Its rate is adjusted for a professional performer (7)
I believe the answer is:
artiste
'a professional performer' is the definition.
(I've seen this before)
'its rate is adjusted' is the wordplay.
'is adjusted' indicates anagramming the letters.
'its'+'rate'='itsrate'
'itsrate' with letters rearranged gives 'ARTISTE'.
'for' is the link.
(Other definitions for artiste that I've seen before include "Player" , "Tears it (anag.)" , "professional dancer?" , "Attires like entertainer" , "A sitter for a performer" .)
