"Hear me out” (6)
I believe the answer is:
listen
'hear me out' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for listen that I've seen before include "Try to hear (something)" , "Attend (to a sound)" , "Respond (to advice)" , "Take heed -- 13 (anag)" , "Make an effort to hear" .)
