More excited by city (4)
I believe the answer is:
rome
'city' is the definition.
(Rome is an example)
'more excited' is the wordplay.
'excited' is an anagram indicator.
'more' with letters rearranged gives 'ROME'.
'by' is the link.
(Other definitions for rome that I've seen before include "Capital of Italy" , "European capital" , "All roads lead to it" , "Spanish Steps city" , "City not built in a day" .)
