Don't go on stage (4)
I believe the answer is:
stop
This clue might be a double definition.
'don't go' is the first definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe there's a link between them I don't understand?
'stage' is the second definition.
(thesaurus)
'on' acts as a link.
Can you help me to learn more?
(Other definitions for stop that I've seen before include "colon, say" , "Come to an end" , "Blockage" , "Knock out" , "Pause - prevent" .)
