Possibly save for trip or break (4,5)
I believe the answer is:
fall apart
'break' is the definition.
(synonyms)
'possibly save for trip' is the wordplay.
I cannot really see how this works, but
'trip' could be 'fall' (trip can mean to fall over) and 'fall' is located in the answer.
The remaining letters 'apart' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'or' is the link.
Can you help me to learn more?
(Other definitions for fall apart that I've seen before include "Disintegrate" , "Go to pieces" , "Come to pieces" .)
