Where you might put your holiday items to be safe (2,4)
I believe the answer is:
in case
'where' is the definition.
Both the definition and answer are adverbs. Perhaps they are linked in a way I don't understand?
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for in case that I've seen before include "In order to allow for eventualities" , "Packed" , "Where traveller may keep clothes" , "As a precaution" , "for emergency" .)
