Ask celebrity nut about comforter (8,7)
I believe the answer is:
security blanket
'comforter' is the definition.
I know nothing about this answer so I can't judge whether this works.
'ask celebrity nut about' is the wordplay.
'about' indicates an anagram.
'ask'+'celebrity'+'nut'='askcelebritynut'
'askcelebritynut' anagrammed gives 'SECURITY BLANKET'.
Can you help me to learn more?
(Other definitions for security blanket that I've seen before include "information blackout" , "comforter for child" , "could relieve child's anxiety" , "comforting to the young?" , "child's favourite recourse" .)
