Did something on stage (5)
I believe the answer is:
acted
'did' is the definition.
(I've seen this in another clue)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for acted that I've seen before include "Behaved or played a part" , "did something!" , "appeared on stage" , "Trod the boards" , "Play a role" .)
