Claims drinks all round for a cricket side (7)
I believe the answer is:
alleges
'claims' is the definition.
(I've seen this in another clue)
'round for a cricket side' is the wordplay.
'round' means one lot of letters goes inside another.
'for a' becomes 'ales' (I can't explain this - if you can you should give a lot more credence to this answer).
'cricket side' becomes 'leg' (I've seen this before).
'ales' enclosing 'leg' is 'ALLEGES'.
'drinks all' is the link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for alleges that I've seen before include "Holds" , "Accuses without proof" , "States without proof" , "Declares to be the case without proof" , "Claims" .)
