Ved fodgængerfeltet venter min datter, til lyset bliver grønt.

This is because Danish main clauses normally follow the V2 rule: the finite verb goes in the second position.

Here, Ved fodgængerfeltet is placed first, so the verb venter has to come next:

• Ved fodgængerfeltet venter min datter ...

If you start with the subject instead, the order changes:

• Min datter venter ved fodgængerfeltet ...

Both are correct. The first version gives a little more focus to the location.

Here ved means something like at, by, or near.

So ved fodgængerfeltet means at/by the pedestrian crossing.

Common uses of ved include location near something:

• ved døren = by the door
• ved stationen = by the station
• ved bordet = at the table

It does not mean physical contact in every case; it often just means being in that place or next to it.

Danish loves compound nouns, so several ideas are often joined into one word.

fodgængerfeltet can be broken down like this:

• fodgænger = pedestrian
• felt = field/marked area
• -et = the for a neuter singular noun

So:

• et fodgængerfelt = a pedestrian crossing
• fodgængerfeltet = the pedestrian crossing

Writing it as one word is completely normal in Danish.

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

For a neuter noun:

• et felt = a field/marking
• feltet = the field/marking

So:

• et fodgængerfelt = a pedestrian crossing
• fodgængerfeltet = the pedestrian crossing

This is different from English, where the is a separate word.

Because til lyset bliver grønt is a subordinate clause, and the sentence is written with a comma before it.

In Danish, this depends on the comma system being used:

• traditional comma: comma before subordinate clauses
• new comma: often no comma before subordinate clauses

So both of these may be accepted, depending on style:

• Ved fodgængerfeltet venter min datter, til lyset bliver grønt.
• Ved fodgængerfeltet venter min datter til lyset bliver grønt.

The version you were given uses the comma.

No. Here til is a conjunction meaning until.

It introduces the clause:

• til lyset bliver grønt = until the light turns green

So this is not the preposition to. Danish til can mean different things depending on context.

Compare:

• Jeg går til skolen = I go to the school
• Jeg venter, til bussen kommer = I wait until the bus comes

Same word, different function.

Because Danish uses different patterns for wait for and wait until.

• vente på + noun = wait for something/someone

  • Jeg venter på bussen. = I am waiting for the bus.

• vente til + clause/time = wait until

  • Jeg venter til i morgen. = I’m waiting until tomorrow.
  • Jeg venter til bussen kommer. = I wait until the bus comes.

In your sentence, the meaning is wait until the light turns green, so til is the right choice.

Because bliver shows a change: the light becomes/turns green.

• bliver grønt = turns green / becomes green
• er grønt = is green

In this sentence, the idea is that your daughter waits up to the moment when the light changes. That is why bliver is very natural.

If you said til lyset er grønt, that would focus more on the state of already being green. That can also make sense in some contexts, but bliver grønt emphasizes the transition.

Because lys is a neuter noun:

• et lys = a light

When an adjective is used with a neuter singular noun, it usually gets -t:

• et grønt lys = a green light

The same agreement appears after verbs like være and blive:

• Lyset er grønt = The light is green
• Lyset bliver grønt = The light turns green

Compare with a common-gender noun:

• en bil er grøn = a car is green

So the -t matches the neuter noun lyset.

Because Danish often uses the shorter word when the context already makes it clear what kind of light is meant.

Since the sentence mentions fodgængerfeltet, it is natural to understand lyset as the crossing light or traffic light.

So:

• lyset = the light/signal
• trafiklyset = the traffic light

Both can work, but lyset sounds natural when the situation is obvious.

Yes:

• Min datter venter ved fodgængerfeltet, til lyset bliver grønt.

That may feel more neutral to an English speaker, because English often starts with the subject.

The version with Ved fodgængerfeltet first is also perfectly normal. Danish often moves time or place expressions to the front for emphasis or flow. When that happens, the verb still stays in second position:

• Ved fodgængerfeltet venter min datter ...

So this is mainly a matter of word order and focus, not a change in basic meaning.
