The French connection? (7)
I believe the answer is:
liaison
This might be a double definition.
'the french' is the first definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe there's a link between them I don't understand?
'connection?' is the second definition.
(I've seen this in another clue)
Can you help me to learn more?
(Other definitions for liaison that I've seen before include "Usually secretive or illicit relationship" , "Secretive affair" , "Mil. coordination; illicit affair" , "Illicit romance" , "Mutual communication and co-operation" .)
