Jeg bor ikke længere i den gamle lejlighed.

Bor is the present-tense form of bo, which means to live / reside somewhere.

So:

• jeg bor = I live
• du bor = you live
• han/hun bor = he/she lives

In Danish, present tense is often made by adding -r to the infinitive:

• bo → bor
• komme → kommer
• tale → taler

Here, bor is the natural verb because the sentence is about where someone lives.

Ikke længere means no longer or not anymore.

So:

• Jeg bor ikke længere ... = I no longer live ...
• literally: I live not longer ...

This is a very common Danish way to express that something used to be true, but is not true now.

Compare:

• Jeg bor i København. = I live in Copenhagen.
• Jeg bor ikke længere i København. = I no longer live in Copenhagen.

In a normal Danish main clause, the finite verb usually comes early, and sentence adverbs like ikke usually come after that verb.

So the pattern is often:

• subject + verb + ikke + other elements

In this sentence:

• Jeg = subject
• bor = finite verb
• ikke længere = negation/time expression

So:

• Jeg bor ikke længere i den gamle lejlighed.

This is standard Danish word order.

A learner might want to say something more English-like, such as placing ikke elsewhere, but Danish is stricter about this.

Yes, often you can, especially in everyday speech.

• ikke længere = no longer / not anymore
• ikke mere = not anymore / no more

So:

• Jeg bor ikke længere i den gamle lejlighed.
• Jeg bor ikke mere i den gamle lejlighed.

Both can work.

However:

• ikke længere is often the clearest and most standard choice for no longer
• ikke mere is more colloquial in many contexts

For a learner, ikke længere is a very safe and useful expression to remember.

Because in Danish, you normally live in an apartment, room, house, etc., so i is the natural preposition.

Examples:

• i en lejlighed = in an apartment
• i et hus = in a house
• i et værelse = in a room

So:

• Jeg bor i den gamle lejlighed. = I live in the old apartment.

Danish uses på with some locations, but not usually for being inside an apartment.

This means the old apartment.

It has three parts:

• den = the
• gamle = old
• lejlighed = apartment

A very important Danish pattern is:

• den/det/de + adjective + noun

when the noun is definite and has an adjective.

So:

• lejligheden = the apartment
• den gamle lejlighed = the old apartment

You use den because lejlighed is a common-gender noun (en lejlighed).

Because Danish adjectives change form depending on the grammar of the noun phrase.

The basic form is:

• gammel = old

But in a definite phrase with den/det/de, the adjective usually takes -e:

• en gammel lejlighed = an old apartment
• den gamle lejlighed = the old apartment

So:

• gammel is used in an indefinite singular common-gender phrase
• gamle is used here because the phrase is definite: den gamle lejlighed

This -e form is very common in Danish.

Because in Danish, when you have:

• den/det/de + adjective + noun

the noun usually stays in the indefinite-looking form, even though the whole phrase is definite.

So Danish says:

• den gamle lejlighed = the old apartment

not:

• den gamle lejligheden

Compare:

• lejligheden = the apartment
• den gamle lejlighed = the old apartment

This is a key difference from English and from some other Scandinavian languages, so it often feels strange at first.

Because lejlighed is an en-word (common gender noun):

• en lejlighed = an apartment

And for definite phrases with adjectives:

• en-word → den
• et-word → det

So:

• den gamle lejlighed = the old apartment
• det gamle hus = the old house

You usually have to learn the gender of each noun together with the noun itself.

Usually not freely.

Danish has a strong verb-second tendency in main clauses, and the placement of ikke is also fairly fixed.

Standard order here is:

• Jeg bor ikke længere i den gamle lejlighed.

If you move pieces around carelessly, the sentence can become ungrammatical or sound very unnatural.

For example, a learner might try something patterned on English word order, but Danish does not normally say it that way.

So this sentence is worth learning as a model:

• subject + verb + ikke længere + place

Not necessarily.

It simply means:

• the speaker used to live in that old apartment
• the speaker does not live there now

It does not tell you:

• why they left
• when they left
• whether the change is permanent
• whether they moved to another apartment, house, or city

So the sentence states a change, but not the full story.

Yes, but the meaning changes slightly.

• den gamle lejlighed = the old apartment
• min gamle lejlighed = my old apartment

The original sentence does not explicitly say my, even though English might sometimes naturally say it that way depending on context.

So:

• Jeg bor ikke længere i den gamle lejlighed. = I no longer live in the old apartment.
• Jeg bor ikke længere i min gamle lejlighed. = I no longer live in my old apartment.

Both are correct, but they are not exactly the same.

Yes, very much.

You can use this structure with many verbs:

• Jeg arbejder ikke længere her. = I no longer work here.
• Hun studerer ikke længere. = She no longer studies.
• Vi bor ikke længere i Aarhus. = We no longer live in Aarhus.

A very useful pattern is:

• [subject] + [verb] + ikke længere + ...

It is one of the best everyday ways to say no longer in Danish.
