Hun viser lojalitet.

Hun is the subject form, like she in English.

• Hun viser lojalitet = She shows loyalty
• Jeg ser henne = I see her

So here, she is the one doing the action, which is why Norwegian uses hun.

Viser is the present tense of the verb å vise.

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

Norwegian verbs do not change according to the subject the way English verbs do. So:

• jeg viser = I show
• du viser = you show
• hun viser = she shows
• vi viser = we show

The verb form stays viser for all of them in the present tense.

Because lojalitet is being used as an uncountable abstract noun, like loyalty in English.

In English, you also normally say:

• She shows loyalty

not:

• She shows a loyalty

So Norwegian works the same way here.
Lojalitet means the general quality or trait of loyalty, not one specific loyalty.

This is the normal Norwegian word order for a simple statement:

Subject + verb + object

So:

• Hun = subject
• viser = verb
• lojalitet = object

This is very similar to English:

• She shows loyalty

Norwegian often follows this basic pattern in ordinary main clauses.

The infinitive is å vise.

Examples:

• Hun viser lojalitet. = She shows loyalty.
• Hun vil vise lojalitet. = She wants to show loyalty.
• Det er viktig å vise lojalitet. = It is important to show loyalty.

The å is the infinitive marker, like to in English.

Yes, lojalitet is a noun, and it is typically an en-word in Norwegian:

• en lojalitet
• lojaliteten = the loyalty

That said, in this sentence you usually just use the bare noun lojalitet, because it is abstract and uncountable.

• lojalitet = loyalty, in a general sense
• lojaliteten = the loyalty, a specific loyalty

So:

• Hun viser lojalitet. = She shows loyalty.
• Hun viser lojaliteten sin til laget. = She shows her loyalty to the team.

In your sentence, the indefinite form is used because the speaker is talking about the quality in general.

Yes, and it is very natural, but it means something slightly different in structure.

• Hun viser lojalitet. = She shows loyalty.
• Hun er lojal. = She is loyal.

The first uses a verb + noun structure.
The second uses an adjective.

They are closely related in meaning, but viser lojalitet can sound a little more focused on her behavior or actions, while er lojal describes her as a person or state.

A rough guide for an English speaker:

• viser sounds roughly like VEE-ser
• lojalitet sounds roughly like loo-yah-lee-TET

A few tips:

• v is pronounced like English v
• s in viser is a clear s sound
• the final syllable of lojalitet is stressed more strongly

Pronunciation varies somewhat by dialect, but this approximation will help you get started.

Yes. Å vise is a very common verb and can mean several related things, depending on context:

• show
• display
• point out
• demonstrate

Examples:

• Hun viser lojalitet. = She shows loyalty.
• Han viser meg veien. = He shows me the way.
• Læreren viser hvordan det gjøres. = The teacher shows how it is done.

So the exact English translation depends on what is being shown.

Normally, no. Norwegian usually keeps the subject pronoun in ordinary sentences.

So you say:

• Hun viser lojalitet.

not just:

• Viser lojalitet.

unless you are using a very informal note style, headline style, or a context where the subject is clearly omitted on purpose. In standard sentences, the subject is usually required.

Yes. In a yes/no question, Norwegian usually puts the verb before the subject:

• Viser hun lojalitet? = Does she show loyalty?

This is a very important pattern in Norwegian:

• statement: Hun viser lojalitet.
• question: Viser hun lojalitet?

So the verb moves in front of the subject.

It is a borrowed/international-type word, and it looks similar to English loyalty because both come from the same broader European vocabulary tradition.

That is common in Norwegian, especially with abstract nouns:

• lojalitet = loyalty
• aktivitet = activity
• kvalitet = quality

This can be helpful for English speakers, because many such words are recognizable even if the spelling is a little different.
