Criticise umpire’s verdict to prove successful? (3,3)
I believe the answer is:
pan out
'prove successful?' is the definition.
(I've seen this in another clue)
'criticise umpire's verdict' is the wordplay.
'criticise' becomes 'pan' (informal term meaning to criticise heavily).
'umpire's verdict' becomes 'out' (I am not sure about this - if you are sure you should believe this answer much more).
'pan'+'out'='PAN OUT'
'to' is the link.
Can you help me to learn more?
(Other definitions for pan out that I've seen before include "Have acceptable result - exclude frying vessel" , "Conclude, end up well" , "End up, turn out well" .)
