Kan De bestille et bord på restauranten til fredag?

De means you here, but it is the formal/polite version. It is capitalized to distinguish it from de, which usually means they.

So:

• De = formal you
• de = they

In modern everyday Danish, De is quite formal and can sound old-fashioned in many situations.

Most often, you would use du instead of De:

Kan du bestille et bord på restauranten til fredag?

That is the normal informal way to say it to one person. If you are speaking to more than one person, you could use I: Kan I bestille et bord på restauranten til fredag?

Because this is a yes/no question. In Danish, yes/no questions usually begin with the finite verb.

So:

• Statement: De kan bestille et bord på restauranten til fredag.
• Question: Kan De bestille et bord på restauranten til fredag?

This is similar to English word order in Can you book a table...?

It can be both, just like English Can you ...?

Literally, it asks about ability: Are you able to book a table...?
But in normal use, it often works as a polite request: Could you book a table...?

So the exact force depends on context.

Because after a modal verb like kan, Danish normally uses the infinitive without at.

So:

• kan bestille = can book
• not kan at bestille

This is like English, where we say can book, not can to book.

Other common Danish modal verbs work the same way:

• vil bestille = want to book
• skal bestille = have to / will book
• må bestille = may / must book

It can mean different things depending on context. Here, bestille et bord means book or reserve a table.

So in this sentence, bestille does not mean order food.
It means arranging to have a table available in advance.

Because bord is a neuter noun in Danish, so it takes et in the indefinite singular.

Danish nouns have two grammatical genders:

• en words
• et words

So:

• et bord = a table
• bordet = the table

You simply have to learn the gender with the noun.

In Danish, the definite article is often added as an ending to the noun instead of being a separate word.

So:

• en restaurant = a restaurant
• restauranten = the restaurant

This is very common in Danish. English uses a separate word (the), but Danish often adds the ending directly to the noun.

På restauranten is the most natural choice here. With places like restaurants, schools, offices, and similar locations, Danish often uses på where English might expect at.

So:

• på restauranten = at the restaurant

I restauranten would focus more on being inside the restaurant physically.
For booking a table at that venue, på restauranten is the idiomatic choice.

Here, til fredag means for Friday. It fits the idea of making a reservation intended for that day.

So:

• bestille et bord til fredag = book a table for Friday

You may also hear på fredag in other contexts, meaning on Friday, especially when talking about when something happens. But with reservations and arrangements, til fredag is very natural because it points to the intended date.

In Danish, days of the week are usually used without an article.

So:

• fredag = Friday
• til fredag = for Friday

This is similar to English, where we also usually say Friday, not the Friday, unless we mean a very specific one in a special context.

No. Danish verbs are much simpler in this way. The verb usually stays the same no matter who the subject is.

For example:

• jeg kan
• du kan
• De kan
• vi kan

So kan does not change for person. That is why Kan De ...? uses the same kan you would use with other subjects.
