Wager everything included in dancing entertainment (6)
I believe the answer is:
ballet
'dancing entertainment' is the definition.
'ballet' can be an answer for 'entertainment' (I have seen 'Theatrical entertainment' mean 'ballet' so perhaps 'entertainment' could also mean 'ballet'). I am not certain of the 'dancing' bit.
'wager everything included' is the wordplay.
'wager' becomes 'bet' (synonyms).
'everything' becomes 'all' (all things).
'included' indicates putting letters inside.
'bet' going around 'all' is 'BALLET'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for ballet that I've seen before include "Classical dance form" , "Art of the Kirov or Bolshoi" , "Let lab open up for dance" , "The theatre of dance" , "Story performed to music by dancers" .)
