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' indicates anagramming the letters.
'more' with letters rearranged gives 'ROME'.
'by' acts as a 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" .)
