Some turning up in Slovenian or even Italian city (6)
I believe the answer is:
verona
'italian city' is the definition.
(I've seen this before)
'some turning up in slovenian or even' is the wordplay.
'turning up in' says the letters should be written backwards.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'anorev' is hidden within 'slovenian or even'.
'anorev' back-to-front is 'VERONA'.
(Other definitions for verona that I've seen before include "Italian city (with two gentlemen)" , "Where 27 [MERCUTIO] was killed" , "Rave on in Italian city of Romeo and Juliet" , "Home town of Romeo and Juliet" , "Italian city, home of Romeo and Juliet" .)
