Well-spoken couple (10)
I believe the answer is:
articulate
This clue is a double definition.
'well-spoken' is the first definition.
('articulate' can be similar in meaning to 'well-spoken')
'couple' is the second definition.
(thesaurus)
(Other definitions for articulate that I've seen before include "Talk" , "Provide joint" , "Express coherently" , "Clearly stating view" , "split into clearly distinct parts" .)
