Ace part of hospital getting prize (5)
I believe the answer is:
award
'prize' is the definition.
(I know that prize can be written as award)
'ace part of hospital getting' is the wordplay.
'ace' becomes 'a' (abbreviation).
'part of hospital' becomes 'ward' (hospitals have wards).
'getting' says to put letters next to each other.
'a'+'ward'='AWARD'
(Other definitions for award that I've seen before include "Endow" , "E.g. Oscar" , "Grant - prize" , "Oscar, say" , "Perhaps Tony" .)
