It's all over a point in the revised deed (5)
I believe the answer is:
ended
'it's all over' is the definition.
(synonyms)
'a point in the revised deed' is the wordplay.
'a point' becomes 'N' (North).
'in the' indicates putting letters inside.
'revised' is an anagram indicator.
'deed' anagrammed gives 'eded'.
'n' going inside 'eded' is 'ENDED'.
(Other definitions for ended that I've seen before include "Broke off; finished" , "Brought to a close" , "Done" , "Finished, terminated" , "Acclaim" .)
