Summit scoffed about British being bullied (10)
I believe the answer is:
browbeaten
'being bullied' is the definition.
('browbeaten' can be a synonym of 'bullied')
'summit scoffed about british' is the wordplay.
I cannot quite see how this works, but
'summit' could be 'brow' (brow is a kind of summit) and 'brow' is present in the answer.
'scoffed' could be 'eaten' (I've seen this before) and 'eaten' is present in the answer.
'british' could be 'b' (abbreviation e.g. in BBC) and 'b' is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for browbeaten that I've seen before include "Bullied" , "Intimidated" .)
