Break down

Stop working because of a fault, especially a vehicle or machine.

Examples you can use

How to use break down

In the machine-failure meaning, the machine is the subject: the car breaks down. No direct object is needed after down.

BASE FORMbreak down
PAST SIMPLEbroke down
AFTER HAVE / HASbroken down

The base form is used after can, will and to. The past simple describes a finished past event. The third form follows have or has, for example when connecting an earlier action to now.

A common mistake to avoid

Use thisThe car broke down yesterday.
Avoid this in this meaningThe car breaked down yesterday.

Break has the irregular past form broke and past participle broken.

Do not confuse it: Turn off means stop a device intentionally. Break down means stop because of a problem. A car that is simply parked with its engine off has not necessarily broken down.

Does it have another meaning?

Break something down can mean divide it into smaller parts. A person can also break down emotionally. Those are different meanings from a machine failing.

Learn the meaning and sentence pattern together. Small words such as up and off do not have one fixed meaning in every expression.
