Barnet kaster steinen.

In Norwegian, the definite article is usually attached to the end of the noun instead of being a separate word in front.

So:

• barnet = the child
• steinen = the stone

This is one of the biggest differences from English. English says the child; Norwegian often says child-the in effect.

If the nouns were indefinite, you would normally have:

• et barn = a child
• en stein = a stone

Because barn by itself usually means child in an indefinite sense, while barnet means the child.

The ending -et is the definite singular ending for many neuter nouns.

So:

• barn = child / a child
• barnet = the child

The noun barn is a neuter noun, which is why it takes -et in the definite singular.

Steinen is the definite singular form of stein.

• stein = stone / a stone
• steinen = the stone

Here the ending -en marks definite singular. This is common for masculine nouns in Bokmål.

So the pattern is:

• en stein = a stone
• steinen = the stone

In Bokmål, nouns have grammatical gender, and that affects articles and endings.

In this sentence:

• barn is neuter
• stein is masculine

That is why you get:

• et barn → barnet
• en stein → steinen

Gender matters because it changes:

• the indefinite article: en / ei / et
• the definite ending: often -en / -a / -et

Kaster is the present tense of the verb å kaste = to throw.

So:

• å kaste = to throw
• kaster = throw / throws / is throwing depending on context

Unlike English, Norwegian verbs do not change depending on the subject.

So you would say:

• jeg kaster = I throw
• du kaster = you throw
• barnet kaster = the child throws

The verb form stays kaster.

Yes, very often it can.

Norwegian present tense often covers both:

• Barnet kaster steinen = The child throws the stone
• depending on context, it can also be understood as The child is throwing the stone

If you specifically want to emphasize an ongoing action, Norwegian can sometimes use other structures, but the simple present is very common and flexible.

Yes. This sentence uses the normal basic word order:

• Subject + Verb + Object

So:

• Barnet = subject
• kaster = verb
• steinen = object

That gives:

• Barnet kaster steinen.

Norwegian relies a lot on word order to show who is doing the action and what is being acted on.

Also, Norwegian is a V2 language, which means the finite verb is normally in the second position in main clauses. In this sentence, that rule is satisfied because the subject comes first and the verb comes second.

It would usually be:

• Et barn kaster en stein.

That means A child throws a stone.

Compare:

• Barnet kaster steinen. = The child throws the stone.
• Et barn kaster en stein. = A child throws a stone.

This is a useful contrast because it shows both ways Norwegian marks nouns:

• indefinite: separate article in front
• definite: ending attached to the noun

A rough English-friendly guide would be:

• Barnet ≈ BAR-neht
• kaster ≈ KAH-ster
• steinen ≈ STY-nehn or STINE-en, depending on accent

A few important notes:

• The r is pronounced, but how it sounds depends on the dialect.
• stein has a vowel sound a bit like English stine.
• Norwegian pitch and rhythm matter, so the exact sound varies by region.

If you want a safe beginner goal, focus on saying the words clearly and keeping the stress near the start of each word:

• BAR-net KAS-ter STEI-nen

Yes. That would mean The child throws a stone.

So the combinations work like this:

• Barnet kaster steinen = The child throws the stone
• Barnet kaster en stein = The child throws a stone
• Et barn kaster steinen = A child throws the stone
• Et barn kaster en stein = A child throws a stone

Changing just the noun form changes whether it is definite or indefinite.
