Blunt answer's received about legislative measure (5,10)
I believe the answer is:
joint resolution
'received about legislative measure' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe there's an association between them I don't understand?
'blunt answer's' is the wordplay.
'blunt' becomes 'joint' (I can't explain this - if you can you should believe this answer much more).
'answer' becomes 'resolution' (synonyms).
'joint'+'resolution'='JOINT RESOLUTION'
Can you help me to learn more?
(Other definitions for joint resolution that I've seen before include "showing firmness on cannabis" , "United congressional action" .)
