Put into someone's care (7)
I believe the answer is:
entrust
'put into someone's care' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for entrust that I've seen before include "Invest, commit" , "Put something into another's care" , "Charge (with) - put into the care (of)" , "Give custody of" , "Consign" .)
