"Frozen" character who sings "Let It Go" (4)
I believe the answer is:
elsa
'frozen character who sings let it go' 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" , "Girl" , "Famous lioness" , "Lioness (born free in Kenya)" , "___ Schiaparelli, Italian-born French fashion designer d. 1973" .)
