Han insisterer på svaret.

Insisterer is the present tense form of the verb å insistere (to insist).

• å insistere = infinitive, to insist
• insisterer = present tense, insists / is insisting

So:

• Han insisterer = He insists

In Norwegian, the present tense often ends in -r.

Because å insistere på is the normal Norwegian pattern for to insist on.

So the verb commonly goes with this preposition:

• insistere på noe = insist on something
• insistere på å gjøre noe = insist on doing something

Even if English sometimes phrases things a little differently, in Norwegian på is the usual choice here.

Svaret is the definite form of svar.

• et svar = an answer
• svaret = the answer

Norwegian usually adds the definite article to the end of the noun instead of putting a separate word before it.

So:

• svar = answer
• svaret = the answer

In Norwegian, the definite article is usually attached to the noun.

For neuter nouns like svar, the pattern is:

• et svar = an answer
• svaret = the answer

This is one of the most important differences from English. Instead of saying a separate word like the, Norwegian often puts the definiteness at the end of the noun.

Because svar is a neuter noun in Norwegian.

That means:

• et svar = an answer
• svaret = the answer

Unfortunately, grammatical gender often has to be learned with each noun. A good habit is to memorize nouns together with their article:

• et svar
• en bok
• ei/en dør, etc.

The word order is:

Subject + verb + prepositional phrase

• Han = subject
• insisterer = verb
• på svaret = prepositional phrase

So:

• Han | insisterer | på svaret

This is the normal word order for a simple statement in Norwegian.

Because han is the subject form of the pronoun.

• han = he
• ham = him

Since he is the one doing the action (insisting), Norwegian uses han.

Compare:

• Han insisterer. = He insists.
• Jeg ser ham. = I see him.

No. In modern Norwegian, the verb form normally stays the same regardless of the subject.

So you get:

• Jeg insisterer
• Du insisterer
• Han insisterer
• Vi insisterer

This is simpler than English, because you do not need a special -s form for he/she/it.

Yes, grammatically it is fine. But in real life, the exact context matters.

It suggests that he is insisting on the answer specifically, as if a particular answer is already known or expected.

Depending on context, Norwegian speakers might also say things like:

• Han insisterer på et svar. = He insists on an answer.
• Han krever et svar. = He demands an answer.

So your sentence is correct, but the definite form svaret makes it sound specific.

A simple learner-friendly pronunciation is roughly:

SVAH-ret

A few helpful points:

• svar has a long vowel sound
• the r is pronounced, though how it sounds can vary by dialect
• the ending -et in svaret is the definite ending for a neuter noun

If you are learning Bokmål pronunciation, focus on saying it clearly as two parts:

• svar
• -et

Not here. In this sentence, på belongs with the verb insistere på.

So på svaret means on the answer, not about the answer.

This is a good example of why prepositions often need to be learned together with the verb:

• å tenke på = to think about
• å stole på = to trust / rely on
• å insistere på = to insist on

The exact English translation of på depends on the expression.

Yes. Norwegian often forms yes/no questions by putting the verb before the subject.

Statement:

• Han insisterer på svaret.

Question:

• Insisterer han på svaret? = Does he insist on the answer?

That verb-first pattern is very common in Norwegian questions.
