Buffoon, jester (4)
I believe the answer is:
fool
I believe this is a double definition.
'buffoon' is the first definition.
(I know that fool is a type of buffoon)
'jester' is the second definition.
(I know that jester can be written as fool)
(Other definitions for fool that I've seen before include "Part of 1 25 [KING LEAR]" , "Dupe - dessert" , "Jester or silly ass" , "Empty-headed person" , "Jester; dupe" .)
