Stake about everything in a stage production (6)
I believe the answer is:
ballet
'a stage production' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'stake about everything' is the wordplay.
'stake' becomes 'bet' (synonyms).
'about' is an insertion indicator.
'everything' becomes 'all' (all things).
'bet' enclosing 'all' is 'BALLET'.
'in' is the link.
Can you help me to learn more?
(Other definitions for ballet that I've seen before include "Classical dancing style" , "Dance entertainment" , "Eg, Swan Lake" , "Dance art form" , "Let lab open up for dance" .)
