noun — [moun-tuh-bangk]

definition: a person who deceives others, especially in order to trick them out of their money; a person who sells quack medicines, as from a platform in public places, attracting and influencing an audience by tricks, storytelling, etc.

history: Italian montambanco, a contraction from the phrase monta im banco, meaning “one gets up onto the bench” (so as to attract attention to sell things).

Quack refers to any fraudulent practitioner of medicine or law. Mountebank may imply some quackery, but more often it refers to a self-promoting person who resorts to cheap tricks or undignified efforts to win attention.

example usage:

The United States is only a nation, and we are experiencing no temptations except those that are common to man. And there is a way of escape. Stop voting for mountebanks.
