Part of something said before going to meeting (4)
I believe the answer is:
agma
'part' is the definition.
Both the definition and answer are singular nouns.
Maybe they are linked in a way I don't understand?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for agma that I've seen before include "final sound of shouting or swearing?" , "conclusion of something to do with pronunciation" , "sounds nasal" , "Lettered symbol" .)
