Mit navn står øverst på formularen.

Because navn is a neuter noun in Danish: et navn.

Danish possessives agree with the gender and number of the noun:

• min for common gender singular
• mit for neuter singular
• mine for plural

So:

• min bil = my car
• mit navn = my name
• mine bøger = my books

Since navn is neuter, mit is the correct form.

Because Danish usually adds definiteness to the end of the noun instead of using a separate word like English the.

• en formular = a form
• formularen = the form

So på formularen literally looks like on form-the, but in natural English it is on the form.

This is a very common Danish pattern.

In Danish, verbs like stå (stand), ligge (lie), and sidde (sit) are often used where English would simply say is.

Here, står suggests that the name is written/shown/positioned somewhere on the form. Danish often uses stå for text or information appearing on a page.

So:

• Mit navn står på formularen = My name is on the form
• more literally: My name stands on the form

This is normal idiomatic Danish, not unusually poetic or formal.

Øverst means at the top or topmost.

In this sentence, it tells you where the name appears on the form: at the top of it.

You can think of it as an adverb of position here:

• øverst = at the top
• nederst = at the bottom

Examples:

• Mit navn står øverst. = My name is at the top.
• Underskriften står nederst på siden. = The signature is at the bottom of the page.

Because the name is understood as being written on the surface of the form, not inside it in a physical sense.

Danish often uses på for text, labels, and things appearing on documents, pages, signs, and screens.

• på formularen = on the form
• på siden = on the page
• på skærmen = on the screen

Using i would usually suggest something more like inside the form or within its contents, which is less natural here.

This is the normal Danish word order for a main clause:

subject + verb + other elements

So here:

• Mit navn = subject
• står = verb
• øverst på formularen = location

A very important Danish rule is that the finite verb is usually in second position in main clauses.

This sentence follows that pattern neatly.

You could also rearrange it for emphasis:

• Øverst på formularen står mit navn.

That is also correct, but then står still has to stay in second position.

Yes, that would be understandable, but står is more idiomatic in this context.

• er simply states location or existence
• står gives the sense that the name is placed/written there

So:

• Mit navn er øverst på formularen = understandable
• Mit navn står øverst på formularen = more natural if you are talking about what is written on the form

Danish often prefers these more specific position verbs where English might just use is.

Står is the present tense of stå.

The forms are:

• infinitive: stå = to stand
• present: står = stand / is standing
• past: stod = stood / was standing
• past participle: stået = stood

In this sentence, present tense is used because it describes the current state of the form.

Here it functions adverbially, because it describes where the name stands.

It comes from the idea of uppermost/topmost, but in sentences like this it behaves like a location word:

• Billedet hænger øverst. = The picture hangs at the top.
• Mit navn står øverst på formularen. = My name is at the top of the form.

So for a learner, it is easiest to understand øverst here as a position adverb.

The letter ø is one of the sounds English speakers often find difficult.

A rough guide:

• ø is a rounded front vowel
• it is somewhat similar to the vowel in French deux or German schön, if you know those
• it does not sound like English o

In står, the å is a different vowel, more like a broad aw sound.

So the two words have different key vowels:

• øverst → contains ø
• står → contains å

If you are practicing, it helps to learn ø and å as completely separate sounds rather than trying to match them both to English o.
