Køen ved bageriet er lang om morgenen.

Køen is the definite form of kø, meaning the queue / the line.

• en kø = a queue / a line
• køen = the queue / the line

Danish often adds the definite article to the end of the noun instead of using a separate word like English the.

So:

• Køen ved bageriet = The line at the bakery

For the same reason as køen: bageriet is the definite form of bageri.

• et bageri = a bakery
• bageriet = the bakery

The noun bageri is a neuter noun in Danish, so its indefinite article is et, and its definite ending is -et.

Ved usually means by, at, or near. In this sentence, køen ved bageriet means the line at/by the bakery—probably outside it or associated with it.

If you said i bageriet, that would mean in the bakery, focusing more on being physically inside the bakery.

So:

• ved bageriet = at the bakery / by the bakery
• i bageriet = in the bakery

English often just says at the bakery, and Danish commonly uses ved in this kind of context.

This is standard Danish main-clause word order:

• Subject: Køen ved bageriet
• Verb: er
• Complement: lang

So it works like English:

• The line at the bakery is long

Danish usually puts the finite verb in second position in main clauses. Here, the subject comes first, so the verb naturally comes next.

Here, lang agrees with the noun kø, which is:

• common gender (en-word)
• singular
• indefinite in meaning as an adjective complement

After er, Danish often uses the basic adjective form in sentences like this:

• Køen er lang = The line is long

Compare:

• en lang kø = a long line
• køen er lang = the line is long
• lange køer = long lines

So lang is the correct singular form here.

Om morgenen is the normal Danish expression for in the morning or in the mornings, depending on context.

This is a fixed time expression:

• om morgenen = in the morning
• om aftenen = in the evening
• om natten = at night

Even though English does not use the here, Danish often uses the definite form in these expressions.

Om morgen exists in some contexts, but it is not the normal choice for this meaning in a standard sentence like this.

It can mean either, depending on context.

In a sentence like:

• Køen ved bageriet er lang om morgenen

it often has a general/habitual sense:

• The line at the bakery is long in the morning / in the mornings

So it may describe what is typically true in the morning rather than only one specific morning.

Not always. In Danish, lang can describe physical length, but it is also commonly used for things like a queue/line to mean long in the sense of many people or stretching far.

So:

• en lang vej = a long road
• en lang kø = a long line / queue

That is very natural in Danish, just as it is in English.

A rough guide is: KØ-en.

The difficult part is ø, a vowel that does not exist in standard English. It is somewhat similar to the vowel in French deux or German schön, but not exactly.

A few pronunciation notes:

• kø has one syllable
• køen is usually pronounced as two syllables: kø-en
• the ø sound should be rounded

English speakers often want to turn it into koo or ker-like sounds, but that is not correct.

A rough pronunciation guide is: ba-ge-ri-et, with four syllables.

Important points:

• the g in bageri is usually a soft Danish g, not a hard English g
• the ending -et in bageriet is the definite ending for a neuter noun

If you already know bageri, then bageriet is just that word plus the definite ending.

Danish often expresses the by adding an ending to the noun.

Examples:

• en kø = a line
• køen = the line
• et bageri = a bakery
• bageriet = the bakery

This is one of the biggest differences from English. Instead of writing the queue, Danish usually uses køen.

Yes. That is also a very natural sentence.

It means something like:

• There is a long line at the bakery in the morning

The difference is mainly focus:

• Køen ved bageriet er lang om morgenen focuses on the line
• Der er en lang kø ved bageriet om morgenen introduces the situation more like there is...

Both are good Danish.

Not always. Kø means queue/line in the sense of people waiting.

Examples:

• stå i kø = stand in line
• en lang kø = a long line

But English line has many meanings. For example, a drawn line on paper is not kø. So you should think of kø specifically as a queue or waiting line.

Yes:

• Om morgenen er køen ved bageriet lang.

That is perfectly correct. When a time expression comes first in a Danish main clause, the verb still stays in second position, so you get:

• Om morgenen
  • er
    • køen ved bageriet
      • lang

This is a very important Danish word-order rule.
