Professional brought off (12)
I believe the answer is:
accomplished
This might be a double definition.
'professional' is the first definition.
(I've seen this before)
'brought off' is the second definition.
The definition and answer can be both to do with social activities as well as being past participle verbs.
Perhaps there's an association between them I don't understand?
Can you help me to learn more?
(Other definitions for accomplished that I've seen before include "Performed - completed - with a high degree of skill" , "Having particular skills" , "Completed; skilful" , "Consummate" , "executed" .)
