A grassy area cut short for match (5)
I believe the answer is:
agree
'match' is the definition.
(agreeing is a kind of matching)
'a grassy area cut short' is the wordplay.
'grassy area' becomes 'green' (I've seen this before).
'cut short' means to remove the last letter.
'green' with its last letter taken away is 'gree'.
'a'+'gree'='AGREE'
'for' is the link.
(Other definitions for agree that I've seen before include "Shake on it" , "confess?" , "concede" , "Go along with" , "Be of one mind" .)
