Female who’s good at spelling? (5)
I believe the answer is:
witch
'female' is the definition.
(witch is a kind of female)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for witch that I've seen before include "Female sorcerer" , "One of a coven" , "Female member of coven" , "... and magician" , "'The Lion, the - - and the Wardrobe'" .)
