Performer in car sets out (7)
I believe the answer is:
actress
'performer' is the definition.
(actress is a kind of performer)
'car sets out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'car'+'sets'='carsets'
'carsets' anagrammed gives 'ACTRESS'.
'in' acts as a link.
(Other definitions for actress that I've seen before include "Female player" , "one with a particular role?" , "Female in theatre" , "Recasts (anag) - performer" , "Female performer" .)
