Metroen er hurtigere end bussen.

Here end means than.

It is the standard word Danish uses in comparisons:

• hurtigere end = faster than
• større end = bigger than
• bedre end = better than

So even though end looks like the English word end, it does not mean that here.

Because Danish usually adds the definite article to the end of the noun.

• en metro = a metro
• metroen = the metro
• en bus = a bus
• bussen = the bus

So the sentence is talking about the metro and the bus, not just a metro and a bus.

That is a spelling pattern in Danish.

With some nouns, when an ending is added, the final consonant is doubled in writing. This often helps show that the vowel before it stays short.

• bus → bussen
• kat → katten

But metro already ends in a vowel, so it just becomes metroen.

So this is mainly a spelling issue, not a change in meaning.

Hurtigere is the comparative form of hurtig.

• hurtig = fast
• hurtigere = faster
• hurtigst = fastest

For many short adjectives in Danish, you make the comparative by adding -ere.

Normally, no. In standard Danish, hurtigere is the natural form.

Danish often uses:

• -ere for many short, common adjectives
• mere with longer adjectives or adjectives that do not normally take -ere

For example:

• hurtig → hurtigere
• interessant → mere interessant

So in this sentence, hurtigere is the correct and normal choice.

Er is the present tense of at være, which means to be.

So:

• Metroen er hurtigere ... = The metro is faster ...

The sentence is describing a state or quality, so Danish uses er just like English uses is.

No. Danish verbs do not change by person in the present tense the way English does.

You say:

• jeg er = I am
• du er = you are
• metroen er = the metro is
• vi er = we are

So er stays the same.

This is the normal word order for a main statement:

• subject + verb + complement

So:

• Metroen = subject
• er = verb
• hurtigere end bussen = the rest of the comparison

Danish also follows the verb-second rule in main clauses. That means the finite verb usually comes in the second position.

For example:

• Metroen er hurtigere end bussen.
• Om morgenen er metroen hurtigere end bussen.

In both sentences, er stays in second position.

In the comparative, Danish adjectives usually stay the same form regardless of gender, number, or definiteness.

So you can say:

• Metroen er hurtigere
• Toget er hurtigere
• Busserne er hurtigere

Unlike basic adjective forms such as hurtig / hurtigt, the comparative hurtigere does not normally change.

Yes, slightly.

• Metroen er hurtigere end bussen = The metro is faster than the bus
  This sounds like you mean specific, known things.

• En metro er hurtigere end en bus = A metro is faster than a bus
  This sounds more general, like a general statement about metros and buses.

So the choice between definite and indefinite changes how specific the sentence sounds.

A rough guide is:

• Metroen: stress the tro part
• er: usually very short and unstressed
• hurtigere: often said quickly, with the middle sounds reduced in everyday speech
• end: the d is often very weak or not clearly heard
• bussen: ends with a soft unstressed -en

A useful thing to know is that spoken Danish is often more reduced than the spelling suggests, so learners may not hear every written sound clearly at first.
