Wrong hospital wing (4)

Ross

I believe the answer is:

harm

'wrong' is the definition.
(thesaurus)

'hospital wing' is the wordplay.
'hospital' becomes 'h'.
'wing' becomes 'arm' (both can mean a side).
'h'+'arm'='HARM'

(Other definitions for harm that I've seen before include "Hurt, maim" , "Hurt, injure" , "Injure, injury" , "Injure or damage" , "Damage, hurt" .)

I've seen this clue in The Telegraph.
