Har du med dig din mobil?

Because this is a yes/no question in Swedish.

In a normal statement, you would usually say:

Du har med dig din mobil.
= You have your phone with you.

But in a yes/no question, Swedish normally puts the verb first:

Har du med dig din mobil?
= Do you have your phone with you?

So this is very similar to English using Do you have... ?, even though Swedish does not need a separate helping verb like do here.

Med dig literally means with you.

• med = with
• dig = you (object form)

So the phrase ha med sig / ha med dig / ha med mig means to have something with you / bring something along / be carrying something.

In this sentence, Har du med dig din mobil? means not just Do you own a phone?, but specifically Do you have your phone with you right now?

Because Swedish needs both parts to express with you:

• med = with
• dig = you

You cannot just say Har du med din mobil? if you mean Do you have your phone with you? That would sound incomplete or wrong in standard Swedish.

The structure is:

ha med sig något = have something with you

When speaking to someone directly, sig changes depending on the person:

• Jag har med mig min mobil = I have my phone with me
• Har du med dig din mobil? = Do you have your phone with you?
• Hon har med sig sin mobil = She has her phone with her

Because din means your, and the person being spoken to is du.

• din = your
• sin = his/her/their own, referring back to the subject of a third-person sentence

So:

Har du med dig din mobil?
is correct because you are talking directly to you.

You would use sin in a sentence like:

Hon har med sig sin mobil.
= She has her phone with her.

Here, sin refers back to hon.

A useful rule:

• use min / din / vår / er for I / you / we / you
• use sin / sitt / sina when the subject is he, she, it, they and the thing belongs to that same subject

Because mobil is a common gender noun in Swedish, not a neuter noun.

Swedish has two main genders for nouns:

• en-words → take din
• ett-words → take ditt

Since it is:

en mobil

you say:

din mobil

Compare:

• din mobil = your phone
• ditt hus = your house

So the possessive must match the gender of the noun.

Yes. In everyday Swedish, mobil very commonly means mobile phone / cell phone.

You may also hear:

• mobiltelefon = mobile phone

But mobil is extremely common and natural in speech.

So din mobil is a normal way to say your phone.

Yes, absolutely. That is also natural Swedish.

Both of these are possible:

• Har du med dig din mobil?
• Har du din mobil med dig?

They mean essentially the same thing: Do you have your phone with you?

The version with med dig earlier in the sentence is very common because ha med sig works almost like a set phrase.

So for a learner, it is useful to remember:

ha med sig något = have something with you / bring something along

Here har is the present tense of ha = to have.

But in this sentence, it is not just simple possession in the abstract. It means something closer to:

• have with you
• be carrying
• have on you
• have brought along

So:

Har du en mobil?
= Do you have a phone? / Do you own a phone? or Do you have a phone available?

But:

Har du med dig din mobil?
= Do you have your phone with you?

That extra idea comes from med dig.

Common answers would be:

• Ja. = Yes.
• Ja, det har jag. = Yes, I do.
• Ja, jag har med mig den. = Yes, I have it with me.
• Nej. = No.
• Nej, det har jag inte. = No, I don’t.
• Nej, jag glömde den hemma. = No, I forgot it at home.

In everyday conversation, short answers like Ja or Nej are very common.

In careful pronunciation, dig is traditionally something like dej in modern spoken Swedish.

In everyday speech, learners will often hear:

• med dig sounding roughly like me dej

So even though it is spelled dig, the pronunciation often does not sound like English dig.

This is useful because beginners sometimes hear Har du me dej din mobil? and do not realize it is the same as Har du med dig din mobil?
