## Definition

the most silly or not smart. You use this to describe the person or thing with the lowest intelligence in a group.

For teachers: the superlative form of 'stupid'; describes the person, action, or idea possessing the least amount of intelligence or common sense in a given set.

## Examples

- That was the stupidest mistake I have ever made.
- The team lost the game because of the stupidest error in the final seconds of play.
- Historians often debate which policy was the stupidest, but most agree that this particular law caused the most avoidable damage to the local economy.

## Pitfalls

- Not "the most stupidest" but "the stupidest" — Double superlatives are incorrect; 'stupidest' already includes the 'most' meaning.

## Usage notes

- Superlative adjective; typically preceded by the definite article 'the'.
