White-faced clown (7)
I believe the answer is:
pierrot
'white-faced clown' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for pierrot that I've seen before include "Clown from French panto - tripe or what" , "he's white-faced at work" , "In French panto, clown with white face and baggy costume" , "Period; incantation" , "Sad white-faced clown" .)
