Benefactor giving disorganised hospital PR hint (14)
I believe the answer is:
philanthropist
'benefactor' is the definition.
(philanthropist is a kind of benefactor)
'disorganised hospital pr hint' is the wordplay.
'disorganised' indicates anagramming the letters.
'hospital'+'pr'+'hint'='hospitalprhint'
'hospitalprhint' is an anagram of 'PHILANTHROPIST'.
'giving' acts as a link.
(Other definitions for philanthropist that I've seen before include "Benefactor" , "Carnegie, say" , "he's good to us" , "Giver to good causes" .)
