Enjoy view in common — area with endless grassy plot (5)
I believe the answer is:
agree
'enjoy view in common' is the definition.
(I've seen this before)
'area with endless grassy plot' is the wordplay.
'area' becomes 'a' (maths abbreviation).
'with endless grassy plot' becomes 'gree' (I can't justify this - if you can you should believe this answer much more).
'a'+'gree'='AGREE'
Can you help me to learn more?
(Other definitions for agree that I've seen before include "Concur - correspond" , "Consent required" , "Accord, match" , "Shake on it" , "Have the same opinion" .)
