Choice words from ad agency (5)
I believe the answer is:
adage
'choice words' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe there's a link between them I don't understand?
'ad agency' is the wordplay.
'agency' becomes 'age' (I can't justify this - if you can you should believe this answer much more).
'ad'+'age'='ADAGE'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for adage that I've seen before include "Saw, proverb" , "Old saw" , "Well-remembered proverb or saying" , "Axiom" , "Saying, saw" .)
