Evaluate a sketch show for the audience (6)
I believe the answer is:
review
'evaluate a sketch' is the definition.
'review' can be an answer for 'evaluate' (I've seen this in another clue). I am unsure of the 'a sketch' bit.
'show for the audience' is the wordplay.
'show' becomes 'revue' (revue is a kind of show).
'for the audience' shows a homophone (sound like) (how an audience might hear it).
'revue' is a homophone of 'REVIEW'.
Can you help me to learn more?
(Other definitions for review that I've seen before include "notice" , "Appraise critically" , "Critic's article" , "Report" , "Inspection" .)
