Hebridean bunch of keys (4)
I believe the answer is:
skye
'hebridean bunch' is the definition.
The definition suggests a singular noun which matches the answer.
'of keys' is the wordplay.
'of' indicates anagramming the letters (the answer comes from or 'of' the letters).
'keys' anagrammed gives 'SKYE'.
Can you help me to learn more?
(Other definitions for skye that I've seen before include "Largest island of Scotland's Inner Hebrides" , "Largest isle of the Inner Hebrides" , "Portree's isle" , "Large Scottish island" , "Where Bonnie Prince Charlie fled after his defeat at Culloden" .)
