Majors in acting (3)
I believe the answer is:
lee
'majors in acting' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for lee that I've seen before include "Shelter" , "Bruce ___, martial arts ace" , "Area sheltered from the wind" , "Sheltered from the wind in Cork, perhaps" , "Revolutionary general" .)
