Tear into specialist with a claim to cure everything (7)
I believe the answer is:
panacea
'tear' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'specialist with a claim to cure everything' is the wordplay.
I cannot quite see how this works, but
'a' could be 'an' and 'an' is located in the answer.
This explanation may well be incorrect...
'into' acts as a link.
Can you help me to learn more?
(Other definitions for panacea that I've seen before include "Cure for all ills" , "comprehensive fix" , "Solution to all difficulties" , "Cure for all things" , "that can make anything better" .)
