Inaccurately claimed to be curative (7)
I believe the answer is:
medical
'be curative' is the definition.
Both the answer and definition are adjectives. Maybe you can see an association between them that I don't see?
'inaccurately claimed' is the wordplay.
'inaccurately' indicates anagramming the letters.
'claimed' anagrammed gives 'MEDICAL'.
'to' is the link.
Can you help me to learn more?
(Other definitions for medical that I've seen before include "Relating to the art of healing" , "Health check-up" , "Relating to treatment rather than surgery" , "Thorough health check" , "Claimed (anag.)" .)
