När jag får bekräftelsen, känner jag mig mycket lugnare.

När means when. It introduces a time clause: När jag får bekräftelsen = When I get the confirmation.

In Swedish, clauses starting with när are very common for talking about something that happens at a certain time. Here it tells you when the main action happens: I feel much calmer when I get the confirmation.

Swedish very often uses the present tense to talk about the future when the time is clear from the context.

So När jag får bekräftelsen literally looks like When I get the confirmation, but it can refer to a future event just fine.

This is very natural in Swedish:

• När jag kommer hem, ringer jag dig. = When I get home, I’ll call you.
• När hon är klar, går vi. = When she’s finished, we’ll go.

You do not need a special future form here.

The comma separates the introductory time clause from the main clause:

• När jag får bekräftelsen = subordinate clause
• känner jag mig mycket lugnare = main clause

In Swedish, people often use a comma here, especially in careful writing, but it is not always strictly necessary in modern informal writing. The important thing for a learner is really the word order that follows the opening clause.

This is because Swedish follows the V2 rule in main clauses: the finite verb must come in the second position.

When the sentence begins with the subordinate clause När jag får bekräftelsen, that whole clause takes the first position. So in the main clause, the verb must come next:

• När jag får bekräftelsen, känner jag mig mycket lugnare.

Not:

• När jag får bekräftelsen, jag känner mig mycket lugnare.

This is one of the most important Swedish word-order patterns to learn.

Literally, it is feel I myself.

The verb is känna sig, which means to feel in the sense of being in a certain emotional or physical state.

So:

• Jag känner mig lugn. = I feel calm.
• Hon känner sig trött. = She feels tired.

The mig is necessary because Swedish uses this reflexive structure with many feeling/state expressions.

Because the subject is jag, and the reflexive pronoun that matches jag is mig.

The reflexive forms are:

• jag → mig
• du → dig
• han/hon/man → sig
• vi → oss
• ni → er
• de → sig

So:

• Jag känner mig lugn.
• Du känner dig lugn.
• Vi känner oss lugna.

Bekräftelsen is the definite form, meaning the confirmation.

Swedish often attaches the definite article to the end of the noun:

• en bekräftelse = a confirmation
• bekräftelsen = the confirmation

So the speaker is referring to a specific confirmation, not just any confirmation.

Here får means get or receive.

The infinitive is få, which can mean several things depending on context, such as:

• get / receive
• may / be allowed to
• sometimes must / have to in certain expressions

In this sentence, the meaning is clearly receive:

• När jag får bekräftelsen = When I receive the confirmation

Lugnare is the comparative form of lugn:

• lugn = calm
• lugnare = calmer

Mycket lugnare means much calmer.

So the sentence is comparing two states:

• before getting the confirmation
• after getting the confirmation

The speaker is not just calm, but calmer than before.

In Swedish, many adjectives form the comparative by adding -are:

• lugn → lugnare
• snabb → snabbare
• billig → billigare

So:

• Jag är lugn. = I am calm.
• Jag känner mig lugnare. = I feel calmer.

And if you want to strengthen it, you can add mycket:

• mycket lugnare = much calmer

With a comparative adjective like lugnare, Swedish normally uses mycket for much:

• mycket lugnare = much calmer
• mycket bättre = much better

Väldigt usually means very, and it works best with the basic adjective, not the comparative:

• väldigt lugn = very calm
• mycket lugnare = much calmer

So mycket is the natural choice here.

Yes, a very important one.

• när = when, for something expected or seen as a real event
• om = if, for something uncertain or conditional

So:

• När jag får bekräftelsen... = When I get the confirmation...
  This suggests the speaker expects it to happen.
• Om jag får bekräftelsen... = If I get the confirmation...
  This suggests uncertainty.

In your sentence, när shows that the speaker assumes the confirmation will come.

Because each clause needs its own subject.

The sentence has two clauses:

1. När jag får bekräftelsen
2. känner jag mig mycket lugnare

The first jag belongs to the first clause. The second jag belongs to the main clause.

English also does this:

• When I get the confirmation, I feel much calmer.

So the repetition is completely normal.

Yes. You can put the main clause first:

• Jag känner mig mycket lugnare när jag får bekräftelsen.

This means the same thing. The difference is mostly emphasis and sentence flow.

Notice the word order change:

• After the opening time clause: känner jag mig
• If the main clause comes first: jag känner mig

That is the V2 rule again.

A rough pronunciation guide is:

beh-KREF-tel-sen

A few notes:

• ä sounds somewhat like the vowel in English bed, though not exactly the same.
• The stress falls on kräft.
• The -elsen ending is pronounced fairly lightly.

If you learn it in parts, it is easier:

• be
• kräft
• elsen

So: be-KRÄFT-el-sen.
