Where barristers practise drinking (2,3,3)
I believe the answer is:
at the bar
'practise drinking' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'where barristers' is the wordplay.
I cannot really understand how this works, but
'barristers' could be 'thebar' (term for the legal profession) and 'thebar' is found in the answer.
The remaining letters 'at' 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?
(Another definition for at the bar that I've seen is " "Prisoner _______ "".)
