Disney snow queen (4)
I believe the answer is:
'disney snow queen' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for elsa that I've seen before include "Big cat" , "Famous lioness" , "Lioness (born free in Kenya)" , "___ Schiaparelli, Italian-born French fashion designer d. 1973" , "Girl" .)
