A healer whose patients may be spellbound (5,6)
I believe the answer is:
witch doctor
'a healer' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe you can see a link between them that I don't see?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for witch doctor that I've seen before include "Tribal magician" , "Shaman" , "Medicine man" .)
