Jeg vil rydde op i køkkenet, før gæsterne kommer.

Vil means want to or sometimes will, depending on context. In this sentence, Jeg vil rydde op means I want to tidy up.

• Jeg rydder op = I am tidying up / I tidy up
• Jeg vil rydde op = I want to tidy up

So vil adds the idea of intention or desire, not just the action itself.

Rydde op is a very common Danish expression meaning to tidy up, clean up, or put things in order.

It is a fixed verb expression:

• at rydde op = to tidy up

The word op is part of the expression, so you usually need it. Without op, rydde on its own can mean something more like clear away or remove, depending on context.

In Danish, some verbs work like phrasal verbs in English and can split in a main clause.

So:

• infinitive: at rydde op
• present tense: jeg rydder op
• with another verb like vil: jeg vil rydde op

This is normal Danish word order. The verb phrase is still one unit in meaning, even though it may look split.

I køkkenet means in the kitchen.

• i = in
• køkkenet = the kitchen

So the phrase tells you where the tidying up will happen.

Køkkenet is the definite form, meaning the kitchen.

In Danish, the definite article is often added as an ending:

• et køkken = a kitchen
• køkkenet = the kitchen

Because English says in the kitchen, Danish uses the definite form køkkenet.

Før means before.

It introduces the time clause:

• før gæsterne kommer = before the guests arrive / come

So the whole sentence says that the speaker wants to tidy up before that later event happens.

Gæsterne means the guests.

It is the definite plural form:

• en gæst = a guest
• gæster = guests
• gæsterne = the guests

Just like køkkenet, Danish often marks definiteness with an ending instead of a separate word like the.

Because før introduces a subordinate clause.

In Danish subordinate clauses, the subject usually comes before the verb:

• før gæsterne kommer

Compare that with main clause word order, where Danish often uses verb-second order:

• Gæsterne kommer snart
• Snart kommer gæsterne

But after før, you use normal subordinate clause order:

• før gæsterne kommer

It can be understood as either come or arrive, depending on how natural the English translation is.

In this context:

• før gæsterne kommer usually means before the guests arrive

Even though the Danish verb is literally come, English often translates it as arrive in this kind of situation.

After modal verbs like vil, Danish uses the infinitive without a separate word like English to.

So:

• Jeg vil rydde op not
• Jeg vil at rydde op

This is similar to English:

• I want to tidy up but with Danish modal verbs it behaves more like:
• I will go where English also does not use to after will.

Sometimes yes, but in this sentence want to is the more natural interpretation.

Vil can express:

• desire: want to
• willingness: be willing to
• future meaning in some contexts: will

Here, because the sentence sounds like a personal plan or intention, want to tidy up is the most likely meaning.

You could still use vil, but Danish often uses the present tense for future meaning if the context is clear.

For example:

• Jeg rydder op i køkkenet, før gæsterne kommer.

This can mean I’m tidying up / I’ll tidy up in the kitchen before the guests come.

So:

• vil rydde op = stronger sense of intention/wish
• rydder op = simple plan or future action from context

A few words may be tricky for English speakers:

• jeg: often sounds more like yai or yeye depending on accent and speech style, not like a hard English j
• vil: the i is short
• rydde: the y sound does not exist in English; it is a rounded front vowel
• køkkenet: ø is also a special Danish vowel
• gæsterne: æ sounds somewhat like the vowel in cat, but not exactly
• kommer: the r is Danish, not an English r

If you are learning pronunciation, the vowels in rydde, køkkenet, and gæsterne are especially worth practicing.

Yes. Inden gæsterne kommer also means before the guests come/arrive.

Both før and inden can mean before, though før is very common and straightforward here.

So these are both natural:

• Jeg vil rydde op i køkkenet, før gæsterne kommer.
• Jeg vil rydde op i køkkenet, inden gæsterne kommer.

Yes, very natural. It sounds like something a native speaker could easily say in everyday life.

It uses:

• common vocabulary
• normal word order
• a very typical time clause with før
• a very common expression: rydde op

So it is a good model sentence for everyday Danish.
