Lordly name? (5)
I believe the answer is:
title
'lordly name?' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Maybe they are linked in a way I don't understand?
This is the entire clue.
Can you help me to learn more?
(Other definitions for title that I've seen before include "Proprietorship" , "inscription" , "Name - legal right" , "headline?" , "Deed showing legal right to a property" .)
