Unser Teamname steht oben.

Because Teamname is a masculine singular noun in German: der Teamname.

The possessive determiner has to match the noun’s gender, number, and case. Here, Teamname is the subject of the sentence, so it is in the nominative case.

That gives:

• unser Teamname = our team name

Compare:

• unser Hund = our dog
• unsere Katze = our cat
• unser Haus = our house

So unser is correct because Teamname is masculine singular nominative.

It is in the nominative case.

In Unser Teamname steht oben, Teamname is the thing doing the verb steht, so it is the subject of the sentence.

A simple way to see it:

• What stands above / at the top?
• Our team name

That means Teamname is nominative.

German often uses stehen where English would more naturally use be in some contexts involving written or printed things.

So:

• Unser Teamname steht oben.

literally feels like:

• Our team name stands at the top / above.

But idiomatically it means:

• Our team name is at the top.

This use of stehen is very common for text or information that appears somewhere:

• Das steht auf der Seite. = That is written on the page.
• Mein Name steht hier. = My name is here / written here.

So steht suggests that the name is written or displayed in that position.

Oben means above, up top, or at the top, depending on context.

In this sentence, the most natural meaning is:

• at the top
• up above

So Unser Teamname steht oben means the team name is located higher up, probably on a page, screen, board, or list.

Related words:

• oben = up / above / at the top
• unten = down / below / at the bottom

Example:

• Der Titel steht oben. = The title is at the top.
• Die Erklärung steht unten. = The explanation is at the bottom.

Yes. German very often forms compound nouns by writing them as one word.

So:

• Team
  • Name → Teamname

This is completely normal in German.

Other examples:

• Haus
  • Tür → Haustür = house door / front door
• Kinder
  • Garten → Kindergarten
• Familie
  • Name → Familienname = family name / surname

English often writes such combinations as two words, but German usually combines them into one.

Because German main clauses usually follow the verb-second rule (V2).

In a normal statement, the conjugated verb comes in the second position:

• Unser Teamname | steht | oben

The first position can be taken by the subject or by another element, but the verb still stays second.

For example:

• Unser Teamname steht oben.
• Oben steht unser Teamname.

Both are grammatical. The second version emphasizes oben.

Yes, absolutely.

Both of these are correct:

• Unser Teamname steht oben.
• Oben steht unser Teamname.

The difference is mainly emphasis:

• Unser Teamname steht oben. → neutral statement
• Oben steht unser Teamname. → emphasizes the location up top

This is a good example of German word order flexibility, as long as the finite verb stays in second position.

Steht is the 3rd person singular form of stehen.

The infinitive is:

• stehen = to stand

Present tense:

• ich stehe
• du stehst
• er/sie/es steht
• wir stehen
• ihr steht
• sie/Sie stehen

Since unser Teamname is a singular noun, the verb must also be singular:

• Unser Teamname steht oben.

Then the possessive determiner and the verb would change.

For example:

• Unsere Teamnamen stehen oben.
• Our team names are at the top.

Changes:

• unser → unsere because Teamnamen is plural
• steht → stehen because the subject is plural

So the sentence is a useful model for agreement:

• singular: unser Teamname steht
• plural: unsere Teamnamen stehen

A little, yes.

Because Team is a loanword, many speakers pronounce it close to the English-style teem, while Name is a normal German word.

So Teamname is roughly:

• teem-nah-muh

A few helpful points:

• ea in Team is pronounced like a long ee
• a in Name is long
• the final -e in Name is pronounced as a soft uh sound in German

So it does not sound like English name.

Yes, definitely. That is one of the most natural uses here.

In German, stehen is often used for things that are written, printed, displayed, or listed somewhere.

So Unser Teamname steht oben could mean:

• our team name is written at the top of the page
• our team name appears at the top of the screen
• our team name is listed above

It does not necessarily mean that something is physically standing upright. In sentences like this, it often refers to placement in text or layout.
