Good man attends fourth match (7)
I believe the answer is:
benefit
'good' is the definition.
(I know that benefit is a type of good)
'man attends fourth match' is the wordplay.
'man' becomes 'ben' ().
'attends fourth' becomes 'e' (4th letter of 'attends').
'match' becomes 'fit' (synonyms).
'ben'+'e'+'fit'='BENEFIT'
(Other definitions for benefit that I've seen before include "Handout" , "allowance" , "Payment" , "Advantage or blessing" , "Something that aids" .)
