Mix up stuff bishop left in storage on vacation (8)
I believe the answer is:
scramble
'mix up' is the definition.
(I've seen this in another clue)
'stuff bishop left in storage on vacation' is the wordplay.
I cannot quite see how this works, but
'stuff' could be 'cram' (synonyms) and 'cram' is located in the answer.
'bishop' could be 'b' (chess abbreviation) and 'b' is found within the answer.
'left' could be 'l' (common abbreviation) and 'l' is present in the answer.
The remaining letters 'se' 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).
Can you help me to learn more?
(Other definitions for scramble that I've seen before include "Get along somehow" , "Stir eggs vigorously" , "motorcycle trial" , "Climb awkwardly -- move quickly" , "difficult climb" .)
