Better to accept European doctor (6)
I believe the answer is:
healer
'doctor' is the definition.
(I've seen this in another clue)
'better to accept european' is the wordplay.
'better' becomes 'haler' (more hale - healthy).
'to accept' indicates putting letters inside.
'european' becomes 'E' (abbreviation e.g. EU).
'haler' placed around 'e' is 'HEALER'.
(Other definitions for healer that I've seen before include "One who cures through medicine or faith" , "doctor!" , "One should put her right" , "Person with gift of curing illness" , "One restoring to health" .)
