Anyway, today's sweaty word is:
A juggler, trickster or deceiver. Originally used to describe a type of jester or juggler, tregetour, though now archaic, eventually came to mean someone who uses cunning tricks to deceive others (sometimes but not limited to stage performances).
From Old French tresgetour, from tresgeter, from Latin trans across and jetere to throw
I say the sewer thought I was dressed to bear a part in the tregetour’s mummery, and so I got admission — Walter Scott, Ivanhoe
