Star skier sat out (8)
I believe the answer is:
asterisk
'star' is the definition.
('asterisk' can be a synonym of 'star')
'skier sat out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'skier'+'sat'='skiersat'
'skiersat' is an anagram of 'ASTERISK'.
(Other definitions for asterisk that I've seen before include "Star-shaped character used in printing" , "Footnote marker" , "Star-shaped mark in printing" , "Star for the printer" , "Printer's star" .)
