A dancing turn? (5)
I believe the answer is:
twist
This clue is a double definition.
'a dancing' is the first definition.
(I know that Twist is a type of dancing)
'turn?' is the second definition.
(I know that turn can be written as twist)
(Other definitions for twist that I've seen before include "surprising plot development" , "Rotate rapidly" , "Writhe" , "Wring" , "Change - 1960s' dance" .)
