Anna's sister in "Frozen" (4)
I believe the answer is:
elsa
'anna's sister in frozen' 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 "Girl" , "Famous lioness" , "Big cat" , "___ Schiaparelli, Italian-born French fashion designer d. 1973" , "Lioness (born free in Kenya)" .)
