Say a supporter gets beer all round (6)
I believe the answer is:
allege
'say' is the definition.
(synonyms)
'a supporter gets beer all round' is the wordplay.
'a supporter' becomes 'leg' (I've seen this in another clue).
'gets beer' becomes 'ale' (I can't explain this - if you can you should give a lot more credence to this answer).
'all round' is an insertion indicator.
'leg' going inside 'ale' is 'ALLEGE'.
Can you help me to learn more?
(Other definitions for allege that I've seen before include "Make accusation without proof" , "Claim, suggest" , "Declare without actual proof" , "hold" , "Declare or accuse without proof" .)
