Updated: 2026-10-22

## Definition

to enter a place very quickly or to start doing something without thinking about it first.

For teachers: to enter a space with haste; figuratively, to commit to a course of action or decision without sufficient deliberation.

## Examples

- The children rush in when the school bell rings.
- You shouldn't rush in and sign the contract before reading the small print.
- The emergency responders had to rush in despite the structural instability of the burning warehouse to rescue the trapped occupants.

## Pitfalls

- Not "He rushed in the room." but "He rushed into the room." — Use 'into' to show movement toward the inside of a specific place; 'in' as a particle usually does not take a direct object in this sense.

## Usage notes

- often used as an intransitive verb to describe acting too quickly without a plan.
- Teaching tip: contrast with 'rush into', which requires an object; 'rush in' often stands alone to describe a general lack of caution.
