Vi måste stötta varandra.

Vi means we. It is the subject pronoun used when the speaker includes themselves together with one or more other people.

Examples:

• Vi kommer snart. = We are coming soon.
• Vi måste gå. = We must go.

In Vi måste stötta varandra, vi is the group that has the obligation to do something.

Måste means must or have to.

It comes from the verb måste / måste in modern usage, but in practice learners usually treat måste as a modal verb, like English must. Modal verbs are used together with another verb in the basic form.

So in:

• Vi måste stötta varandra

the structure is:

• vi = we
• måste = must
• stötta = support

Just like English We must support each other.

Because Swedish modal verbs normally take the next verb without att.

So you say:

• Jag kan simma. = I can swim.
• Du vill äta. = You want to eat.
• Vi måste stötta varandra. = We must support each other.

Not:

• Vi måste att stötta varandra.

This is similar to English, where we say must support, not must to support.

Stötta is the infinitive form of the verb, like English to support.

After måste, Swedish uses the infinitive without att:

• måste stötta
• kan hjälpa
• vill gå

So stötta is not a tense form by itself here; it is the verb that follows the modal verb måste.

Stötta usually means support, especially in a personal, practical, or emotional sense.

In many contexts, stötta sounds like:

• encouraging someone
• helping someone
• being there for someone

It can sometimes be physical in a literal sense, but in a sentence like Vi måste stötta varandra, it usually means we need to help/support one another emotionally, socially, or practically.

They are very close in meaning, but they are not used in exactly the same way.

• stötta often sounds a bit more personal, everyday, and direct
• stödja can sound a bit more formal or broader

Examples:

• Vi måste stötta varandra. = We need to support each other.
  This sounds natural in everyday speech.
• Organisationen stödjer forskning. = The organization supports research.
  Here stödjer is often more natural.

In many situations, both can work, but stötta varandra is a very common and natural phrase.

Varandra means each other or one another.

It is used when two or more people do something mutually.

Examples:

• De älskar varandra. = They love each other.
• Vi hjälper varandra. = We help each other.
• Vi måste stötta varandra. = We must support each other.

So varandra shows that the action goes both ways within the group.

Because varandra expresses a mutual action, while oss själva means ourselves.

Compare:

• Vi måste stötta varandra. = We must support each other.
  The people in the group support one another.
• Vi måste stötta oss själva. = We must support ourselves.
  This focuses on the group helping itself, not necessarily person-to-person mutual support.

So varandra is the natural choice when the meaning is reciprocal.

It can be used for both two people and larger groups.

Examples:

• Anna och Erik hjälper varandra. = Anna and Erik help each other.
• Vi i laget stöttar varandra. = We on the team support each other.

So in Vi måste stötta varandra, the group could be two people or many people.

Yes, Swedish word order can change depending on emphasis or sentence structure, but the basic order here is:

subject + modal verb + main verb + object

So:

• Vi måste stötta varandra.

This is the most neutral and natural form.

You can move something else to the front in other sentences, but then Swedish usually uses V2 word order, meaning the verb stays in the second position.

For example:

• Nu måste vi stötta varandra. = Now we must support each other.

Here nu comes first, so måste still stays in second position.

A rough pronunciation is:

• måste ≈ MOS-teh, but with a Swedish å sound

A few details:

• å is not like English a; it is more like the vowel in British English thought for many speakers
• the e at the end is pronounced, not silent

So it is closer to MO-steh than to anything like mast.

These are important Swedish vowels:

• å in måste: a rounded vowel, often somewhat like the vowel in thought
• ö in stötta: a front rounded vowel that English does not really have

A rough help:

• stötta may sound a bit like sturta or sterta to English ears, but neither is exact

The best approach is to listen to native audio and imitate, because English does not have perfect matches for these sounds.

Yes. That would mean We need to support each other.

The difference is roughly:

• Vi måste stötta varandra = We must support each other / We have to support each other
  Stronger, more urgent, more necessary
• Vi behöver stötta varandra = We need to support each other
  Slightly softer in tone, though still important

Both are natural, but måste sounds stronger.

The sentence is in the present tense form because måste is the finite verb in the sentence.

But in meaning, it expresses necessity rather than a simple present action.

So:

• Vi måste stötta varandra does not mainly mean we are supporting each other now
• it means it is necessary for us to support each other

If you want past meaning, you could say:

• Vi måste stötta varandra can sometimes still refer to a present or general necessity
• Vi var tvungna att stötta varandra = We had to support each other

Yes, very natural.

Vi måste stötta varandra is a common kind of phrase in everyday speech, especially when talking about:

• family
• friends
• teamwork
• difficult situations
• solidarity

It sounds natural, idiomatic, and emotionally supportive.
