Root Explanation

Debunk is formed from the prefix "de-" (meaning down or away) and the root "bunk" (from the slang term meaning nonsense or falsehood). The word originally means to take down or expose something as false or nonsensical.

Memory Tip

Think of 'taking down' ('de-') something that is 'nonsense' ('bunk') — that's why debunk means to expose falsehoods.
