Novel personality (9)
I believe the answer is:
character
This might be a double definition.
'novel' is the first definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'personality' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for character that I've seen before include "Personal moral qualities" , "Distinctive nature" , "strength of mind" , "Someone in play" , "Person in a play; letter" .)
