Berated, possibly, by one who's disposed to argue? (7)
I believe the answer is:
debater
'one who's disposed to argue?' is the definition.
I can't tell whether this defines the answer.
'berated possibly' is the wordplay.
'possibly' is an anagram indicator.
'berated' anagrammed gives 'DEBATER'.
'by' is the link.
Can you help me to learn more?
(Other definitions for debater that I've seen before include "speaker at Oxford Union" , "One arguing" , "One engaged in public argument" , "argumentative person" , "disputatious type" .)
