Man, with hesitation, embracing cold ballerina (6)
I believe the answer is:
dancer
'ballerina' is the definition.
(I've seen this in another clue)
'man with hesitation embracing cold' is the wordplay.
'man' becomes 'dan' ().
'with' is a charade indicator (letters next to each other).
'hesitation' becomes 'er' (sound made while hesitating - um, er).
'embracing' is an insertion indicator.
'cold' becomes 'C' (eg on taps).
'dan'+'er'='daner'
'daner' placed around 'c' is 'DANCER'.
(Other definitions for dancer that I've seen before include "One moves to music" , "One of Santa's reindeer" , "See 25" , "behind Rudolph" , "One in the same team as, say, Rudolf" .)
