## Definition

to show that a popular belief or idea is actually false. You use this when you prove that a story or theory is not true.

For teachers: to expose the falseness or hollowness of a myth, idea, or belief. Often used in the context of scientific or journalistic investigation to disprove widely held misconceptions.

## Examples

- The scientist wrote a book to debunk common myths about diet.
- After the video went viral, several experts came forward to debunk the claims that it showed a real ghost.
- While the documentary attempted to debunk the long-standing conspiracy theory, it inadvertently provided a platform for further speculation among those already inclined to distrust official narratives.

## Synonyms

disprove, expose, refute, invalidate, discredit

## Antonyms

confirm, prove, validate, verify

## Pitfalls

- Not "He debunked about the theory." but "He debunked the theory." — Debunk is a transitive verb and does not take the preposition 'about'.

## Usage notes

- The verb is transitive and requires a direct object, typically an abstract noun like 'myth', 'theory', or 'claim'.
