Stash away (4)
I believe the answer is:
stow
'stash away' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for stow that I've seen before include "Pack (in proper place)" , "Pack tightly" , "- - -on-the-Wold" , "Pack or store carefully, luggage perhaps" , "Store away tidily" .)
