Easily snapped (7)
I believe the answer is:
brittle
'easily snapped' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for brittle that I've seen before include "Hard confectionery made with nuts" , "Hard but liable to break easily" , "apt to snap" , "Hard but easily broken" , "Easily cracked or snapped" .)
