Wij hoeven geen taxi te nemen, want het station is vlak bij.

Yes. Wij and we both mean we.

• we is the unstressed, everyday form
• wij is the stressed or more emphatic form

So all of these are possible:

• Wij hoeven geen taxi te nemen.
• We hoeven geen taxi te nemen.

In normal spoken Dutch, we is very common. Wij can sound a bit more deliberate, contrastive, or slightly more formal.

Here, hoeven means to need or to have to, but it is usually used in negative sentences, questions, or other contexts with limitation.

So:

• Wij hoeven geen taxi te nemen = We don’t need to take a taxi

A very important point for English speakers:

• hoeven is often used where English uses need to
• but in Dutch it naturally appears with negation very often

Compare:

• Ik hoef niet te gaan = I don’t need to go
• Hoef ik te wachten? = Do I need to wait?

Without negation, Dutch often prefers moeten instead, depending on the meaning.

Because Dutch normally uses geen to negate an indefinite noun.

So:

• een taxi = a taxi
• geen taxi = no taxi / not a taxi

In this sentence, taxi is an indefinite singular noun, so geen is the natural choice.

Compare:

• Ik heb een fiets. = I have a bike.
• Ik heb geen fiets. = I don’t have a bike.

Use niet for other kinds of negation, for example with adjectives, adverbs, verbs, definite nouns, and whole clauses.

Because hoeven is followed by te + infinitive.

So the pattern is:

• hoeven te + infinitive

Examples:

• Ik hoef niet te werken = I don’t need to work
• We hoeven niet te wachten = We don’t need to wait
• Wij hoeven geen taxi te nemen = We don’t need to take a taxi

This is different from the true modal verbs such as kunnen, moeten, mogen, which usually take a bare infinitive without te:

• Ik kan komen
• Ik moet gaan

So hoeven behaves differently here.

Because Dutch main clauses usually place the finite verb in the second position, and the other verb forms tend to go toward the end.

In this sentence:

• Wij = subject
• hoeven = finite verb, so it comes in second position
• geen taxi = object
• te nemen = infinitive phrase at the end

So the structure is roughly:

• Wij | hoeven | geen taxi | te nemen

This is a very common Dutch word-order pattern.

This is a very important distinction.

• Wij hoeven geen taxi te nemen = We don’t need to take a taxi
• Wij moeten geen taxi nemen usually means something more like We must not take a taxi or We shouldn’t take a taxi

So:

• niet hoeven = not need to
• niet moeten = must not / should not

English speakers often mix these up because English uses must, have to, and need to in ways that do not map perfectly onto Dutch.

Both can often translate as because, but they behave differently in word order.

With want, the next clause keeps normal main-clause word order:

• ..., want het station is vlak bij.

With omdat, the clause becomes subordinate, so the verb goes to the end:

• ..., omdat het station vlak bij is.

Both are possible here. The difference is mainly grammatical structure, though style and rhythm can differ too.

Vlak bij means very close, nearby, or close by.

In this sentence:

• het station is vlak bij = the station is very close / nearby

The word vlak adds the idea of very or right here, so it is stronger than just bij.

You can think of it as something like:

• close
• really near
• right nearby

Because station is a het-word in Dutch.

Dutch nouns take either:

• de
• or het

So:

• het station
• het huis
• de auto
• de taxi

Unfortunately, this is something you often have to learn with each noun. There are patterns, but many nouns simply have to be memorized.

Geen replaces een completely.

So:

• een taxi = a taxi
• geen taxi = no taxi / not a taxi

You do not say:

• geen een taxi ❌

That would be wrong in this sentence.

So the correct phrase is simply:

• geen taxi

Yes. Een taxi nemen literally means to take a taxi, just like in English.

This is a normal Dutch expression:

• de bus nemen = take the bus
• de trein nemen = take the train
• een taxi nemen = take a taxi

So this part works very similarly in both languages.

Yes, but it means something slightly different.

• Wij hoeven geen taxi te nemen = We don’t need to take a taxi
  This means no taxi is necessary at all.

• Wij hoeven de taxi niet te nemen = We don’t need to take the taxi
  This refers to a specific taxi or a previously mentioned taxi.

So the difference is:

• geen taxi = no taxi, indefinite
• de taxi = the taxi, definite/specific

Because Dutch usually does not negate indefinite nouns that way.

If the meaning is not any taxi / no taxi, Dutch prefers geen:

• Wij hoeven geen taxi te nemen

Using niet een taxi would sound unusual here and would often suggest contrast, as if you meant:

• not one taxi, but something else

So in ordinary Dutch, geen taxi is the correct and natural form.
