New dances take off (6)
I believe the answer is:
ascend
'take off' is the definition.
(I've seen this before)
'new dances' is the wordplay.
'new' indicates an anagram.
'dances' is an anagram of 'ASCEND'.
(Other definitions for ascend that I've seen before include "Travel upwards" , "Mount" , "Climb, go up (6)" , "Move upwards" , "rise in status" .)
