land (4)
I believe the answer is:
isle
'a piece of land' is the definition.
(I've seen this before)
'lies about' is the wordplay.
'about' is an anagram indicator.
'lies' with letters rearranged gives 'ISLE'.
(Other definitions for isle that I've seen before include "small piece of land" , "Small area of ground" , "Body of land surrounded by water" , "Skye, for instance" , "A poetic island" .)
