Refinement seen in Venice, typically (6)
I believe the answer is:
nicety
'refinement' is the definition.
(I know that refinement can be written as nicety)
'in venice typically' is the wordplay.
'in' says the answer is hidden in the clue.
'NICETY' is hidden within 'venice typically'.
'seen' is the link.
(Other definitions for nicety that I've seen before include "Minute distinction; subtlety" , "Matter of delicate adjustment" , "Finesse" , "Fine distinction" , "Small detail" .)
