Puts away almost entire storehouse with emergency assistance (7)
I believe the answer is:
deposes
'away almost entire storehouse with emergency assistance' is the definition.
I can't judge whether this definition defines the answer.
'puts' is the wordplay.
I cannot really understand how this works, but
'puts' could be 'poses' ('pose' can be a synonym of 'put') and 'poses' is present in the answer.
The remaining letters 'de' 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 deposes that I've seen before include "Removes from office" , "Gives testimony" .)
