Reach Apennines, for example (5)
I believe the answer is:
range
I believe this is a double definition.
'reach' is the first definition.
(synonyms)
'apennines for example' is the second definition.
(apennines is a kind of range)
(Other definitions for range that I've seen before include "Cooking appliance" , "testing ground" , "Grassland - variety" , "spectrum" , "Mountain stretch" .)
