Daddy's dance (3)
I believe the answer is:
pas
I believe this clue is a double definition.
'daddy's' is the first definition.
(I know this)
'dance' is the second definition.
(I've seen this before)
(Other definitions for pas that I've seen before include "Dance step" , "Dad's" , "Office workers" , "... de deux, ballet step for two" , "Type of sausage" .)
