Dance presented outside lacking restraint (7)
I believe the answer is:
gavotte
'dance' is the definition.
(I know that gavotte is an Folk dance)
'presented outside lacking restraint' is the wordplay.
'presented' becomes 'gave' ('give' can be a synonym of 'present').
'outside' indicates putting letters inside.
'lacking restraint' becomes 'ott' (I am not sure about this - if you are sure you should believe this answer much more).
'gave' going around 'ott' is 'GAVOTTE'.
Can you help me to learn more?
(Other definitions for gavotte that I've seen before include "Tag vote (anag) - dance" , "merry dance" , "Dance of French origin" , "steps taken" , "Former French dance" .)
