Blimey, a funny magician! (6)
I believe the answer is:
cooper
'funny magician' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'blimey a' is the wordplay.
'blimey' becomes 'coo' (both are expressions of surprise).
'a' becomes 'per' (eg 'one a day' means 'one per day').
'coo'+'per'='COOPER'
Can you help me to learn more?
(Other definitions for cooper that I've seen before include "Cask-maker" , "supplier of stiffeners?" , "Craftsman" , "Barrel-maker" , "Cask/barrel maker" .)
