Foreign and possibly coming to heel (5)
I believe the answer is:
cuban
'heel' is the definition.
(Cuban heel is an example)
'foreign and possibly' is the wordplay.
I cannot really understand how this works, but
'and' could be 'n' (common abbreviation for 'and') and 'n' is found within the answer.
The remaining letters 'cuba' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'coming to' is the link.
Can you help me to learn more?
(Other definitions for cuban that I've seen before include "Caribbean" , "Relating to Castro's isle" , "Expensive kind of cigar" , "islander" , "Like Fidel Castro" .)
