"Born Free" character (4)
I believe the answer is:
elsa
'born free character' 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 "Famous lioness" , "Girl" , "Lioness (born free in Kenya)" , "___ Schiaparelli, Italian-born French fashion designer d. 1973" , "Big cat" .)
