CEFR B1 · Phrasal verb

Source: https://englishreference.com/word/break-in
Updated: 2026-10-22

## Definition

to enter a building by force, usually to steal something.

For teachers: to enter a premises by force or without permission, typically with criminal intent. Often used intransitively when the location is implied.

## Examples

- Someone tried to break in while we were away.
- The burglars managed to break in through a small window in the back of the house.
- Security footage revealed that the suspects attempted to break in multiple times before finally bypassing the electronic lock.

## Pitfalls

- Not "The thief broke in the office." but "The thief broke into the office." — Use 'break in' alone; if you name the place, you must use 'break into'.

## Usage notes

- This form is intransitive; if you want to mention the building, use 'break into' instead.
- Teaching tip: Help students distinguish between the intransitive 'break in' and the transitive 'break into' to avoid common preposition errors.
