Encourage awareness for the audience (6)
I believe the answer is:
incite
'encourage' is the definition.
(I've seen this before)
'awareness for the audience' is the wordplay.
'awareness' becomes 'insight' (I've seen this before).
'for the audience' indicates a 'sounds like' (homophone) clue.
'insight' is a homophone of 'INCITE'.
(Other definitions for incite that I've seen before include "Provoke to action" , "Arouse to action" , "Encourage, urge" , "Stir up, hatred say" , "Whip up" .)
