Desserts served at post wedding party? (6)
I believe the answer is:
afters
'desserts' is the definition.
(informal UK term for the course after a main meal)
'at post wedding party?' is the wordplay.
'at' says to put letters next to each other.
'post' becomes 'after' (the prefix 'post-' means 'after').
'wedding party?' becomes 's' (I can't explain this - if you can you should give a lot more credence to this answer).
'after' next to 's' is 'AFTERS'.
'served' is the link.
Can you help me to learn more?
(Other definitions for afters that I've seen before include "food for pudding" , "Tiramisu, possibly" , "Sweet course" , "Dessert, sweet" , "Informal desserts may be faster" .)
