Han viser oss trikset.

Yes. Han is the Norwegian subject pronoun meaning he.

In this sentence, han is the one doing the action, so it is the subject.

Compare:

• han = he
• ham = him in some traditional grammar, though in modern Bokmål people often use han in many places where English would use him

In a basic sentence like this, han straightforwardly means he.

Viser is the present tense of the verb å vise, which means to show.

So:

• å vise = to show
• viser = shows / is showing

Norwegian present tense is often simple:

• Han viser oss trikset = He shows us the trick or He is showing us the trick

Unlike English, Norwegian usually does not need a separate form like is showing for an action happening right now. The plain present tense often covers both meanings.

Because oss is the object form of we.

Compare the pronouns:

• vi = we (subject form)
• oss = us (object form)

In this sentence, he is showing something to us, so Norwegian uses oss, just like English uses us rather than we.

Compare:

• Vi ser trikset. = We see the trick.
• Han viser oss trikset. = He shows us the trick.

Because trikset is the definite form of et triks.

In Norwegian, the equivalent of the is often added to the end of the noun instead of appearing as a separate word.

Here is the pattern:

• et triks = a trick
• trikset = the trick

So the ending -et marks that the noun is:

• neuter (because triks takes et)
• definite (the)

This is one of the biggest differences from English.

Because Norwegian usually expresses definiteness by attaching it to the noun.

English:

• the trick

Norwegian:

• trikset

So instead of a separate article before the noun, Norwegian often uses a suffix:

• en bil = a car
• bilen = the car
• et hus = a house
• huset = the house
• et triks = a trick
• trikset = the trick

A separate determiner can appear in other structures, but in this simple sentence, trikset alone already means the trick.

The word order is:

subject + verb + indirect object + direct object

So:

• Han = subject
• viser = verb
• oss = indirect object
• trikset = direct object

This is very natural in Norwegian and works much like English:

• He shows us the trick

You can think of oss as the person receiving the showing, and trikset as the thing being shown.

Yes, that is also grammatical.

Both are possible:

• Han viser oss trikset
• Han viser trikset til oss

The first version is often the most direct and natural when you have both objects together.

The second version uses til oss = to us, which can sometimes sound a bit more explicit or place a little more focus on us.

So:

• Han viser oss trikset = He shows us the trick
• Han viser trikset til oss = He shows the trick to us

Both are correct.

Yes, triks is a common word meaning trick.

Its gender is neuter, which is why it uses et in the indefinite singular:

• et triks = a trick

And then:

• trikset = the trick

That is why the sentence does not say triksen. The noun is not a common-gender en noun; it is a neuter et noun.

Yes. In many contexts, the Norwegian present tense can translate into either English form.

So:

• Han viser oss trikset can mean He shows us the trick
• or He is showing us the trick

The exact meaning depends on context.

If you need to make the ongoing action extra clear, Norwegian can add something else, but very often the plain present tense is enough.

Then you would use the indefinite form:

• Han viser oss et triks.

Compare:

• et triks = a trick
• trikset = the trick

So the only change is the noun phrase:

• Han viser oss trikset. = He shows us the trick.
• Han viser oss et triks. = He shows us a trick.

Yes, it is completely natural.

It is a simple, standard Norwegian sentence with:

• a subject (han)
• a present-tense verb (viser)
• an indirect object (oss)
• a definite direct object (trikset)

A native speaker would understand it immediately, and it sounds normal in both spoken and written Bokmål.
