Take in side-splitting show, just new (5)
I believe the answer is:
house
'take in' is the definition.
(thesaurus)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for house that I've seen before include "Abode" , "Residence, dwelling" , "Company; dwelling" , "Building for dwelling in" , "Game; theatre; institution" .)
