Name, say, for maniac (6)
I believe the answer is:
nutter
'maniac' is the definition.
Both the definition and answer are singular nouns.
Perhaps there's a link between them I don't understand?
'name say' is the wordplay.
'name' becomes 'n' (common abbreviation e.g. on forms).
'say' becomes 'utter' (to utter something is to speak or say it).
'n'+'utter'='NUTTER'
'for' is the link.
Can you help me to learn more?
(Other definitions for nutter that I've seen before include "fruitcake" , "Madman" , "loony" , "psychopath" , "Lunatic (sl.)" .)
