Picturing parts of a city (5)
I believe the answer is:
turin
'a city' is the definition.
(I know that Turin is a city)
'picturing parts' is the wordplay.
'parts' says the answer is hidden in the clue (part of the clue provides the answer).
'TURIN' can be found hidden inside 'picturing'.
'of' acts as a link.
(Other definitions for turin that I've seen before include "First capital in 1861 of united Italy" , "City abroad" , "foreign city" , "First capital of a united Italy, 1861-65" , "Italian location" .)
