Harry sure loves US! (9)
I believe the answer is:
ourselves
'us' is the definition.
(us refers to ourselves)
'harry sure loves' is the wordplay.
'harry' indicates anagramming the letters (harry can mean to attack or spoil).
'sure'+'loves'='sureloves'
'sureloves' is an anagram of 'OURSELVES'.
(Other definitions for ourselves that I've seen before include "Us, reflexively" , "Emphatically us" , "See 16" , "We or us personally" .)
