Wager gets everyone to dance (6)
I believe the answer is:
ballet
'dance' is the definition.
(ballet is a kind of dance)
'wager gets everyone' is the wordplay.
'wager' becomes 'bet' ('bet' can be a synonym of 'wager'**).
'gets' indicates putting letters inside (gets can mean captures or absorbs).
'everyone' becomes 'all' (I've seen this before).
'bet' placed around 'all' is 'BALLET'.
'to' is the link.
(Other definitions for ballet that I've seen before include "kind of skirt" , "Dance entertainment" , "Let lab open up for dance" , "Eg, Swan Lake" , "Theatrical dance" .)
