Feature, part of inglenook (4)
I believe the answer is:
glen
'feature part' is the definition.
The definition and answer can be both natural objects as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'of inglenook' is the wordplay.
'of' indicates a hidden word.
'GLEN' is hidden within 'inglenook'.
Can you help me to learn more?
(Other definitions for glen that I've seen before include "Valley, dale" , "Scottish mountain valley" , "Narrow Scots valley" , "Depression in Scotland" , "Narrow secluded valley in mountains" .)
