Skye, eg (4)
I believe the answer is:
isle
'skye eg' is the definition.
(I know that Isle of Skye is a isle)
This is the entire clue.
(Other definitions for isle that I've seen before include "Sheppey, perhaps" , "Skye, for example" , "isolated spot" , "Small mass of land in the sea" , "Anglesey, say" .)
