Approved finale with men O'Connor maybe brought over (8)
I believe the answer is:
endorsed
'approved' is the definition.
(endorsing is a kind of approving)
'finale with men o'connor maybe brought over' is the wordplay.
I cannot really understand how this works, but
'finale' could be 'end' (I've seen this before) and 'end' is found within the answer.
'men' could be 'se' (I have seen 'Spanish men ' mean 'se' so perhaps 'men' could also mean 'se') and 'se' is found in the answer.
'over' could be 'o' (cricket abbreviation) and 'o' is found within the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for endorsed that I've seen before include "Seconded" , "Publicly approved" , "Formally backed" , "Officially approved" , "Approved and backed" .)
