Audition, with "out" (3)
I believe the answer is:
try
'audition with out' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for try that I've seen before include "Attempt; smooth (wood)" , "Make an effort to get rugby score" , "Make severe demands on" , "Attempt a score" , "shot" .)
