Ref not quite in time for match (5)
I believe the answer is:
agree
'match' is the definition.
(as in two tallies agreeing or matching)
'ref not quite in time' is the wordplay.
'not quite' means to remove the last letter (most but not all of the word).
'in' is an insertion indicator.
'time' becomes 'age' (an age is a period of time).
'ref' with its final letter taken away is 're'.
're' placed within 'age' is 'AGREE'.
'for' acts as a link.
(Other definitions for agree that I've seen before include "Give consent" , "Square" , "Match; tally" , "Enjoy view in common" , "Allow" .)
