Medic with a degree works in theatre (5)
I believe the answer is:
drama
'works in theatre' is the definition.
(theatrical works)
'medic with a degree' is the wordplay.
'medic' becomes 'dr' (doctor).
'with' says to put letters next to each other.
'degree' becomes 'ma' (Master of Arts is a type of degree).
'dr'+'a'+'ma'='DRAMA'
(Other definitions for drama that I've seen before include "theatre production" , "Theatrical play" , "Play; exciting situation" , "Theatre or radio play" , "show of histrionics" .)
