Part's sure to be rewritten for celebrity (9)
I believe the answer is:
superstar
'celebrity' is the definition.
(thesaurus)
'part's sure to be rewritten' is the wordplay.
'to be rewritten' indicates anagramming the letters (I've seen 'being rewritten' mean this).
'parts'+'sure'='partssure'
'partssure' is an anagram of 'SUPERSTAR'.
'for' is the link.
(Other definitions for superstar that I've seen before include "Dazzling virtuoso" , "Very famous person" , "Dazzling genius" , "Extremely famous performer" , "Celeb" .)
