Is she able to heal? (4)
I believe the answer is:
leah
'is she' is the definition.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for leah that I've seen before include "Jacob's first wife (Bible)" , "Jacob's first wife (Gen. 29)" , "She married Jacob" , "Jacobs first wife (Gen.29)" , "Hale (anag) - wife of Jacob" .)
