‘Shyster’ may possibly be the funniest word in the English language. Check this shit out and be prepared to tear up laughing:

“A shyster is someone who acts in a disreputable, unethical or unscrupulous way, especially in the practice of law and politics, or is a con artist. Shyster is a slang word and calling someone a shyster could be considered libellous“

The word is derived from the German verb scheissen, “to defecate” and the English suffix -ster, “one who does”. Shyster is an alteration of the German scheißer, which literally means “defecator” or an “incompetent worthless person”.

There is no basis to conclude that a possible origin includes Shylock, a character in Shakespeare’s The Merchant of Venice and the owner of a stall or shy in a market place.
