Tiny couple twists at the end of dance (6)
I believe the answer is:
minute
'tiny' is the definition.
(I've seen this before)
'couple twists at the end of dance' is the wordplay.
I cannot really understand how this works, but
'at' could be 'in' and 'in' is found within the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found within the answer.
This may be the basis of clue (or it may be nonsense).
(Other definitions for minute that I've seen before include "Tiny - proportion of time" , "Occupying very little space" , "It's not very long" , "Small amount of time" , "Sixty seconds" .)
