A chain found in Italy (9)
I believe the answer is:
apennines
'in italy' is the definition.
('Apennines' is part of 'italy')
'a chain' is the wordplay.
'chain' becomes 'pennines' (I have seen 'chain of hills' mean 'pennines' so perhaps 'chain' could also mean 'pennines').
'a'+'pennines'='APENNINES'
'found' acts as a link.
(Other definitions for apennines that I've seen before include "Great mountain range in Italy (9)" , "Mountain range in central Italy" , "Italian mountain chain" , "Italian mountain range" , "European range" .)
