Sikke et roligt kvarter du bor i!

Sikke is an exclamation word. In this sentence, Sikke et roligt kvarter ...! means something like:

• What a quiet neighborhood ...!
• Such a quiet neighborhood ...!

It is used to show surprise, admiration, or strong feeling.

A few similar examples:

• Sikke en dag! = What a day!
• Sikke et vejr! = What weather!
• Sikke nogle flotte huse! = What beautiful houses!

So sikke is not a normal question word here. It is an exclamative word.

Because kvarter is a neuter noun in Danish, so it takes et in the singular indefinite form:

• et kvarter

When an adjective comes before a neuter singular noun, the adjective usually gets -t:

• et roligt kvarter

Compare:

• en rolig gade = a quiet street
• et roligt kvarter = a quiet neighborhood

So both the article et and the adjective ending -t match the gender of kvarter.

This is adjective agreement.

The basic adjective is rolig = quiet/calm.

Before a singular neuter noun with et, you normally add -t:

• en rolig by = a quiet town
• et roligt kvarter = a quiet neighborhood

So roligt is just the neuter singular form of rolig.

Here kvarter means neighborhood, district, or area.

Danish kvarter can sometimes be confusing because it can also appear in time expressions, for example:

• et kvarter = a quarter of an hour / 15 minutes

But in et roligt kvarter, it clearly means a part of a town or city: a quiet neighborhood.

Because this is not a yes/no question.

The part du bor i means you live in and works like a clause describing kvarter:

• Sikke et roligt kvarter du bor i!
• literally: What a quiet neighborhood you live in!

This is very similar to English, where you also say:

• What a quiet neighborhood you live in!
• not What a quiet neighborhood do you live in!

So du bor i keeps normal statement order: subject + verb.

Because the verb phrase is bo i = live in.

So the full idea is:

• du bor i kvarteret = you live in the neighborhood

When kvarter is brought forward into the exclamation, the preposition i is left behind:

• Sikke et roligt kvarter du bor i!

This is called preposition stranding, and Danish does this quite naturally, just like English:

• the house I live in
• det hus jeg bor i

So the final i is completely normal here.

In normal Danish, that would sound unnatural here.

The most natural version is:

• Sikke et roligt kvarter du bor i!

You usually do not add som in this kind of exclamative structure.

A learner may expect a relative word because English sometimes feels like it has an implied relative clause, but Danish normally just says du bor i directly.

No, not usually.

• Sikke et roligt kvarter! is an exclamation: What a quiet neighborhood!
• Hvilket kvarter? is a question: Which neighborhood?

So sikke expresses emotion or reaction, while hvilket usually asks for information.

That is why Sikke et roligt kvarter du bor i! sounds natural, but Hvilket roligt kvarter du bor i! would not normally be used the same way.

Yes.

• Sikke et roligt kvarter! = What a quiet neighborhood!

That is a complete exclamation by itself.

Adding du bor i makes it more specific:

• Sikke et roligt kvarter du bor i! = What a quiet neighborhood you live in!

So the shorter version comments on the neighborhood in general, and the longer version connects it directly to the person you are speaking to.

Yes, it is natural spoken Danish.

It sounds like a spontaneous reaction when someone notices how peaceful an area is. The tone is usually admiring or surprised.

You might hear similar everyday sentences like:

• Sikke et flot hus du har! = What a beautiful house you have!
• Sikke en sød hund du har! = What a cute dog you have!
• Sikke et dejligt sted I bor! = What a lovely place you live!

So the pattern is very common and useful.

A rough learner-friendly pronunciation might be:

• SI-gə ed RO-li kvar-ter du bor i

A few helpful points:

• sikke has two syllables
• et is often said very lightly
• roligt is often pronounced more like ro-li in everyday speech, with the written g not strongly pronounced
• kvarter has stress on the last part: kvar-TER

Exact pronunciation varies a bit by speaker and region, but the important thing is to hear the sentence as a natural exclamation with strong stress on sikke and roligt or kvarter.
