Back with a little less than a dollar from abroad (4)
I believe the answer is:
cuba
'little less than a dollar from abroad' is the definition.
I can't judge whether this defines the answer.
'back with a' is the wordplay.
'back' becomes 'cub' (I can't justify this - if you can you should give a lot more credence to this answer).
'with' says to put letters next to each other.
'cub'+'a'='CUBA'
Can you help me to learn more?
(Other definitions for cuba that I've seen before include "Caribbean nation" , "Island nation" , "Guantanamo Bay island" , "Island N. of Jamaica" , "Caribbean island republic" .)
