Something greater than family selection from menu (5)
I believe the answer is:
order
'menu' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps there's a link between them I don't understand?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for order that I've seen before include "Rank" , "Tidy state - that's a command" , "Instruct" , "Apply for - class" , "Command or request for goods" .)
