Break down vs. Broke down – Which is Correct?
“Break down” and “broke down” are both correct, but they express different times. “Break down” is the base form, used for the present, future, commands, and after auxiliaries. “Broke down” is the simple past, used for a completed event. Choose based on when the action happened and context clues appear.
Break down or broke down – Which is Correct?
Break down and broke down are both correct forms of the irregular verb break down. The main difference is tense. Use break down for the base form, present-tense situations, commands, infinitives, and constructions with auxiliary verbs. Use broke down for a completed action in the past.
The phrasal verb break down has several meanings. A machine can stop working, a substance can be separated into smaller parts, a person can lose emotional control, or someone can analyze a complicated idea. In each case, broke down describes the same action after it happened.
The Best Trick to Remember the Difference
Use the time-marker test: if the sentence includes words such as yesterday, last night, earlier, or in 2025, choose broke down. If the action is happening now, may happen later, follows to, or follows an auxiliary such as will, can, or did, choose break down.
A useful swap test is this: replace the phrase with stop working or analyze. For example, “The printer broke down yesterday” describes a past event, while “The printer may break down tomorrow” describes a possible future event.
| Word | Part of Speech | Meaning | Example |
|---|---|---|---|
| break down | Phrasal verb; base form and present form | To stop functioning, separate, analyze, or lose emotional control | We need to break down the problem into smaller steps. |
| broke down | Phrasal verb; simple past | Stopped functioning, separated, analyzed, or lost emotional control in the past | The car broke down on the highway yesterday. |
