Bowlingbanen er klar i bowlinghallen.

Because Danish, like English, often forms compound nouns by joining words together.

• bowling = bowling
• bane = lane, track, court
• bowlingbane = bowling lane

Then Danish adds the definite ending directly to the noun:

• en bowlingbane = a bowling lane
• bowlingbanen = the bowling lane

So bowlingbanen literally breaks down as bowling + bane + -en.

The ending -en is the usual definite article for many singular common-gender nouns in Danish. It corresponds to English the.

So:

• en bowlingbane = a bowling lane
• bowlingbanen = the bowling lane

and

• en bowlinghal = a bowling hall / bowling alley
• bowlinghallen = the bowling hall / the bowling alley

Unlike English, Danish often puts the at the end of the noun instead of using a separate word before it.

Because Danish usually expresses definiteness with a suffix attached to the noun.

In English:

• the bowling lane
• the bowling hall

In Danish:

• bowlingbanen
• bowlinghallen

So the sentence already includes the twice, but it is built into the nouns themselves.

They refer to two different things:

• bowlingbanen = the bowling lane
• bowlinghallen = the bowling hall / bowling alley / bowling center

So the sentence is talking about the lane being ready, and says that this lane is located in the bowling hall.

Er is the present tense of at være = to be.

So:

• er = is / are

In this sentence:

• Bowlingbanen er klar = The bowling lane is ready

It works just like English is.

Here klar means ready.

So:

• Bowlingbanen er klar = The bowling lane is ready

Depending on context, klar can also mean things like clear or finished/prepared, but ready is the most natural meaning in this sentence.

Because klar is agreeing with a singular common-gender noun: bowlingbanen.

Danish adjectives used after er can change form depending on gender and number:

• Bilen er klar = The car is ready
• Huset er klart = The house is ready
• Bilene/Bilerne er klare = The cars are ready

Since en bowlingbane is a common-gender noun, the correct form is klar.

I usually means in.

Here it marks location:

• i bowlinghallen = in the bowling hall

That makes sense because a bowling lane is physically located inside the bowling hall.

Normally, no. For this meaning, i bowlinghallen is the natural choice.

• i = in, inside
• på often means on, at, or on top of, and is used with certain places by convention

Since a bowling lane is inside the building, i bowlinghallen is the expected wording.

The sentence follows a very straightforward Danish pattern:

Subject + verb + complement + adverbial

• Bowlingbanen = subject
• er = verb
• klar = complement
• i bowlinghallen = adverbial of place

So literally:

• The bowling lane
  • is
    • ready
      • in the bowling hall

This is very similar to normal English word order.

Yes. Danish often uses loanwords, especially for modern activities, sports, and technology.

So bowling is borrowed, but the full word is still built in a Danish way:

• bowling + hal = bowling hall
• bowling + bane = bowling lane

This is very common in Danish compounds.

If you wanted to say A bowling lane is ready in a/the bowling hall, you would remove the definite endings where appropriate.

For example:

• En bowlingbane er klar i bowlinghallen.
  = A bowling lane is ready in the bowling hall.

Or:

• En bowlingbane er klar i en bowlinghal.
  = A bowling lane is ready in a bowling hall.

So the definite endings -en are what make the original sentence specific.

A learner should mainly notice two things:

1. It is one compound word.
2. The definite ending -en is an unstressed ending.

A rough learner-friendly pronunciation might be something like:

• bowlingbanen ≈ BOW-ling-bae-nen
• bowlinghallen ≈ BOW-ling-hal-en

The exact Danish vowels are different from English ones, but the main point is that the stress is earlier in the word, while the ending -en is lighter and less stressed.
