Unser Team punktet in jeder Quizrunde.

Because Team is a neuter noun in German: das Team.

The possessive unser- changes its ending depending on the gender, case, and article pattern of the noun. In the nominative singular neuter, it is:

• unser Team = our team

Compare:

• unser Team = our team
• unsere Mannschaft = our team, if the noun is feminine (die Mannschaft)
• unser Lehrer = our teacher, if the noun is masculine (der Lehrer)

So unser is correct here because Team is neuter and it is the subject of the sentence.

Because the subject is Unser Team, which is third person singular.

The verb punkten means something like to score points or to do well / rack up points. In the present tense, it is conjugated like a regular verb:

• ich punkte
• du punktest
• er/sie/es punktet
• wir punkten
• ihr punktet
• sie/Sie punkten

Since Team is treated as es grammatically, the correct form is punktet.

Here, punkten means to score, to get points, or sometimes more broadly to perform successfully.

In this sentence, with Quizrunde and the idea of points, the most natural sense is:

• to score points
• to score in every quiz round

In other contexts, punkten can be more figurative:

• Er punktet mit Humor. = He scores points with his humor.
• Die Firma punktet bei den Kunden. = The company goes over well with customers / scores points with customers.

So here it is a very natural verb for quizzes, games, competitions, and point-based activities.

It is dative.

The preposition in can take either:

• accusative for movement into something
• dative for location / being in something

Here the sentence is not about moving into a round. It means the team scores during / in each quiz round, so German uses dative:

• in jeder Quizrunde

Since Quizrunde is feminine (die Quizrunde), the dative singular form is:

• jeder Quizrunde

Compare:

• in die Quizrunde = into the quiz round (accusative, movement)
• in der Quizrunde = in the quiz round (dative, location)
• in jeder Quizrunde = in every quiz round (dative, feminine singular after jeder)

Because Quizrunde is in the dative singular here, not nominative or accusative.

The word jeder changes its ending like a der-word. For feminine singular:

• nominative: jede Quizrunde
• accusative: jede Quizrunde
• dative: jeder Quizrunde
• genitive: jeder Quizrunde

So:

• jede Quizrunde = every quiz round, as subject or direct object
• in jeder Quizrunde = in every quiz round

The preposition in here requires the dative, so jeder is correct.

Yes, Quizrunde is one word because German often forms compound nouns.

It combines:

• Quiz = quiz
• Runde = round

So:

• Quizrunde = quiz round

This is extremely common in German. English often uses separate words where German prefers one combined noun. Other examples:

• Fußballspiel = football game / soccer match
• Sprachkurs = language course
• Hausaufgabenheft = homework notebook

When learning German, it helps to look for the smaller parts inside a long noun.

Yes, the phrase in jeder Quizrunde could come first.

German main clauses usually place the finite verb in second position. In the given sentence:

• Unser Team = position 1
• punktet = position 2
• in jeder Quizrunde = the rest

You can also front the prepositional phrase:

• In jeder Quizrunde punktet unser Team.

That is also correct. The verb punktet still stays in second position.

So German word order is flexible, but the conjugated verb in a main statement normally stays in position 2.

In this sentence, Team is grammatically singular in German.

That is why the verb is singular:

• Unser Team punktet.

If you wanted plural, you would say:

• Unsere Teams punkten. = Our teams score.

German usually treats collective nouns like Team as singular when they are grammatically singular, even if they refer to several people acting together.

Yes, that is possible, but the nuance is slightly different.

• Team is a very common borrowing and sounds natural in many modern contexts.
• Mannschaft is also common, especially for sports teams, and is grammatically feminine.

So you would say:

• Unser Team punktet ...
• Unsere Mannschaft punktet ...

Notice the possessive changes because Mannschaft is feminine:

• die Mannschaft
• unsere Mannschaft

Both are grammatical, but Team is probably the more neutral choice in a quiz context.

A rough English-friendly guide:

• punktet ≈ POONK-tet
• Quizrunde ≈ KVITS-roon-duh

A few details:

• u in punktet is not like English uh; it is a shorter, rounder vowel.
• qu in Quiz is usually pronounced kv in German.
• The z sound in Quiz is like ts.
• The final -e in Runde is a light uh sound, not silent.

If you say something close to OON-ser team POONK-tet in YAY-der KVITS-roon-duh, you will be understandable.

Yes. In German, in often has a broader meaning than literal physical location.

Here, in jeder Quizrunde is best understood as:

• in every quiz round
• during every quiz round
• throughout each quiz round

So this is not about being physically inside something. It refers to the context or stage of the event where the team scores.

It is in the present tense, but in German the present tense often covers both:

• what is happening now
• what happens regularly or habitually

So Unser Team punktet in jeder Quizrunde can mean:

• Our team is scoring in every quiz round.
• Our team scores in every quiz round.
• Our team keeps scoring in every quiz round.

German uses the simple present for all of these unless there is a need to make the timing more specific.

Yes. Although it literally relates to points, it is often used more generally to mean to make a good impression or to succeed in a noticeable way.

For example:

• Sie punktet mit Fachwissen. = She scores points with her expertise.
• Das Restaurant punktet durch guten Service. = The restaurant stands out because of good service.

But in your sentence, because of Quizrunde, the literal idea of scoring points is the most likely meaning.
