Är du fri imorgon?

Because this is a yes/no question in Swedish. In main clauses, Swedish usually forms yes/no questions by putting the verb first.

• Statement: Du är fri imorgon. = You are free tomorrow.
• Question: Är du fri imorgon? = Are you free tomorrow?

So this is the normal verb + subject word order for a yes/no question.

Är is the present tense of vara, which means to be.

So:

• jag är = I am
• du är = you are
• han/hon är = he/she is

In this sentence, är means are.

Fri literally means free, but in this context it usually means free / available / not busy.

So Är du fri imorgon? is often asking whether someone is available tomorrow, not whether they are politically or personally free.

A very natural English translation is:

• Are you free tomorrow?
• Are you available tomorrow?

Yes, often you can. Ledig also means free, especially in the sense of not working, off, or available.

For example:

• Är du ledig imorgon? = Are you off / free tomorrow?

A rough difference is:

• fri = free in a broad sense
• ledig = free from work, school, duties, or occupied time

In everyday conversation, both can work, but ledig is very common when talking about schedule and availability.

In Swedish, imorgon is normally written as one word, and it means tomorrow.

You may also sometimes see i morgon, written as two words. That spelling exists too, but imorgon is very common in modern Swedish.

So for a learner, it is good to recognize both:

• imorgon
• i morgon

Both mean tomorrow.

Because Swedish, like English, usually does not need a preposition before words like today, tomorrow, and yesterday.

So you say:

• imorgon = tomorrow
• idag = today
• igår = yesterday

Not:

• på imorgon for this meaning

So Är du fri imorgon? follows the normal pattern.

A simple learner-friendly guide is:

• Är ≈ air
• du ≈ doo
• fri ≈ free
• imorgon ≈ ee-MOR-gon

A few pronunciation notes:

• ä in är is like the vowel in English air for many learners.
• r in Swedish varies by region, so do not worry if it does not sound exactly the same everywhere.
• fri is pronounced with a long i sound, like English free.
• In imorgon, the stress is usually on -mor-.

A rough full pronunciation could be:

• air doo free ee-MOR-gon?

Modern Swedish normally uses du with almost everyone. Unlike some languages, Swedish does not usually switch to a separate formal word for you in everyday speech.

So:

• du = you

This is correct with friends, coworkers, strangers, and most other people.

Older or very formal uses of Ni exist, but they are much less central than formal you forms in many other European languages. For most learners, du is the normal and correct choice.

Yes.

• Du är fri imorgon. = You are free tomorrow.
• Är du fri imorgon? = Are you free tomorrow?

The only major difference is the word order:

• statement: subject + verb
• yes/no question: verb + subject

Yes. That is also correct.

Both of these are acceptable:

• Är du fri imorgon?
• Är du fri i morgon?

The meaning is the same. The difference is just spelling style.

Imorgon is a time expression, and in a short sentence like this it often comes at the end:

• Är du fri imorgon?

But Swedish can move time expressions for emphasis:

• Är du imorgon fri? — possible, but less natural in most everyday situations
• Imorgon, är du fri? — possible if you want to emphasize tomorrow

For a learner, the safest and most natural pattern is:

• Är du fri imorgon?

Yes, very natural. It is a common way to ask whether someone is available tomorrow.

Depending on context, you might also hear:

• Är du ledig imorgon?
• Har du tid imorgon? = Do you have time tomorrow?
• Kan du imorgon? = Can you do tomorrow?

But Är du fri imorgon? is perfectly normal and idiomatic.
