Absolute fury by hospital department (6)
I believe the answer is:
entire
'absolute' is the definition.
(thesaurus)
'fury by hospital department' is the wordplay.
'fury' becomes 'ire' (I've seen this before).
'by' says to put letters next to each other.
'hospital department' becomes 'ent'.
'ire' after 'ent' is 'ENTIRE'.
(Other definitions for entire that I've seen before include "porter" , "Unharmed - total" , "Complete, intact" , "in one piece" , "Utter" .)
