Broadcast agreed for all to hear? (5)
I believe the answer is:
aloud
'for all to hear?' is the definition.
(audible by whoever's around)
'broadcast agreed' is the wordplay.
'broadcast' indicates a 'sounds like' (homophone) clue (how the word might sound on the radio or TV).
'agreed' becomes 'allowed'.
'allowed' sounds like 'ALOUD'.
(Other definitions for aloud that I've seen before include "Not silently or in a whisper" , "it is said" , "Not sotto voce" , "So as to be heard" , "Not under breath" .)
