Næringsvirksomheten har flere kunder.

Because Norwegian usually writes compound nouns as one word.

Here, the word is built like this:

• næring = trade, industry, business
• virksomhet = activity, operation, business
• næringsvirksomhet = business activity / commercial operation
• næringsvirksomheten = the business activity / the commercial operation

The -s- in the middle is a common linking sound/letter in Norwegian compounds. It does not usually have a meaning by itself; it just helps connect the parts.

The -en is the definite article attached to the noun. In Norwegian, the is often added to the end of the noun instead of appearing as a separate word in front.

Compare:

• en næringsvirksomhet = a business / a commercial operation
• næringsvirksomheten = the business / the commercial operation

So English the is built into the Norwegian noun here.

Because Norwegian often marks definiteness with an ending on the noun.

So instead of saying something like the business, Norwegian commonly says:

• virksomheten = the business
• kunden = the customer
• kundene = the customers

This is completely normal Norwegian grammar.

It is singular definite.

You can see that from the ending -en. The sentence is talking about one business/activity, not several.

A quick comparison:

• en kunde = a customer
• kunden = the customer
• kunder = customers
• kundene = the customers

The same singular/plural idea applies to næringsvirksomhet as well.

Har is the present tense of å ha, which means to have.

So:

• jeg har = I have
• du har = you have
• han/hun har = he/she has
• de har = they have

Unlike English, the verb does not change depending on the subject. So har stays the same.

Flere usually means more or several, depending on context.

It is related to the idea of a larger number:

• mange kunder = many customers
• flere kunder = more customers / several customers

If there is a comparison in the wider context, flere often means more.
If there is no clear comparison, it can sometimes feel closer to several.

So the exact best English translation depends on context, even though the Norwegian word is the same.

Because kunder is the indefinite plural form: customers.

Compare:

• en kunde = a customer
• kunden = the customer
• kunder = customers
• kundene = the customers

So flere kunder means more customers or several customers, not the customers.

Yes. This is a very normal Norwegian sentence pattern:

• Næringsvirksomheten = subject
• har = verb
• flere kunder = object

So it follows the basic subject + verb + object order:

• Næringsvirksomheten har flere kunder.

That is very similar to English: The business has more customers.

It is understandable, but it sounds fairly formal, administrative, or legal/business-like.

In everyday language, people might more often say something like:

• bedriften = the company
• firmaet = the company / the firm
• butikken = the shop/store

So næringsvirksomheten is not wrong, but it has a more official or abstract tone.

It is best to think of it as a set expression meaning something like:

• business activity
• commercial activity
• a business operation

Even though you can break it into parts, the full compound is often used as a standard term, especially in formal contexts such as law, tax, administration, or business writing.

So a learner should understand both:

• the parts of the word
• the fact that the whole compound functions as one vocabulary item

A good strategy is to split it into chunks:

• nærings
• virksomheten

Or even smaller:

• næ-ring-s
• virk-som-he-ten

You do not need to say it super fast. Norwegian compounds can be long, and native speakers are used to them.

The most important thing is to keep the parts clear rather than trying to make it sound like one rushed blur.
