1. He was breaking down/up under the strain. Can both down and up be used? Any differences?

2. Sentences can be broken up into clauses. (taken from OXFORD)
Each lesson is broken down into several units. (taken from OXFORD)

It seems to me that 'break down' here equals 'break up' in these sentences. How can we decide when to use one and when to use the other?

Thank you in advance.

To "break down" under stress is not the same as to break something into pieces.

"break up" can be used to mean the relationship is coming to an end, causing the people to separate.

"break up" can also mean to burst into laughter.

I don’t see how “break down” and “break up” could mean the same thing, though “break down into” and “break up into” are synonymous.

For your first sentence, only “break down” works.
Simply, “break down” :”break up” could be analogized by "temporary": "permanent".

I think in your first sentence only "break down" is correct.

You are talking about different meanings of "break up" and "break down" which makes answering your question difficult.

About your second and third sentences:
"break up into" and "break down into" are similar to each other. I am tempted to say they are synonyms.

OXFORD: break up
5 (British English) to become very weakHe was breaking up under the strain.

From the sentence above came my question. Could anyone further clarify my puzzle? Thank you all again.

:shock:

I now have a mental picture of this man breaking up under the strain - arms, legs and head all going their separate ways... :lol:

I would have said he was breaking down, connecting this with the expression 'to have a nervous/mental/physical breakdown'. But if this is what a dictionary has told you, I'd better not argue. :roll:

A car breaks down when the engine fails, but breaks up when it hits a wall at 100 mph.

I would break a sentence down into its component parts, but would break up a large rock in order to be able to move it.

If I found two children fighting I would tell them to break it up, (or maybe I'd just watch...) and when two boxers in the ring start hugging each other, the referee also tells them to break up.

At the end of its life, a car goes to the breaker's yard to be broken up and a ship to the shipbreaker's for the same operation.

This is quite interesting! I've not thought about it before, but it seems that henz988 may have come up with a valid theory - temporary vs permanent. It does seem to work, but I'm sure there will be exceptions.

It's those awkward prepositions again, isn't it? They do make life so difficult, but we couldn't manage without the little darlings. You just have to learn their strange habits as you go along.

I left London when my marriage broke down.

break up:
5 if a marriage, group of people, or relationship breaks up, the people in it separate and do not live or work together any more:

He lost his job and his marriage broke up.

Can we say that 'my marriage broke down' roughly equals 'my marriage broke up' in the above contexts? Or is the 'up' closest to 'completely' in meaning?
Thank you again.

Roughly, yes. For me, and I stress that this is a personal view, 'break up' has more of a suggestion that the two people actually split up and, at some time, divorced.

The main problem is that the two phrasal verbs can be near-synonyms in certain contexts and not in others. While dictionaries attempt to present generally accepted usage, they cannot possibly cover every example.

Personal opinion creeps in. For example:

henz988: I don’t see how “break down” and “break up” could mean the same thing,
Sorry henz, but I feel that they could, in certain contexts.

henz988: For your first sentence, only “break down” works.
I disagree. I think 'break down' is what I would expect to see, but 'break up' is not impossible.

henz988:Simply, “break down” :”break up” could be analogized by "temporary": "permanent".
Perhaps, sometimes. I feel that it would be unsafe to take this as a general rule,

Hi, fivejedion.
What is the possibility here that “the strain” could get a person’s limbs separated (a picture mentally formed in my mind)? Maybe I misunderstood “break up”? Could you please spare a few more minutes on “not impossible” and give some examples? I know you mean extreme occasions, however, as an ESL, I am always interested in these things.

Thank you.

I don't have any problem with a person "breaking up under the strain". I agree that it's not as common as "breaking down" but I have heard it said, and after all it is suggesting the same sort of mental disintegration.

As fivejedjon says, yes - roughly. But I think the Longman definitions are clear and correct here (better than your earlier one). Whilst 'break up' in this context indicates the finality of the separation (divorce), 'break down' emphasizes the process of gradual deterioration in the marriage. A marginal difference, but worth noting.

That's what an ESL wants, at least it makes me comfortable. I don't know why.:-D

Thanks.

If by that you mean that you want a clear answer, remember that a clear answer may not be the only answer - it may not even be the right answer! My own opinion is very similar to Dude's, but I think we would have to analyse a lot of authentic examples before we could state categorically that this was the correct and only interpretation of these two expressions in the context of the ending of a marriage.

Note that I began my previous answer with "For me, and I stress that this is a personal view....".

Yes, I totally agree with you.
That said, I feel it dreadful for an ESL. It seems that an ESL could never learn to be an idiomatic speaker without immersing in the target language for quite a long while. We always need some “simplified rules” to guide us on a commoner ground, and that, on the other hand, will always single us out as a nonnative speaker.:-D

Don't worry about being easily identified as a non-native English speaker. Whilst you naturally want to be as fluent as possible, you are right to realise that perfect fluency would only come after a long stay in an English-speaking country.

Personally, I am always delighted to meet a non-native speaker - I see someone who's making the effort to learn my language and I feel this is an honour. My French is not good, but whenever I'm in France, speaking poor French without embarrassment, I find that people are especially attentive and helpful. They don't see it as a problem, so neither do I.
