US city supporting couple — right that, not half! (4,5)
I believe the answer is:
fort worth
'us city' is the definition.
(I've seen this before)
'supporting couple right that not half' is the wordplay.
'supporting' becomes 'for'.
'couple' becomes 'two' (I've seen this before).
'right' becomes 'rt'.
'that not half' becomes 'h' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'for'+'two'+'rt'+'h'='FORT WORTH'
Can you help me to learn more?
(Other definitions for fort worth that I've seen before include "Texas city" , "US city" .)
