Wij fietsen over het fietspad naar school, omdat de grote weg te druk is.

Both wij and we mean we.

• we is more common in everyday speech and writing.
• wij is a slightly fuller, more stressed form.

Dutch often uses wij when:

• the speaker wants a bit more emphasis,
• there is contrast,
• or in slightly more careful style.

So Wij fietsen ... is perfectly normal. In casual speech, many people would also say We fietsen ....

Here, fietsen is the verb to cycle / to ride a bike.

So:

• wij fietsen = we cycle / we are cycling / we go by bike

Dutch often uses the simple present where English might use either:

• we cycle to school
• we are cycling to school
• we go to school by bike

Also note that fietsen can also be the plural noun bicycles, but in this sentence it is clearly a verb because it comes right after the subject wij.

In this sentence, over het fietspad means something like via / along / on the bike path.

This can feel strange to English speakers, because English over usually suggests movement above something. Dutch over is broader and can be used for movement along a route or surface.

So:

• We fietsen over het fietspad = We cycle along/on the bike path

You may also hear op het fietspad:

• op het fietspad focuses more on being physically on the bike path,
• over het fietspad can sound a bit more like the route taken.

In real life, both can occur, depending on context and region.

Dutch nouns take either de or het.

• het fietspad is a het-word
• de weg is a de-word

Unfortunately, this is something you often have to learn with each noun.

A useful clue here is that fietspad is a compound:

• fiets = bicycle
• pad = path

The main word is the last part, pad, and pad is a het-word, so the whole compound is het fietspad.

Because Dutch adjectives usually take -e before a noun when the noun has a definite article like de or het.

So:

• de grote weg = the big road
• het grote huis = the big house

In this sentence:

• groot becomes grote because it comes before the definite noun weg

This -e ending is very common in Dutch adjectives before nouns.

naar means to / toward.

So:

• naar school = to school

There is no article here because Dutch often leaves out the article with places like school, huis, bed, kantoor, etc., especially when talking about the normal purpose of going there.

Compare:

• Ik ga naar school. = I go to school.
• Ik ga naar de school. = I am going to the school building (more specific)

So naar school is the natural general expression.

Because omdat introduces a subordinate clause.

Dutch normally separates a main clause and a subordinate clause with a comma, especially when the subordinate clause comes after the main clause.

So the sentence has two parts:

• main clause: Wij fietsen over het fietspad naar school
• subordinate clause: omdat de grote weg te druk is

The comma helps show that the second part gives the reason.

Because omdat is a subordinating conjunction, and in Dutch subordinate clauses, the finite verb usually goes to the end.

So:

• main clause: Wij fietsen ...
• subordinate clause: omdat de grote weg te druk is

That word order is very typical in Dutch:

• Ik blijf thuis, omdat ik moe ben.
• Zij komen niet, omdat ze geen tijd hebben.

English does not usually move the verb to the end in the same way, so this is something learners often need to get used to.

te before an adjective means too.

So:

• druk = busy / crowded
• te druk = too busy / too crowded

In this sentence, de grote weg te druk is means the big road is more busy or crowded than is acceptable or comfortable for the situation.

With roads, druk often means:

• busy with traffic
• crowded
• full of activity

Yes. In Dutch, druk is very commonly used for places, roads, shops, streets, and situations to mean:

• busy
• crowded
• full of traffic or people

So:

• een drukke straat = a busy street
• het is druk op de weg = the road is busy / there is a lot of traffic

That is very natural Dutch.

Yes, Dutch word order is somewhat flexible, but the verb usually stays in second position in a main clause.

The sentence as given is very natural:

• Wij fietsen over het fietspad naar school

You could also say things like:

• Naar school fietsen wij over het fietspad.
• Over het fietspad fietsen wij naar school.

These are grammatically possible, but they sound more marked because they emphasize the first element.

In normal everyday Dutch, the original order is the most neutral.

Not always literally, but it can work depending on context.

Word-for-word:

• de grote weg = the big road

But in context, it may refer to:

• the larger road,
• the main road,
• the major road.

A native Dutch speaker might also say:

• de hoofdweg = the main road

So de grote weg is understandable and natural if the speaker is contrasting a bigger road with a smaller bike path or local street. It emphasizes size or importance rather than giving the formal term.

A very natural spoken version might be:

• We fietsen over het fietspad naar school, omdat de grote weg te druk is.

The main difference is we instead of wij.

In fast speech, speakers may also reduce some sounds, but the grammar stays the same. The written sentence you have is already correct and natural.
