Humour with husband sent packing (3)
I believe the answer is:
wit
'humour' is the definition.
(synonyms)
'with husband sent packing' is the wordplay.
I cannot quite understand how this works, but
'with' could be 'w' (abbreviation) and 'w' is found in the answer.
The remaining letters 'it' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for wit that I've seen before include "Funny person" , "Intelligence; humorous person" , "Clever humour in speech" , "Humour or common sense" , "Form of humour" .)
