Der Vorname steht auf dem Ausweis.

Because der Vorname is the subject of the sentence, so it is in the nominative case.

• der Vorname = the first name / given name
• Subject = the thing that does the verb, or the thing the sentence is about

Here, the sentence is saying that the first name stands / is written on the ID card.

If it were a direct object, you would expect den Vornamen, but this sentence does not have a direct object.

Yes, stehen literally means to stand, but in German it is also commonly used for written information.

So when Germans say something like:

• Der Name steht auf dem Ausweis.
• Die Adresse steht im Formular.

they mean that the information is written there or appears there.

This is very natural in German. English usually does not say the first name stands on the ID card, but German does.

auf here means on.

German often uses auf with documents, signs, screens, and similar surfaces when something is written or printed there.

So:

• auf dem Ausweis = on the ID card
• auf dem Formular = on the form
• auf der Seite = on the page

It sounds natural because the name is thought of as appearing on the surface of the document.

Because auf takes the dative case here.

Some German prepositions, including auf, can take either:

• dative for location: where something is
• accusative for direction/movement: where something is going

In this sentence, nothing is moving. The name is simply located on the ID card. So German uses the dative:

• auf dem Ausweis = on the ID card

Compare:

• Der Vorname steht auf dem Ausweis. → location → dative
• Ich schreibe den Namen auf den Ausweis. → movement toward the surface → accusative

It is in the dative singular.

Here is the breakdown:

• base noun: der Ausweis
• after auf in a location meaning: dem Ausweis

So:

• nominative: der Ausweis
• accusative: den Ausweis
• dative: dem Ausweis

In this sentence, auf dem Ausweis is a prepositional phrase showing location.

Vorname means first name or given name.

It is the name that comes before the family name in many contexts.

Common contrasts:

• Vorname = first name / given name
• Nachname = last name / surname
• Familienname = family name / surname

So if an ID shows both names, you might see:

• Vorname
• Nachname

Ausweis usually means an ID card, identification document, or some kind of official proof of identity.

Depending on context, it can refer to different things, for example:

• a national ID card
• an employee ID
• some official pass or identification document

It is a masculine noun:

• der Ausweis

Plural:

• die Ausweise

Because they are nouns, and in German all nouns are capitalized.

That is one of the most noticeable spelling rules in German.

So in this sentence:

• Der = article
• Vorname = noun, so capitalized
• steht = verb, not capitalized
• auf dem
• Ausweis = noun, so capitalized

Yes, that is completely correct.

German word order is flexible, but the finite verb usually stays in second position in a main clause.

So both of these are correct:

• Der Vorname steht auf dem Ausweis.
• Auf dem Ausweis steht der Vorname.

The difference is mainly emphasis:

• Der Vorname ... starts with the subject
• Auf dem Ausweis ... emphasizes the location first

In both cases, steht remains the second element.

Yes.

The verb must agree with the subject, and the subject here is der Vorname, which is third person singular.

So the verb form is:

• stehen = infinitive
• er/sie/es steht = third person singular

Compare:

• Der Vorname steht auf dem Ausweis.
• Die Vornamen stehen auf dem Formular.

Singular subject → steht
Plural subject → stehen

It is possible in some contexts, but steht auf dem Ausweis is more idiomatic when talking about printed or written information.

• ist auf dem Ausweis focuses more on the fact that it is present there
• steht auf dem Ausweis sounds more natural for text that is written on a document

So learners should understand that stehen is often the preferred verb for information that appears in writing.

In standard written German, auf dem normally stays auf dem.

There is a colloquial spoken contraction aufm, but that is informal and not usually what learners should write in normal standard German.

So for standard German, use:

• auf dem Ausweis

Useful comparison:

• in dem → often contracts to im
• an dem → often contracts to am
• auf dem → usually stays auf dem in standard writing

You would simply replace Vorname with Nachname:

• Der Nachname steht auf dem Ausweis.

The grammar stays the same:

• der Nachname = subject, nominative
• steht = singular verb
• auf dem Ausweis = location, dative after auf
