Give up on eating small pudding (7)
I believe the answer is:
dessert
'pudding' is the definition.
(I've seen this before)
'give up on eating small' is the wordplay.
I cannot really see how this works, but
'small' could be 's' (abbreviation - e.g. clothes size) and 's' is found in the answer.
The remaining letters 'desert' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for dessert that I've seen before include "Sweet, afters" , "Fool possibly" , "Charlotte maybe" , "Christmas pudding maybe" , "Sweet, last course of a meal" .)
