Professional journalist from Central Europe? (8)
I believe the answer is:
polished
'professional' is the definition.
(thesaurus)
'journalist from central europe?' is the wordplay.
I cannot really understand how this works, but
'journalist' could be 'ed' (short for editor) and 'ed' is found within the answer.
The remaining letters 'polish' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
(Other definitions for polished that I've seen before include "Difference, statistical quantity" , "Genteel - flawless" , "Shining or refined" , "Made shiny and smooth" , "Shiny; rubbed" .)
