Poser resolved by new woman? (6)
I believe the answer is:
person
'poser' is the 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?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for person that I've seen before include "he's the third" , "character" , "See 17" , "anyone else" , "A man or woman" .)
