In the kitchen, this helps if you can't spell too well after a drink (3,5)
I believe the answer is:
tea towel
'in the kitchen this helps if you can't spell' is the definition.
The definition suggests a singular noun which matches the answer.
'too well after a drink' is the wordplay.
'too well' becomes 'towel' (I can't explain this - if you can you should give a lot more credence to this answer).
'after' says to put letters next to each other.
'a drink' becomes 'tea' (tea is a drink).
'towel' put after 'tea' is 'TEA-TOWEL'.
Can you help me to learn more?
(Other definitions for tea towel that I've seen before include "Cloth for wiping up" , "Washing-up drier" , "Kitchen drier" , "kitchenalia" , "Kitchen cloth" .)
