Ik sta op om voor het werk koffie te drinken.

Because opstaan is a separable verb.

• The full infinitive is opstaan = to get up
• In a main clause, the conjugated verb goes to the usual verb position, and the separable prefix moves to the end.

So:

• Ik sta op = I get up
• not Ik opsta

This is a very common Dutch pattern:

• ik bel je op = I call you up
• hij doet de deur open = he opens the door

But in the infinitive, the parts stay together:

• opstaan
• op te staan

This structure expresses purpose: in order to ...

So om ... te drinken means something like:

• to drink
• in order to drink

In this sentence, Ik sta op om ... koffie te drinken means that the reason for getting up is to drink coffee.

This is a very common Dutch pattern:

• Ik ga naar de winkel om brood te kopen.
• Zij belt om hulp te vragen.

So the pattern is:

• om + ... + te + infinitive

After om in a purpose clause, Dutch normally uses te + infinitive.

So you get:

• om koffie te drinken
• om brood te kopen
• om Nederlands te leren

You cannot normally say:

• om koffie drinken

That would sound incomplete or wrong here.

A useful rule:

• om ... te + infinitive = to / in order to + verb

Because the part after om is an infinitive clause, and Dutch usually puts the infinitive verb at the end of that clause.

So the structure is:

• Ik sta op
• om voor het werk koffie te drinken

Inside that second part, drinken comes last.

This is very normal Dutch word order:

• om een boek te lezen
• om met vrienden te praten
• om morgen vroeg te vertrekken

English often puts the verb earlier, so this can feel unusual at first.

Here, voor het werk most naturally means before work.

So it tells you when the coffee is being drunk.

A learner should know that voor can have different meanings depending on context, such as:

• before
• for
• in front of

In this sentence, the time meaning is the important one.

So voor het werk koffie te drinken means drinking coffee before starting work.

Dutch often uses the article with werk in expressions like this.

So voor het werk is a normal way to say before work.

If you remove the article, the meaning usually changes or sounds less natural in this exact sentence.

Compare:

• voor het werk = before work
• voor werk = for work, because of work, related to work

So in your sentence, het helps make werk refer to the general daily activity or work period.

No. It is the same word in spelling, but it has a different function.

There are at least two very common uses of om:

• om acht uur = at eight o’clock
• om koffie te drinken = to drink coffee, in order to drink coffee

In your sentence, om introduces a purpose clause, not a time expression.

So here it means something like in order to.

Yes. Dutch often gives you two options:

1. om ... te + infinitive
2. a full clause with its own subject and finite verb

For example, a fuller version could be:

• Ik sta op zodat ik voor het werk koffie kan drinken.
• Ik sta op voordat ik ga werken om koffie te drinken.

The om ... te version is very compact and common when the subject is the same as in the main clause.

Here, the person who gets up and the person who drinks coffee is the same person: ik.

That is exactly the kind of situation where om ... te works well.

Usually, yes.

Opstaan most often means to get up in the sense of getting up from bed or getting up to start the day.

So Ik sta op normally suggests:

• I get out of bed
• I get up in the morning

In some contexts, opstaan can also just mean physically standing up, but in a sentence like this, the everyday meaning is very likely getting up from bed.

Because koffie is the object of drinken, and in Dutch infinitive clauses, the object usually comes before the final verb.

So:

• koffie te drinken
• een boek te lezen
• de auto te verkopen

This is a standard pattern:

• object first
• infinitive verb last

That is why koffie appears before drinken.
