Intertwine in dance (5)
I believe the answer is:
twist
I believe this is a double definition.
'intertwine' is the first definition.
(I know that intertwine is a more specific form of the action twist)
'dance' is the second definition.
(I know that twist is a more specific form of the action dance)
'in' acts as a link.
(Other definitions for twist that I've seen before include "Sixties dance; cheat" , "Spiral" , "Change of direction" , "See Oliver" , "Unexpected development of events" .)
