## Definition

to make something simpler so more people can understand it, but in a way that makes it less intelligent.

For teachers: to simplify material to make it accessible to a broader audience, typically with the negative connotation of reducing intellectual quality or complexity. The verb is transitive and frequently appears in the passive voice.

## Examples

- The TV show dumbs down the science to make it easier to follow.
- The textbook was criticized for dumbing down the historical facts to the point of being inaccurate.
- The editorial argued that the current political discourse has been significantly dumbed down by the relentless pursuit of soundbites over substantive policy debate.

## Pitfalls

- Not "The author had to dumb down it for the public." but "The author had to dumb it down for the public." — when the object is a pronoun, it must be placed between the verb and the particle.

## Usage notes

- This phrase usually carries a negative tone, suggesting that the simplification is unnecessary or insulting to the audience.
- Teaching tip: Contrast with 'simplify' to show how 'dumb down' implies a loss of quality; it is a common term in discussions about media and education.
