Na de les blijven we nog even kletsen in de gang.

Because Dutch main clauses follow the verb-second rule.

If you start the sentence with Na de les, that whole phrase takes the first position. The conjugated verb must then come second, so you get:

Na de les blijven we ...

If you start with the subject instead, then you get:

We blijven na de les ...

Both are correct. The first version puts a little more focus on after the lesson.

Na de les means after the lesson or after class.

The article de is used because les is being treated as a specific lesson/class period in the situation. Dutch often uses the article where English sometimes does too:

• na de les = after the lesson / after class

Here les can mean either the lesson itself or the class session, depending on context.

This structure means something like stay chatting, keep chatting, or continue chatting.

So blijven does not just mean physically to stay here. It combines with the infinitive kletsen to show that the action continues.

In this sentence, it suggests both ideas at once:

• they do not leave right away
• they continue chatting for a bit

Because after blijven, Dutch normally uses a bare infinitive.

So you say:

• blijven kletsen
• blijven praten
• blijven wachten

not:

• blijven te kletsen

This is one of those verb combinations you just learn as a pattern: blijven + infinitive.

Nog even is a very common Dutch expression. Here it means something like:

• for a little while
• a bit longer
• just for a moment

Word by word, it is not easy to translate naturally:

• nog can mean still, yet, or another
• even often softens the sentence and can suggest briefly or for a moment

Together, nog even gives the idea of doing something just a little longer or for a short time.

Not exactly.

Praten is the general, neutral word for to talk or to speak.

Kletsen is more like:

• to chat
• to chitchat
• to have a casual talk

So kletsen sounds more informal and relaxed. In this sentence, it suggests friendly, casual conversation rather than serious discussion.

That is a natural place for it in Dutch. It tells you where the chatting happens: in the hallway.

Dutch word order is quite flexible with phrases like this, especially with time and place phrases. This sentence sounds very normal:

Na de les blijven we nog even kletsen in de gang.

You could also hear:

Na de les blijven we nog even in de gang kletsen.

Both are possible. The version with in de gang at the end sounds very smooth and common.

Yes, absolutely.

That version is also correct and natural:

We blijven na de les nog even kletsen in de gang.

The difference is mainly emphasis and sentence flow:

• Na de les blijven we ... puts after the lesson first
• We blijven na de les ... starts more neutrally with the subject

It has a bit of both meanings here.

On its own, blijven often means to stay or to remain. But with an infinitive, it often works like keep or continue in English.

So in this sentence, the feeling is:

• they stay behind
• and they keep chatting

That is why a natural English translation may use either idea, depending on style.

Because we takes the plural verb form in the present tense.

The verb blijven is conjugated like this:

• ik blijf
• jij blijft
• hij/zij/u blijft
• wij/we blijven
• jullie blijven
• zij blijven

So we blijven is the correct form.

No. In Dutch, de gang here means the hallway or the corridor.

So:

• in de gang = in the hallway

It is a false friend for English speakers, because English gang usually means a group of people, but Dutch gang in this sentence has nothing to do with that meaning.
