Largest of the Inner Hebrides (4)
I believe the answer is:
skye
'largest of the inner hebrides' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for skye that I've seen before include "Inner Hebridean isle" , "Large Scottish island" , "Largest Inner Hebridean island" , "Largest island of Scotland's Inner Hebrides" , "Portree's isle" .)
