Part of MFA (4)
I believe the answer is:
arts
'part of mfa' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for arts that I've seen before include "Non-science subjects" , "Eg, painting, sculpture" , "Wiles, skills" , "Aesthetic pursuits for rats" , "Drawing, painting, etc" .)
