Regularly flaunt variable jump on ice (4)
I believe the answer is:
lutz
'jump on ice' is the definition.
'lutz' can be an answer for 'jump' (I've seen this before). I am unsure of the 'on ice' bit.
'regularly flaunt variable' is the wordplay.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
'variable' becomes 'z' (algebra).
The alternate letters of 'flaunt' are 'lut'.
'lut'+'z'='LUTZ'
Can you help me to learn more?
(Other definitions for lutz that I've seen before include "Figure skating jump with turns" , "Jump from one 5 down to the other" , "difficult skating manoeuvre?" , "Figure skating movement" .)
