Jeg vil vedlægge dokumentationen.

• Jeg = subject pronoun, I
• vil = modal verb, usually will / want to
• vedlægge = main verb in the infinitive, to attach / to enclose
• dokumentationen = direct object, the documentation

So the structure is:

subject + modal verb + infinitive + object

This is a very common Danish pattern.

Because vil is a modal verb. In Danish, modal verbs are followed by the infinitive form of the main verb.

So:

• Jeg vil vedlægge dokumentationen = I will attach the documentation
• Jeg kan vedlægge dokumentationen = I can attach the documentation
• Jeg skal vedlægge dokumentationen = I must / will have to attach the documentation

After a modal verb, the next verb does not take at.

So you say:

• Jeg vil vedlægge ...

not

• Jeg vil at vedlægge ...

It can mean either, depending on context.

In many cases, vil can express:

• future: I will
• intention / willingness: I want to / intend to

In a sentence like Jeg vil vedlægge dokumentationen, English will often translate it as I will attach the documentation. But depending on tone and situation, it can also feel like I intend to attach the documentation.

If Danish wants to make a future meaning especially clear, speakers often just use the present tense with a time reference, or use context rather than a special future form.

Because it comes after the modal verb vil.

In Danish, modal verbs such as:

• vil
• kan
• skal
• må
• bør

are followed directly by the bare infinitive.

So:

• Jeg vil vedlægge dokumentationen
• Jeg kan vedlægge dokumentationen

The infinitive form here is vedlægge.

Dokumentationen is the definite form: the documentation.

In Danish, nouns often add an ending to show definiteness.

For dokumentation:

• dokumentation = documentation
• dokumentationen = the documentation

So the -en ending here works like English the.

This is very common in Danish. Instead of a separate word like the, Danish often puts definiteness at the end of the noun.

Because -en is the definite ending for many common gender nouns.

Dokumentation is a common gender noun, so:

• indefinite: dokumentation
• definite: dokumentationen

Even though the word ends in -ion, the same rule applies. Many abstract nouns in -tion / -sion / -ion are common gender in Danish.

Usually, dokumentation is treated like documentation in English: an uncountable or mass noun in many contexts.

So dokumentationen often means:

• the documentation
• the supporting documents as a whole
• the required paperwork

If you want to refer to individual documents, Danish often uses words like:

• dokumenter = documents
• bilag = attachments / enclosures / appendices

So the sentence can sound a bit formal and administrative, referring to the documentation package rather than one single paper.

Yes, fairly formal.

Vedlægge is very common in:

• emails
• letters
• official communication
• business Danish

It means attach or enclose.

In everyday spoken Danish, people may sometimes prefer more informal wording depending on context, especially when talking about files in email. But vedlægge is completely normal and correct, especially in professional writing.

Yes, absolutely.

Jeg vedlægger dokumentationen uses the present tense, and in Danish the present tense often covers what English expresses with I am attaching or I attach.

In an email, this is often very natural:

• Jeg vedlægger dokumentationen.

It can mean something like:

• I attach the documentation
• I am attaching the documentation

Compared with Jeg vil vedlægge dokumentationen, the present tense version can sound more direct and immediate, especially if the attachment is already included.

It would normally go after the modal verb:

• Jeg vil ikke vedlægge dokumentationen.

That is a very common Danish word order:

subject + finite verb + ikke + infinitive + object

So:

• Jeg vil ikke vedlægge dokumentationen.

not:

• Jeg ikke vil vedlægge dokumentationen.

Normally, no. In a neutral main clause, the natural order is:

Jeg vil vedlægge dokumentationen.

That is: subject + finite verb + infinitive + object

Putting dokumentationen before vedlægge would sound wrong in ordinary Danish.

In a yes/no question, the finite verb comes first:

• Vil jeg vedlægge dokumentationen?

But in real life, that exact question is a little unusual unless you are asking yourself something like Am I going to attach the documentation?

A more natural question to another person would be:

• Vil du vedlægge dokumentationen? = Will you attach the documentation?

This shows a basic Danish rule: in questions, the finite verb often comes before the subject.

It is pronounced roughly like vehth-lai-guh or vehth-lie-guh, though the exact sound depends on accent and how precisely you want to imitate Danish pronunciation.

A useful point for learners: vedlægge is a single verb, and in modern standard Danish you usually treat it as one unit in sentences like this.

Its parts historically relate to ved + lægge, but in normal usage you learn it as the verb vedlægge = to attach / enclose.

So for learners, the safest approach is:

• memorize vedlægge as one vocabulary item
• use it after modals as vil vedlægge, kan vedlægge, etc.

Yes, very natural, especially in formal or semi-formal writing.

For example, in an email you might write:

• Jeg vil vedlægge dokumentationen.
• Jeg vedlægger dokumentationen.
• Dokumentationen er vedlagt. = The documentation is attached.

Of these, Jeg vedlægger dokumentationen and Dokumentationen er vedlagt are often especially common when the file is already attached.

So the sentence is correct and natural, but the best version depends on whether you mean:

• I intend to attach it or
• I have attached / am attaching it now

In this sentence, dokumentationen is the direct object, but Danish does not mark this with a special case ending the way German does.

Modern Danish has very little case marking. For nouns, what matters here is mainly:

• indefinite vs. definite
• singular vs. plural
• common gender vs. neuter

So dokumentationen is not a special accusative form. It is simply the definite singular form of dokumentation.

A very useful pattern is:

Jeg vil + infinitive + object

For example:

• Jeg vil læse bogen. = I will read the book.
• Jeg vil sende filen. = I will send the file.
• Jeg vil vedlægge dokumentationen. = I will attach the documentation.

If you remember that vil is followed by the bare infinitive, you can build many correct Danish sentences very easily.
