Vi går over vejen ved lyskrydset.

In Danish, gå over is a very common way to say go across / cross when talking about moving on foot.

• går = go / walk (present tense of gå)
• over = over / across

So Vi går over vejen literally means We go across the road.

Danish also has the verb krydse = to cross, so Vi krydser vejen is also possible. But gå over vejen is very natural in everyday speech.

Vejen means the road or the street.

The base word is:

• vej = road / street

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

So:

• en vej = a road
• vejen = the road

The ending -en is the definite ending for many common-gender nouns.

Lyskrydset means the traffic-light intersection / the traffic lights junction.

It is a compound noun:

• lys = light
• kryds = crossing / intersection

Together, lyskryds means a road junction controlled by traffic lights.

Then Danish adds the definite ending:

• et lyskryds = a traffic-light intersection
• lyskrydset = the traffic-light intersection

So ved lyskrydset means something like at the traffic lights or at the traffic-light intersection.

Here ved means at / by / near.

So ved lyskrydset means at the traffic lights or by the intersection.

That is the natural preposition here because the sentence is locating where the crossing happens.

• ved lyskrydset = at the traffic lights
• i lyskrydset would mean in the intersection, which is a different idea and usually not what you want here

English also often uses at in this kind of sentence, so this is a helpful match.

Not always in a narrow, literal sense. Gå often means walk, but in many everyday expressions it is also just the normal verb for going on foot.

In this sentence, går over vejen suggests crossing the road as pedestrians.

So yes, walk is part of the idea, but the whole phrase is best understood as cross the road rather than focusing only on the physical act of walking.

Yes. That is correct Danish.

• Vi går over vejen ved lyskrydset = more everyday, literal We go across the road at the traffic lights
• Vi krydser vejen ved lyskrydset = We cross the road at the traffic lights

Both are natural, but gå over is especially common in everyday speech.

Because Danish usually puts the at the end of the noun.

Compare:

• en vej = a road

• vejen = the road

• et lyskryds = a traffic-light intersection
• lyskrydset = the traffic-light intersection

So English uses a separate article, but Danish often uses a suffix.

Yes. This is standard Danish main-clause word order:

• Vi = subject
• går = verb
• over vejen = expression of movement
• ved lyskrydset = place

So the sentence structure is very natural.

A useful thing to know is that Danish is a V2 language, which means the finite verb normally comes in the second position in main clauses. If you move ved lyskrydset to the front, the verb still stays second:

• Ved lyskrydset går vi over vejen.

That is also correct.

It can mean both, depending on context.

In many cases, vej is translated as either road or street in English. Danish does not always divide these ideas the same way English does.

So vejen here could be understood as:

• the road
• the street

The best translation depends on the situation.

A rough English-friendly approximation is:

vee gor oh-ver vigh-en vel LOOS-kry-set

But Danish pronunciation is tricky, so this is only approximate.

A few helpful points:

• Vi sounds roughly like vee
• går has a vowel sound English does not match perfectly
• vej sounds a bit like vigh
• ved often sounds softer than the spelling suggests
• lyskrydset is a compound, and the first part lys- is clearly heard

If you are learning pronunciation, it is best to listen to native audio, because Danish spelling and pronunciation often differ quite a lot.

Not exactly.

Ved lyskrydset means at the traffic lights / at the traffic-light intersection. It tells you the general location where the road is crossed.

It does not specifically name the pedestrian crossing itself. If you wanted to be more specific, Danish might use words like:

• fodgængerovergangen = the pedestrian crossing
• zebraovergangen = the zebra crossing

So the sentence means the crossing happens at the traffic lights, not necessarily that the speaker is naming the crossing markings themselves.
