Etymology
the word debunker is a distinctly 20th-century american formation. its core, "bunk," emerged as slang in the 1820s, a shortening of "buncombe," referring to meaningless political talk from buncombe county, north carolina. the latin prefix "de-" was added to signify the act of removing or reversing this nonsense. finally, the agent suffix "-er" was appended to denote the person performing this action. thus, the term literally means "one who removes nonsense," evolving from a specific political reference to a general label for someone who exposes falsehoods and myths.
