הם רבו אתמול, אבל היום הם כבר השלימו ורוצים לשתות קפה ביחד.

Here it is pronounced ravu.

It is the past tense, 3rd person masculine plural form of לריב = to quarrel / to fight / to argue.

So:

• הוא רב = he argued
• הם רבו = they argued

A native English speaker may notice that רבו can be ambiguous in writing without vowels, but in this sentence the meaning is clearly they quarreled.

Not necessarily. In Hebrew, לריב is often used without stating the other side explicitly when it is obvious from context.

So הם רבו naturally means they had a fight / they argued.

If you want to make it explicit, you could say things like:

• הם רבו אחד עם השני = they argued with each other
• הם רבו זה עם זה = they argued with one another

But in your sentence, just הם רבו is completely normal.

כבר usually means already.

So:

• היום הם כבר השלימו = today they have already made up

It gives the sense that the conflict is over by now. It adds a feeling like:

• yesterday they were fighting,
• but today the situation has already changed.

Without כבר, the sentence would still make sense, but it would lose that extra nuance of already / by now.

In this sentence, השלימו means made up / reconciled.

It comes from the verb להשלים, which has several meanings depending on context, including:

• to complete
• to make peace
• to reconcile

Here, because the sentence first says הם רבו אתמול, the meaning is clearly:

• they reconciled
• they made up after a quarrel

Grammatically, השלימו is also past tense, 3rd person masculine plural.

Yes. That is very normal in Hebrew.

Examples:

• השלמתי את העבודה = I completed the work
• הם השלימו אחרי המריבה = they made up after the fight

The basic idea behind the verb is something like bringing to wholeness / restoring. From that, you get both:

• complete
• reconcile / make peace

Context tells you which meaning is intended.

Because the sentence moves from yesterday to today.

• הם רבו אתמול = they argued yesterday
• היום הם כבר השלימו = today they already made up
• ורוצים לשתות קפה ביחד = and they want to drink coffee together

So the timeline is:

1. past event: they argued
2. another completed event by today: they made up
3. present situation now: they want to drink coffee together

Using רוצים makes sense because it describes their current desire or intention.

Because Hebrew normally uses want + infinitive, just like English.

• רוצים = want
• לשתות = to drink

So:

• רוצים לשתות = want to drink

This is a very common Hebrew structure:

• אני רוצה לאכול = I want to eat
• הם רוצים ללכת = they want to go
• אנחנו רוצים ללמוד = we want to study

The ל־ at the beginning of לשתות is part of the infinitive form.

Literally, it means to drink coffee.

But in natural English, the best translation is often to have coffee together. Hebrew commonly says drink coffee where English might say have coffee.

So:

• רוצים לשתות קפה ביחד
  can be understood as
• they want to drink coffee together
• they want to have coffee together

Both capture the idea well.

Both mean together, and in many situations they are interchangeable.

• ביחד is very common in everyday spoken Hebrew
• יחד is also common and may sound a little shorter or slightly more neutral/formal depending on context

So this sentence could also say:

• ורוצים לשתות קפה יחד

That would still sound natural.

Yes, Hebrew could leave it out, but repeating it is very natural.

Your sentence says:

• הם רבו אתמול, אבל היום הם כבר השלימו...

The second הם helps clearly start the new clause after אבל.

You could also say:

• הם רבו אתמול, אבל היום כבר השלימו ורוצים לשתות קפה ביחד

That is also grammatical, especially when the subject is obvious. But repeating הם makes the sentence a bit clearer and more balanced.

They are masculine plural forms.

You can see that in:

• הם = they (masculine / mixed group)
• רבו = they argued
• השלימו = they made up
• רוצים = want (masculine plural)

Important note: In modern Hebrew, masculine plural is also used for mixed-gender groups.

If the group were all female, you would say:

• הן רבו אתמול, אבל היום הן כבר השלימו ורוצות לשתות קפה ביחד

The main change is:

• הם → הן
• רוצים → רוצות

Yes. Both are natural.

• הם רבו אתמול = they argued yesterday
• אתמול הם רבו = yesterday they argued

The difference is mostly one of focus:

• הם רבו אתמול starts with the subject
• אתמול הם רבו puts more emphasis on yesterday

Hebrew word order is fairly flexible, especially with time expressions like אתמול and היום.

It is basically neutral, everyday Hebrew.

Nothing in it sounds especially literary or especially slangy.

A few points:

• אבל = normal everyday but
• כבר = very common
• ביחד = common spoken-style word for together
• לשתות קפה = very natural everyday phrasing

So this is the kind of sentence a learner could comfortably use in normal conversation.
