Remedy in pot excellent one (7)
I believe the answer is:
panacea
'remedy' is the definition.
(I know that panacea is a type of remedy)
'in pot excellent one' is the wordplay.
'in pot' becomes 'pan' (I've seen this in other clues. I am not sure about the 'in' bit.).
'excellent' becomes 'ace' (I've seen this before).
'one' becomes 'a' (a thing is one thing).
'pan'+'ace'+'a'='PANACEA'
Can you help me to learn more?
(Other definitions for panacea that I've seen before include "comprehensive fix" , "Universal medicine" , "Cure-all in a canape" , "A cure-all for diseases or troubles" , "Cure for all ills" .)
