City suffering torn parts excessively (7)
I believe the answer is:
toronto
'city' is the definition.
(Toronto is an example)
'suffering torn parts excessively' is the wordplay.
'suffering' is an anagram indicator.
'parts' means one lot of letters goes inside another (in the sense of cuts or separates).
'excessively' becomes 'too' (to too great a degree).
'torn' is an anagram of 'ront'.
'ront' going within 'too' is 'TORONTO'.
(Other definitions for toronto that I've seen before include "Canadian city" , "Capital city of Ontario" , "major city" , "Canada's largest city" , "Transatlantic city" .)
