Charge patients here? (4)
I believe the answer is:
ward
I believe this clue is a double definition.
'charge' is the first definition.
(both can mean a child in one's care)
'patients here?' is the second definition.
(I've seen this before)
(Other definitions for ward that I've seen before include "Minor with guardian - division of city" , "Local administrative district" , "Division of borough" , "number of patients" , "Minor in the charge of a guardian" .)
