Figure-skating feat (4)
I believe the answer is:
axel
'figure-skating feat' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for axel that I've seen before include "Skating jump involving a mid-air turn" , "What skater may do" , "Manoeuvre by skater" , "Figure skater's jump" , "Figure-skating jump" .)
