The largest island of the Inner Hebrides (4)
I believe the answer is:
skye
'the largest island 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 "Largest island of Scotland's Inner Hebrides" , "somewhere off Scotland's west coast" , "Scots isle" , "Scot. island, toll bridge" , "Home of the Cuillin mountains" .)
