Go round as a music hall act (4)
I believe the answer is:
turn
This clue is a quadruple definition!!
'go' is the first definition.
(as in one's go or turn in a game)
'round' is the second definition.
(synonyms)
'as' is a link.
'a music hall' is the third definition.
The definition and answer can be both related to communication as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'act' is the fourth definition.
(theatre)
Can you help me to learn more?
(Other definitions for turn that I've seen before include "Go off - act" , "Shape (using a lathe)" , "Move in a new direction" , "Distinctive expression" , "Go - short walk" .)
