Person tending to accept European job (6)
I believe the answer is:
career
'job' is the definition.
(someone's occupation)
'person tending to accept european' is the wordplay.
'person tending' becomes 'carer' (someone tending to patients).
'to accept' means one lot of letters goes inside another.
'european' becomes 'E' (abbreviation e.g. EU).
'carer' placed around 'e' is 'CAREER'.
(Other definitions for career that I've seen before include "Business course through life" , "go very fast" , "Dash - profession" , "Run - profession" , "Life (in terms of work etc)" .)
