Jeg tjekker blot flynummeret.

Jeg is the subject form, meaning the person doing the action: I.

In Jeg tjekker blot flynummeret, jeg is the one checking, so Danish uses jeg.

Use mig when me would be used in English, for example:

• Han ser mig = He sees me
• Hun hjælper mig = She helps me

So:

• Jeg tjekker ... = I am checking ...
• not Mig tjekker ...

Tjekker is the present tense of at tjekke = to check.

So:

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

In Danish, the present tense often ends in -er:

• jeg arbejder = I work / I am working
• jeg kigger = I look / I am looking
• jeg tjekker = I check / I am checking

Notice that Danish usually uses the same present-tense form for both:

• I check
• I am checking

The context tells you which one is meant.

In a normal Danish main clause, the verb usually comes in second position. After that, short adverbs like blot often come before the object.

So:

• Jeg = subject
• tjekker = verb
• blot = adverb
• flynummeret = object

This gives:

• Jeg tjekker blot flynummeret.

That word order sounds natural in Danish.

English learners sometimes want to copy English word order too directly, but Danish often places adverbs like this neatly between the verb and the object.

Blot means just, simply, or merely.

In this sentence, it softens the statement:

• Jeg tjekker blot flynummeret = I’m just checking the flight number

Yes, blot is often very close to bare in meaning. In everyday spoken Danish, bare is usually more common:

• Jeg tjekker bare flynummeret

The difference is mostly one of style:

• bare = very common, neutral, everyday
• blot = a bit more formal, written, or careful in tone

So both are possible, but blot can sound slightly more polished.

Flynummeret means the flight number, while et flynummer means a flight number.

Danish often adds the definite article to the end of the noun instead of putting a separate word before it.

So:

• et flynummer = a flight number
• flynummeret = the flight number

This is one of the big differences from English. Instead of saying the flight number, Danish often builds the into the noun itself.

The ending -et makes the noun definite: the flight number.

The basic noun is:

• et flynummer = a flight number

The definite form is:

• flynummeret = the flight number

This happens because flynummer is a common neuter noun (an et-word). Many neuter nouns form the definite singular by adding -et:

• et hus → huset = the house
• et navn → navnet = the name
• et nummer → nummeret = the number

So:

• flynummer
  • -et = flynummeret

Yes. Danish very often combines nouns into one compound word.

Here:

• fly = flight / airplane-related
• nummer = number
• flynummer = flight number

English often writes these as separate words, but Danish commonly joins them:

• pasnummer = passport number
• telefonnummer = phone number
• flybillet = plane ticket / flight ticket

So it is completely normal that flynummer is written as one word.

Yes. Danish present tense often covers both meanings.

So:

• Jeg tjekker blot flynummeret

can mean:

• I just check the flight number
• I’m just checking the flight number

In real life, the second translation is often the more natural one in this context, but grammatically Danish uses the same verb form for both.

If you want to be more explicitly progressive in Danish, context usually does the job rather than a special verb form.

In normal pronunciation, jeg is often pronounced roughly like yai, yai/yei, or sometimes very reduced depending on accent and speed.

The final g is usually not pronounced like a hard English g.

So for learners:

• don’t say yeg
• think more like yai

Pronunciation varies across Denmark, but the important thing is that jeg does not sound the way it looks to an English speaker.

Yes, at tjekke comes from English check.

It has been adapted to Danish spelling and grammar:

• English: check
• Danish infinitive: tjekke
• present tense: tjekker

This is very common in modern Danish. Even though it comes from English, it behaves like a normal Danish verb.

You may also hear other verbs in similar situations where English has influenced modern Danish vocabulary.

It is possible in some contexts, but it is less neutral and less natural as a basic sentence.

The most natural version here is:

• Jeg tjekker blot flynummeret

Putting blot later can give it a slightly different emphasis or sound more marked:

• Jeg tjekker flynummeret blot

A learner should usually stick with:

• subject + verb + adverb + object

So Jeg tjekker blot flynummeret is the safest and most idiomatic choice here.
