Where you'd hope to recover charge (4)
I believe the answer is:
ward
I believe this is a double definition.
'where you'd hope to recover' is the first definition.
(someone might recover in a hospital ward)
'charge' is the second definition.
(I've seen this before)
(Other definitions for ward that I've seen before include "Separate room" , "zone for votes" , "custody" , "One under the protection of another" , "Hospital room; part of borough" .)
