Have fun in piece of theatre (4)
I believe the answer is:
play
This could be a double definition.
'have fun' is the first definition.
(I've seen this in another clue)
'piece of theatre' is the second definition.
'play' can be an answer for 'piece' (thesaurus). I am not sure about the 'of theatre' bit.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for play that I've seen before include "Have fun -- theatrical work" , "Portray in a drama" , "Theatrical performance" , "Frolic" , "Slack - performance" .)
