Lies about some land (4)
I believe the answer is:
Here is my best explanation:
'some land' is the definition.
(isle is a kind of land)
'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 "Geographic location", "Island", "Small region of land", "Said of Sheppey, Dogs, Wight or Man?", "One surrounded by water", "Small area of ground", "Of Man or Youth, for example", "Atoll", "small area of land" and "Man, for one".)
