Hand over for safekeeping (7)
I believe the answer is:
entrust
'hand over for safekeeping' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for entrust that I've seen before include "Give for safekeeping" , "Give custody of" , "Assign (a responsibility to someone)" , "Place in someone's 22 ac" , "Place in the care or protection of someone" .)
