Jeg går ikke i skole mere.

Yes, gå often means to walk, but it also has a wider meaning in Danish, similar to go in English.

In the expression gå i skole, it means to attend school or to be in school, not literally to walk to school.

So:

• Jeg går i skole = I go to school / I attend school
• Jeg går ikke i skole mere = I don’t go to school anymore

This is a fixed, very common expression.

Because gå i skole is the standard Danish expression for to go to school / attend school.

Even though English uses to, Danish uses i in this idiom. You should learn gå i skole as a whole phrase.

Compare:

• gå i skole = attend school
• gå på universitetet = attend university
• gå på arbejde = go to work

Prepositions often do not match English directly, so this is something to memorize as a set phrase.

In Danish, certain activities and institutions often appear without an article when you mean the general function of the place.

So i skole means at school / in school in a general sense, not in the school building as a specific place.

Compare:

• Jeg går i skole = I attend school / I’m in school
• Jeg går ind i skolen = I go into the school

The first is about your status or activity. The second is about a specific building.

In a normal main clause, Danish usually places ikke after the finite verb.

So:

• Jeg går ikke i skole mere

Structure:

• Jeg = subject
• går = finite verb
• ikke = not

This is standard Danish word order in main clauses.

You can compare:

• Jeg spiser ikke kød = I do not eat meat
• Han bor ikke her = He does not live here

Here, mere means anymore or no longer.

So ikke ... mere means not ... anymore.

Examples:

• Jeg bor ikke her mere = I don’t live here anymore
• Hun arbejder ikke her mere = She doesn’t work here anymore

Be careful: mere can also mean more in other contexts, but here, because it follows a negated statement, it means anymore.

Yes, very often you can.

• Jeg går ikke i skole mere
• Jeg går ikke i skole længere

Both can mean I don’t go to school anymore.

In many contexts, længere may sound a bit more formal or explicit, while mere is very common in everyday speech. In spoken Danish, ikke ... mere is extremely common.

Yes, går is the present tense of gå.

Danish often uses the present tense for things that are generally true now, including current habits or situations.

So Jeg går ikke i skole mere means that now it is true that you no longer attend school.

It is not about a single moment of movement. It is about your current situation.

Normally, no. The most natural interpretation is:

I no longer attend school.

That is, you have finished school or are not a student anymore.

If you wanted to talk about today or a specific trip, Danish would usually make that clearer, for example with time words or a different structure.

So by default, gå i skole is understood as attend school, not make a trip to school right now.

It is most natural at the end here:

• Jeg går ikke i skole mere

That is the usual placement.

You may sometimes hear different placement for emphasis in longer sentences, but for learners, the safest pattern is:

subject + verb + ikke + rest + mere

Examples:

• Jeg spiser ikke kød mere
• Han bor ikke i Aarhus mere

No, that would be incorrect.

In this sentence, mere belongs with the negation idea not anymore, so it should not go before ikke.

Correct:

• Jeg går ikke i skole mere

Think of ikke ... mere as working together to express no longer / not anymore.

In standard Danish, gå i skole is the normal expression.

So the expected sentence is:

• Jeg går ikke i skole mere

Using på skole would usually sound wrong or at least nonstandard in this meaning. For a learner, it is best to stick with gå i skole.

In a subordinate clause, ikke usually comes before the finite verb.

Main clause:

• Jeg går ikke i skole mere

Subordinate clause:

• Han siger, at jeg ikke går i skole mere
  = He says that I don’t go to school anymore.

So this is a useful contrast:

• Main clause: jeg går ikke
• Subordinate clause: jeg ikke går

It is completely normal, natural Danish. It works well in everyday speech and in writing.

If you want a slightly more formal variant, you might use længere:

• Jeg går ikke i skole længere

But Jeg går ikke i skole mere is very common and idiomatic.
