She's back, more than half asleep (4)
I believe the answer is:
elsa
'she's' is the definition.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for elsa that I've seen before include "Girl" , "___ Schiaparelli, Italian-born French fashion designer d. 1973" , "Big cat" , "Famous lioness" , "Lioness (born free in Kenya)" .)
