Fright wig wearer (5)
I believe the answer is:
clown
'fright wig wearer' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for clown that I've seen before include "Behave playfully" , "Chap fooling around" , "Joker" , "Comic entertainer; fool" , "Jester" .)
