Wij werken in januari.

Both wij and we mean we.

• we is usually the unstressed, more common form in everyday speech.
• wij is the stressed or more emphatic form, and it also appears in more careful or formal language.

So Wij werken in januari and We werken in januari both mean the same thing, but wij can sound a bit more explicit or emphasized.

The verb here is werken = to work.

In the present tense, Dutch verbs change depending on the subject:

• ik werk = I work
• jij werkt = you work
• hij/zij werkt = he/she works
• wij werken = we work
• jullie werken = you all work
• zij werken = they work

Because the subject is wij (we), the correct form is werken.

Werken is quite broad, like English to work.

It can mean:

• to have a job / do work
• to be functioning
• to be effective

In this sentence, with wij, it most naturally means we work or we are working.

Dutch uses in with months, just like English often does:

• in januari = in January
• in februari = in February

So in januari is the normal way to say something happens during that month.

It is in the present tense, but Dutch often uses the present tense for future meaning when the time is clear from context.

Because the sentence includes in januari, it can mean:

• We work in January
• We are working in January
• We will work in January

The exact English translation depends on context, but the Dutch sentence itself is perfectly natural.

This is a normal main clause in Dutch.

The basic word order is:

subject + verb + other information

So:

• Wij = subject
• werken = verb
• in januari = time expression

That gives: Wij werken in januari.

Dutch main clauses usually keep the finite verb in the second position, and this sentence follows that rule.

Yes. Dutch often allows the time phrase to come first.

You can also say:

In januari werken wij.

That version gives a bit more focus to in January. When something other than the subject comes first, the verb still stays in second position, so werken comes before wij.

No. In Dutch, names of months are normally written with a lowercase letter.

So:

• januari
• februari
• maart

This is different from English, where January is capitalized.

Wij is pronounced roughly like English why.

So:

• wij ≈ why

In normal speech, many speakers use we instead, which sounds shorter and more relaxed.

Yes, absolutely. That is very common and natural.

• Wij werken in januari = slightly more full or emphatic
• We werken in januari = very common everyday Dutch

Both are correct.
