Værsgo, her er formularen.

Here, værsgo means something like here you are, there you go, or please when you hand something to someone.

It is a very common Danish word used when:

• giving someone an object
• serving food or drink
• letting someone go first
• inviting someone to take something

So in Værsgo, her er formularen, the speaker is politely handing over the form.

Yes. Værsgo is the common contracted form of vær så god.

You will often hear and see værsgo in everyday Danish because it sounds more natural in normal speech. The full form vær så god is still correct, but it can sound a little more careful, more formal, or simply less reduced.

So:

• vær så god = full form
• værsgo = usual everyday form

Because værsgo is functioning like a separate polite expression or interjection before the main clause.

So the sentence is really in two parts:

• Værsgo
• her er formularen

The comma helps show that short pause: Værsgo, her er formularen.

In speech, you would usually pause slightly after værsgo.

Literally, it means here is the form.

Breaking it down:

• her = here
• er = is
• formularen = the form

So the whole sentence is very close to English: Værsgo, her er formularen. = Here you are, here is the form.

Because Danish main clauses usually follow the verb-second rule.

That means the finite verb usually comes in the second position of the clause. Here:

• first position: her
• second position: er
• then: formularen

So:

• Her er formularen = correct
• Her formularen er = not normal Danish word order

This is actually similar to English in this particular expression: Here is the form, not Here the form is.

The ending -en makes the noun definite, so formularen means the form.

Compare:

• en formular = a form
• formularen = the form

Danish often puts the definite article at the end of the noun instead of using a separate word like English the.

So:

• English: the form
• Danish: formularen

Yes, but it means something different.

• Her er formularen = Here is the form
  This suggests a specific form that both speaker and listener already know about.

• Her er en formular = Here is a form
  This sounds more indefinite, as if it is just one form among others, or the listener did not know which form to expect.

In many real situations, formularen sounds more natural if a specific document is being handed over.

A rough English-friendly guide is VAIRS-go.

A few important points:

• the first part is stressed
• the æ sound is not exactly an English vowel
• in natural speech, the word is quite compressed

So even though it comes from vær så god, native speakers usually say it as one quick word: værsgo.

If you say something close to VAIRS-go, people will understand you well.

Yes, it is natural and useful.

It sounds like something a receptionist, clerk, teacher, or office worker might say when handing someone a document: Værsgo, her er formularen.

The only thing to note is that formular is understandable, but in some contexts Danes may also use blanket for an official form.

So this sentence is perfectly fine, but depending on the situation, you might also hear: Værsgo, her er blanketten.

Her er means here is / here are, and it points to something near the speaker or being presented right now.

Der er often means there is / there are, and it is also used for general existence.

Compare:

• Her er formularen. = Here is the form.
• Der er en formular på bordet. = There is a form on the table.

In your sentence, her er is the natural choice because the speaker is directly giving or showing the form to someone.
