How expert in judo is beaten (6)
I believe the answer is:
belted
'beaten' is the definition.
(I've seen this before)
'how expert in judo is' is the wordplay.
I cannot really see how this works, but
'is' could be 'be' and 'be' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for belted that I've seen before include "beaten" , "Dealt a heavy blow" , "Hit very hard; done up" , "Ran furiously" , "as an earl may be" .)
