Confronted viewer and shouted to the audience (9)
I believe the answer is:
eyeballed
'confronted' is the definition.
(I've seen this before)
'viewer and shouted to the audience' is the wordplay.
'viewer' becomes 'eye' (organ which sees or views).
'and' says to put letters next to each other.
'shouted' becomes 'bawled' (I've seen this before).
'to the audience' indicates a 'sounds like' (homophone) clue.
'bawled' sounds like 'balled'.
'eye'+'balled'='EYEBALLED'
(Other definitions for eyeballed that I've seen before include "confronted" , "Stared at" , "Watched" , "looked at" .)
