Jeg tjekker indbakken, så snart jeg tænder computeren om morgenen.

Because tjekker is the present tense form of the verb at tjekke.

• at tjekke = to check
• jeg tjekker = I check / I am checking

In Danish, the present tense often covers both simple present and present progressive meanings in English, depending on context.

So:

• Jeg tjekker indbakken = I check the inbox / I’m checking the inbox

Here it describes a regular habit.

Because indbakken is the definite form: the inbox.

• en indbakke = an inbox
• indbakken = the inbox

Danish usually adds the definite article to the end of the noun instead of putting a separate word in front, as English does.

So:

• Jeg tjekker en indbakke would mean I check an inbox
• Jeg tjekker indbakken means I check the inbox

Så snart means as soon as.

It introduces a time clause:

• så snart jeg tænder computeren = as soon as I turn on the computer

It is a very common expression in Danish.

You can think of it as:

• så = so
• snart = soon

But together, så snart is a fixed expression meaning as soon as.

Because så snart jeg tænder computeren om morgenen is a subordinate clause, and Danish normally places a comma before subordinate clauses.

Main clause:

• Jeg tjekker indbakken

Subordinate clause:

• så snart jeg tænder computeren om morgenen

So the comma helps separate the two parts.

This is standard Danish punctuation.

Because the second part has its own subject and verb.

• Main clause: Jeg tjekker indbakken
• Subordinate clause: jeg tænder computeren

In English, you also say:

• I check the inbox as soon as I turn on the computer

You repeat I there too. Danish works the same way here.

Yes. At tænde often means to turn on / switch on.

Examples:

• tænde lyset = turn on the light
• tænde computeren = turn on the computer

For a computer, Danish speakers may also say things like starte computeren depending on context, but tænde computeren is completely natural and emphasizes powering it on.

Because the sentence refers to the computer in a general, familiar sense — probably the speaker’s own computer or the specific computer they use every morning.

• en computer = a computer
• computeren = the computer

So:

• jeg tænder computeren = I turn on the computer

This sounds more natural than a computer in this context.

Om morgenen means in the morning or in the mornings, depending on context.

Here it means something like in the morning / every morning as part of a routine.

Important difference:

• om morgenen = in the morning
• i morgen = tomorrow

So these are completely different expressions.

Also note:

• morgen = morning
• morgenen = the morning

In time expressions, Danish often uses om with parts of the day:

• om morgenen = in the morning
• om aftenen = in the evening

Because Danish, like English, often uses the present tense for habits and routine actions.

The sentence describes something the speaker usually does:

• Jeg tjekker indbakken = I check the inbox
• jeg tænder computeren om morgenen = I turn on the computer in the morning

So this is not about one specific morning only. It is about a regular pattern.

Yes, but the meaning changes slightly.

• så snart jeg tænder computeren = as soon as I turn on the computer
• når jeg tænder computeren = when I turn on the computer

Så snart emphasizes that the inbox is checked immediately after turning on the computer.

Når is more general and does not stress immediacy as strongly.

So both are possible, but så snart is more precise here.

The word order is normal Danish word order for a main clause followed by a subordinate clause.

Main clause:

• Jeg tjekker indbakken

Then subordinate clause:

• så snart jeg tænder computeren om morgenen

Inside the subordinate clause, the subject comes before the verb:

• jeg tænder

That is standard.

If you started the sentence with the time clause instead, the main clause would change word order because of Danish V2 word order:

• Så snart jeg tænder computeren om morgenen, tjekker jeg indbakken.

Notice that in this version it becomes tjekker jeg, not jeg tjekker.

Yes. At tjekke is a common Danish verb, borrowed from English check.

It is fully integrated into Danish grammar:

• at tjekke = infinitive
• tjekker = present tense
• tjekkede = past tense
• har tjekket = past participle/perfect construction

So even though it comes from English originally, it behaves like an ordinary Danish verb.
