Four notes about a private meeting (4-1-4)
I believe the answer is:
tete-a-tete
'a private meeting' is the definition.
(I've seen this before)
'four notes' is the subsidiary indication.
I cannot quite see how this works, but
'notes' could be 'ea' and 'ea' is present in the answer.
This may be the basis of clue (or it may be nonsense).
'about' is the link.
Can you help me to learn more?
(Other definitions for tete-a-tete that I've seen before include "Private couple's conversation" , "Informal chat" , "One-to-one meeting" , "Private conversation between two French people" , "Private conversation between two people as in France" .)
