THE BASICS

Before we dive into the different idiomatic meanings of 'break down', it is always a good idea to look at the individual words which form it.


Firstly, we have the verb "to break", which is a common verb that has a few different meanings, however the main idea of the verb 'to break' means to stop something working, functioning or existing as it did before. This can be something physical such as a cell phone or a leg, or it can be something abstract such as a promise or an agreement.


We then have the prepositional particle 'down', which as an adverb means to be in a lower position or place ⬇️ and as a preposition means to move from a higher place to a lower place.


So, now we have that part out of the way, let's look at the different idiomatic meanings that we have when we combine these words to form our phrasal verb 'break down'.

 

MEANING 1: To stop working

To break

The first meaning of 'break down' that we will look at in this post is that which means to stop working or functioning. This is used specifically for machinery, equipment and vehicles.

Nouns commonly used with this application....

Car

Train / Bus / Airplane

Machine

Elevator / Lift

Vehicle

In my native speaker brain, this is the first meaning that I think of when I think about the phrasal verb 'break down'. This is probably because it is the most commonly used of all the meanings that we will look at in the post.


To be even more specific, you will hear people using this application most commonly in reference to cars that have developed a fault and stopped working. This is normally in the middle of a journey a long way from the person's home and so there is often an element of drama or at least a good story to be told. I was once riding a quad bike that broke down in the middle of the countryside on a Greek island and instead of spending the day relaxing on the beach as I had planned, I spent it trying to get the problem resolved and get back to the hotel 🤦🏻‍♂️....have you ever had any funny experiences breaking down somewhere? Let me know in the comments!


Of course, it is not just cars that break down and this usage can also be applied to any vehicles with an engine. Moreover, we use 'break down' to talk about machines that stop functioning too


Help! My car has broken down on the side of the freeway!

One more thing to note here is that the past particle form 'broken-down' is regularly used by native speakers as an adjective to describe a vehicle that is out of order.


There is a broken-down vehicle on the side of the road next to the bridge.
Engineers were called out to repair the broken-down train.

For this second meaning, imagine that you have a really big project that you are working on, which will involve a lot of time and effort. In order to work on this project in an efficient way, it is often a good strategy to separate it into smaller tasks, which you can then work on methodically, in order to complete the main project. Another way of describing this action is to break it down into smaller tasks and that is precisely what the second meaning of 'break down' is.

Nouns commonly used with this application....

  • Steps

  • Tasks

  • Segments

  • Parts

  • Chunks

If we put it another way, this application of 'break down' means to take something large or complex and make (or break) it into smaller parts, so that it can be dealt with or managed more easily and efficiently.


Typical usage of this second meaning of 'break down' is with complex questions, big projects and procedures, in other words things that contain many different parts and sections.


In addition, it is also possible to physically break something down into smaller pieces, e.g a cardboard box or some flatpack furniture.


Note that when using this meaning we require the additional preposition 'into' followed by the noun to describe the smaller parts that are the end result of the 'breaking down' process.


In order to effectively answer this complex question, we need to break it down into smaller subsections.
The process will be a lot smoother if you can break it down into small and manageable steps.

Our third meaning of 'break down' is very similar to the second meaning that we have just looked at and also means that something gets smaller. The difference here however is that in this meaning the pieces continue to get smaller and smaller until they disappear or stop existing.

Nouns commonly used with this application....

  • Chemical

  • Protein

  • Plastic

This meaning is normally one that you will hear in scientific language as it is used for things like chemicals, proteins and elements.


Another key difference between this third meaning and the second meaning is that there is no direct object here as nobody is making or causing the thing to break down - it happens naturally or at least without human intervention.


We can also use this to describe the sometimes unpleasant but totally natural process of decomposition or rotting that happens to all living things after they die.


Proteins breaks down into glucose in the body.
Plastic breaks down in the oceans, however it is an extremely long process.

For meaning number four of the phrasal verb 'break down', we are returning again to the core meaning of the verb 'to break', as well as the first meaning that we looked at. Like both of these, this fourth usage also means to stop functioning, but the difference here is that we are not talking about physical objects, but rather abstract ideas and concepts.

Nouns commonly used with this application....

  • Relationship / Marriage

  • Negotiations

  • Discussions / Talks

It is extremely common to use 'break down' in this way with abstract nouns such as relationships, discussions, and negotiations when they fail, are not successful or do not work out as originally planned.


Discussions between the two political parties broke down on the second day and abruptly ended.
Helen and John's marriage broke down when he found out that she had been carrying on with Lisa.

Potential synonyms

​To knock down, to remove, to demolish

Separable?

Yes

The next meaning that we are going to look at of the phrasal verb 'break down' is reserved especially for obstacles and barriers. If we have something that stands in our way and which we cannot get past, it is possible to use 'break down', to mean to demolish or reduce the barrier by using force, in order to remove it, thus clearing the way for us to continue.

Nouns commonly used with this application....

  • Door

  • Wall

  • Barricade / Barrier

  • Defenses

This is often used with physical nouns such as walls, barriers and doors, however it can also be used with abstract barriers such as barriers in society for people who are repressed in some way.

The firefighters had to break down the door to rescue the trapped residents.
The soldiers broke down the enemy’s defenses with heavy artillery.

MEANING 6: To start crying

Potential synonyms

To cry

Separable?

No

Our sixth and final meaning of 'break down' means to start crying or to become emotional.

This is something that we tend to use more for adults, rather than children, as I think it is used more to describe when a person loses control of their emotions due to a stressful or unpleasant experience in their life and it conveys a level of seriousness that we don't always associate with children crying.


We do not always use it for sad crying, however it can also equally be used for when we start crying because we are overcome with happy emotions.


This form of 'break down' is intransitive and does not have a direct object, so if you hear in a conversation that a person has broken down with no immediate object afterwards, you can be certain that the person is crying or emotional.


It is also common to hear the expression 'to break down in tears', however 'break down' on its own is fine to use.

John broke down in tears of joy when his son was born.

EXTRA TIPS TO SOUND MORE LIKE A NATIVE SPEAKER


You may remember that at the start of the post I mentioned that 'breakdown' is also commonly used as a noun in English.


When using it as a noun, we treat it as one word and the pronunciation is slightly different to when we use it in its phrasal verb form. When used as a noun, native speakers put slightly more stress on 'break' and less on 'down' than they do for the phrasal verb form, in which both parts have a similar level of word stress. See the video below to hear the pronunciation:



Used as a noun, breakdown is commonly used to talk about cars which have broken down, relationships or negotiations which have failed and you may also have heard of nervous breakdowns, which refer to when people become overwhelmed by stress in their lives. It should be noted that a nervous breakdown is not classed as an official medical term in English and may be referred to by health officials as a 'mental health crisis' instead.


Do you have adequate breakdown insurance cover for your car?
A breakdown in negotiations occurred as neither side was willing to change their mind and reach a compromise.
John is sending me a breakdown of all of the supplier costs from the last month.
