Acknowledgement of how Bond became good in France (3)
I believe the answer is:
'acknowledgement' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Perhaps there's an association between them I don't understand?
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for nod that I've seen before include "Cain left Eden for the Land of . . ." , "Move head in assent" , "Indicate 25 [YES]" , "Doze" , "Brief bowing gesture" .)
