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