Exclusive helping of ice cream (5)
I believe the answer is:
scoop
'exclusive' is the definition.
(as in a newspaper scoop)
'helping of ice cream' is the wordplay.
I cannot quite understand how this works, but
'of' could be 'o' and 'o' is found within the answer.
The remaining letters 'scop' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for scoop that I've seen before include "war novel" , "Reporting exclusive" , "Exclusive news story" , "Type of ladle" , "Piece of news that no-one else has" .)
