University church among least decorated in the city (9)
I believe the answer is:
bucharest
'city' is the definition.
(Bucharest is an example)
'university church among least decorated in' is the wordplay.
'university' becomes 'U' (abbreviation as in UMass).
'church' becomes 'ch' (common abbreviation).
'among' says to put letters next to each other.
'least decorated' becomes 'barest' (I've seen this in another clue).
'in' is an insertion indicator.
'u'+'ch'='uch'
'uch' placed into 'barest' is 'BUCHAREST'.
'the' is the link.
(Other definitions for bucharest that I've seen before include "Capital of Romania" , "European city" , "European capital" , "Balkan city" , "Romanian capital" .)
