Make better priest in Paris (4)
I believe the answer is:
cure
This clue might be a double definition.
'make better' is the first definition.
(as in making a patient better)
'priest in paris' is the second definition.
'cure' can be an answer for 'priest' ('priest' in French). I'm not sure about the 'in paris' bit.
Can you help me to learn more?
(Other definitions for cure that I've seen before include "Treat - French parish priest" , "Preserve by smoking - make better" , "Heal or preserve" , "Heal or pickle" , "Foreign priest" .)
