Ich wohne nicht mehr in Berlin.

Nicht mehr means no longer or not anymore.

So Ich wohne nicht mehr in Berlin means that the speaker used to live in Berlin, but that is not true now.

This is different from plain nicht, which would just negate something without necessarily suggesting a change over time.

• Ich wohne nicht in Berlin. = I do not live in Berlin.
• Ich wohne nicht mehr in Berlin. = I do not live in Berlin anymore / no longer.

Because nicht mehr is a fixed expression in German meaning no longer / not anymore.

German often uses combinations like this as set phrases:

• nicht mehr = no longer
• noch nicht = not yet
• schon wieder = again already / yet again

So in this sentence, you should learn nicht mehr as one unit of meaning.

German main clauses usually follow the verb-second rule, often called V2.

In this sentence:

• Ich = position 1
• wohne = position 2
• nicht mehr in Berlin = the rest

That is normal German word order for a statement.

Even if something else comes first, the conjugated verb still stays in second position:

• In Berlin wohne ich nicht mehr.

Here, In Berlin is first, so wohne still has to be second.

Because wohne is the correct conjugated form for ich.

The infinitive is wohnen = to live / to reside.

Present tense:

• ich wohne
• du wohnst
• er/sie/es wohnt
• wir wohnen
• ihr wohnt
• sie/Sie wohnen

So Ich wohne means I live.

Both can often be translated as to live, but they are not always used in exactly the same way.

• wohnen usually focuses on where you live, meaning your place of residence.
• leben is broader and can mean to be alive, to live life, or also to live somewhere.

In this sentence, wohnen is especially natural because the sentence is about a location: in Berlin.

You could also say:

• Ich lebe nicht mehr in Berlin.

That is also correct, but wohnen sounds a bit more specifically about residence or home.

City names in German usually do not take an article.

So you say:

• in Berlin
• in London
• in München

Just like in English, you normally do not say in the Berlin.

Some place names do use an article, but they are exceptions, such as:

• die Schweiz
• die Türkei
• die USA

Then the article changes with the preposition:

• in der Schweiz
• in der Türkei
• in den USA

But with Berlin, there is no article: in Berlin.

Here, in takes the dative case because it expresses location, not movement.

A useful rule is:

• Wo? = where? → usually dative
• Wohin? = where to? → usually accusative with certain prepositions like in

Compare:

• Ich wohne in Berlin. = location → dative idea
• Ich ziehe in die Stadt. = movement into the city → accusative

With Berlin, you do not see a visible case ending because there is no article, but the underlying use is still the location use.

That sounds unnatural in a neutral statement.

The most natural version is:

• Ich wohne nicht mehr in Berlin.

In German, nicht mehr usually comes before the part it affects, and here it naturally affects the whole idea of living in Berlin now.

You might move things around for emphasis in special contexts, but for standard usage, Ich wohne nicht mehr in Berlin is the best choice.

In practice, nicht mehr negates the idea that the speaker still lives in Berlin now.

So the sentence does not mean that the speaker never lived there. It specifically means that the earlier situation has changed.

The important idea is:

• before: I lived in Berlin
• now: that is no longer true

That is why nicht mehr is so useful: it adds the sense of change over time.

Yes, very often it does.

Ich wohne nicht mehr in Berlin usually suggests:

• I used to live in Berlin
• I now live somewhere else, or at least I no longer live there

However, the sentence itself only clearly tells you one thing: Berlin is no longer my place of residence.

It does not explicitly say where the speaker lives now.

You can make it a yes/no question by putting the verb first:

• Wohnst du nicht mehr in Berlin? = Do you no longer live in Berlin?

Or an information question:

• Wo wohnst du jetzt? = Where do you live now?
• Seit wann wohnst du nicht mehr in Berlin? = Since when do you no longer live in Berlin?

This shows a common German pattern: in yes/no questions, the conjugated verb comes first.
