Sophistication (8)
I believe the answer is:
urbanity
'sophistication' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for urbanity that I've seen before include "Elegance or sophistication in appearance" , "Suave, polished manner" , "Suave nature" , "showing sophistication" , "Refined quality - but rainy (anag)" .)
