European editor describes sophisticated performance, maybe (8)
I believe the answer is:
polished
'sophisticated performance maybe' is the definition.
I can't judge whether this defines the answer.
'european editor' is the wordplay.
'european' becomes 'polish' (Poland is in Europe).
'editor' becomes 'ed' (abbreviation).
'polish'+'ed'='POLISHED'
'describes' is the link.
Can you help me to learn more?
(Other definitions for polished that I've seen before include "Shiny; rubbed" , "Genteel - flawless" , "Highly accomplished" , "Shining or refined" , "Made shiny and smooth" .)
