Flugtvejen går til brandtrappen.

Because Danish makes very heavy use of compound nouns.

• flugtvej = flugt
  • vej
• brandtrappe = brand
  • trappe

English often writes similar ideas as two words, like escape route or fire escape, but Danish usually joins them into one word.

This is very normal in Danish, so long nouns are common.

Those endings are the definite article in Danish, so they mean the.

• flugtvej = escape route

• flugtvejen = the escape route

• brandtrappe = fire escape / fire staircase
• brandtrappen = the fire escape / the fire staircase

So instead of putting a separate word like the in front, Danish usually adds the definite article to the end of the noun.

Both are definite singular, but the noun shape affects the ending.

• flugtvej becomes flugtvejen
• brandtrappe becomes brandtrappen

A very common pattern is:

• nouns ending in a consonant often take -en
• nouns ending in an unstressed -e often take just -n

So trappe → trappen is completely regular.

That is a very common learner question.

Here, går does not mean that the escape route is physically walking. Danish, like English, often uses a verb of movement in a broader sense.

In this kind of sentence, går can mean something like:

• goes to
• leads to
• runs to
• extends to

So for paths, roads, stairs, corridors, routes, and similar things, gå is often used even though nothing is moving.

Til means to, and here it marks the destination or endpoint.

So:

• går til brandtrappen = goes/leads to the fire escape

This is the natural preposition when you want to show where something leads.

Yes. This is a very standard Danish main clause:

• Flugtvejen = subject
• går = finite verb
• til brandtrappen = prepositional phrase

So the structure is:

Subject + Verb + complement

It also matches the Danish verb-second pattern: in a main clause, the finite verb normally comes in the second position. Since the subject is first here, the verb comes right after it.

Yes. fører til is also natural and may sound a bit more explicit as leads to.

So these are both possible:

• Flugtvejen går til brandtrappen
• Flugtvejen fører til brandtrappen

The version with går til is idiomatic and common when talking about where a route, corridor, or staircase goes.

Both flugtvej and brandtrappe are common gender nouns, so they are en-words:

• en flugtvej
• en brandtrappe

That is why their definite singular forms are built with -en or -n, not -et.

If they were neuter (et) nouns, the definite singular would use -et instead.

The most useful thing to know is the stress pattern:

• FLUGT-vejen
• BRAND-trappen

In Danish compounds, the stress is usually strongest on the first part of the word.

A rough guide for an English speaker:

• vej sounds roughly like v-eye
• trappe is roughly trap-uh, but the final vowel is weak

Danish pronunciation is often more reduced than spelling suggests, so even if you do not get every sound perfectly, getting the main stress right will help a lot.
