Leave quietly, no time for pleasantry (4)
I believe the answer is:
quip
This might be a double definition.
'leave quietly no time' is the first definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'pleasantry' is the second definition.
(thesaurus)
'for' acts as a link.
Can you help me to learn more?
(Other definitions for quip that I've seen before include "Brief witty saying" , "Wisecrack" , "Quick joke" , "Bon mot" , "Crack" .)
