Prize for part of the hospital (5)
I believe the answer is:
award
'prize' is the definition.
(I know that prize can be written as award)
'for part of the hospital' is the wordplay.
'for' becomes 'a' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'part of the hospital' becomes 'ward' ('ward' is part of 'hospital').
'a'+'ward'='AWARD'
Can you help me to learn more?
(Other definitions for award that I've seen before include "Present - prize" , "Judicial decision" , "Perhaps Tony" , "Tony is one" , "Oscar, say" .)
