Put into the hold (4)
I believe the answer is:
stow
'put into the hold' 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 "Deposit" , "Pack (object) away" , "Pack tightly" , "Pack or store carefully, luggage perhaps" , "Fill by packing tightly" .)
