Flat share slightly beyond cash, playing for nothing? (7)
I believe the answer is:
cohabit
'playing for nothing?' is the definition.
I can't judge whether this definition defines the answer.
'flat share slightly beyond cash' is the wordplay.
'flat share' becomes 'oh' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'slightly' becomes 'a bit' ('a bit' can mean 'slightly' or 'somewhat').
'beyond' means one lot of letters go next to another.
'cash' becomes 'c'.
'oh'+'abit'='ohabit'
'ohabit' put after 'c' is 'COHABIT'.
Can you help me to learn more?
(Other definitions for cohabit that I've seen before include "Share residence" , "Live together as unmarried couple" , "Share accommodation" , "Live together as husband and wife" , "What to do with partner" .)
