Tell me, using your brain, best sock (3,4,2)
I believe the answer is:
out with it
'tell me' is the definition.
(I've seen this before)
'your brain best sock' is the wordplay.
I cannot quite understand how this works, but
'brain' could be 'wit' (synonyms) and 'wit' is present in the answer.
'sock' could be 'hit' (I've seen this before) and 'hit' is located in the answer.
The remaining letters 'out' 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).
'using' acts as a link.
Can you help me to learn more?
(Other definitions for out with it that I've seen before include "Speak up" , "Say what you think" , "Go on" , "Tell me quickly" , "Demand for comment" .)
