Hospital for men? (4)
I believe the answer is:
guys
This clue is a double definition.
'hospital' is the first definition.
(I've seen this before)
'men?' is the second definition.
'for' acts as a link.
(Other definitions for guys that I've seen before include "Ridicules by comic imitation" , "Ridicules American men?" , "Tent ropes; people" , "Makes fun of < hospital" , "Nowadays people of either sex" .)
