Dramatic utterances actors can’t hear? (6)
I believe the answer is:
asides
'dramatic utterances' is the definition.
The definition and answer can be both related to communication as well as being plural nouns.
Perhaps there's an association between them I don't understand?
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for asides that I've seen before include "Remarks not for overhearing" , "throwaway comments" , "Words spoken on stage" , "communications not intended for everyone" , "Incidental remarks" .)
