Celebrity in raptures, excited accepting ultimate in awards (9)
I believe the answer is:
superstar
'celebrity' is the definition.
(I know that superstar is a type of star)
'raptures excited accepting ultimate in awards' is the wordplay.
'excited' indicates anagramming the letters.
'accepting' is an insertion indicator (inserted letters are accepted).
'ultimate in' says to take the final letters.
The last letter of 'awards' is 's'.
'raptures' is an anagram of 'supertar'.
'supertar' placed around 's' is 'SUPERSTAR'.
'in' acts as a link.
(Other definitions for superstar that I've seen before include "Dazzling genius" , "Extremely famous performer" , "Big name" , "Dazzling virtuoso" , "Very famous person" .)
