Han kjøper en cola.

Kjøper is the present tense form of the verb å kjøpe (to buy).

• å kjøpe = to buy
• kjøper = buys / is buying

In Norwegian, verbs are not conjugated differently for different persons the way they are in English. So you get:

• jeg kjøper = I buy / I am buying
• du kjøper = you buy / you are buying
• han kjøper = he buys / he is buying

So kjøper is used because the sentence is in the present tense.

Han is the subject pronoun, meaning he. In a basic Norwegian statement, the usual word order is:

subject + verb + object

So here:

• Han = subject
• kjøper = verb
• en cola = object

This is the same basic order as in English: He buys a cola.

In Norwegian, singular countable nouns usually need an article when they are indefinite, just as in English.

So:

• en cola = a cola
• colaen = the cola

You would normally not say just cola in this sentence, because cola is being used as one countable item, so it takes the indefinite article en.

Norwegian nouns have grammatical gender, and cola is treated as a common-gender noun in this sentence. Common-gender nouns usually take en in the indefinite singular.

So:

• en cola = a cola

In Bokmål, many nouns are either:

• en words (common gender)
• et words (neuter)
• and some speakers/writers also distinguish feminine nouns separately with ei

For cola, using en is normal.

It is basically a loanword. Norwegian uses many international words, and cola is one of them. Even when a word is borrowed, it still follows Norwegian grammar.

That means it can take:

• an article: en cola
• a definite ending: colaen

So even though the word looks familiar to an English speaker, it behaves like a Norwegian noun in the sentence.

This is one of the trickier parts for English speakers.

A rough guide:

• kj in many Norwegian words is pronounced somewhat like a soft hy sound
• ø is a vowel that does not exist in standard English
• -er at the end is usually a reduced ending in normal speech

A very rough approximation might be something like:

HYUR-per or HYOH-per, but neither is exact.

A few details:

• kj: put your tongue in a position similar to saying h and y together very softly
• ø: similar to the vowel in French peu or German schön, if you know those
• stress: KJØ-per

The exact pronunciation depends somewhat on dialect, but the spelling-to-sound connection here is very typical of Norwegian.

It can mean either, depending on context.

Norwegian present tense often covers both:

• he buys
• he is buying

So Han kjøper en cola could mean:

• he buys a cola
• he is buying a cola

Norwegian often does not force you to choose between simple present and present progressive the way English does.

Because Han is a pronoun, not a noun. Articles like en and et are used with nouns, not with personal pronouns.

Compare:

• Han kjøper en cola = He buys a cola
• Mannen kjøper en cola = The man buys a cola

So han stands on its own and does not need an article.

Yes. This sentence is a very useful model:

Han + present-tense verb + en/et + noun

Examples:

• Han kjøper en kaffe. = He buys a coffee.
• Han kjøper en brus. = He buys a soda.
• Han kjøper et eple. = He buys an apple.

Notice that the article changes depending on the noun:

• en for many common-gender nouns
• et for neuter nouns

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

Statement:

• Han kjøper en cola.

Question:

• Kjøper han en cola?

So Norwegian often changes word order to form questions, much like English does with Is he... ?, Does he... ?, and so on.

This is standard Bokmål.

In Nynorsk, the equivalent would typically be:

• Han kjøper ein cola.

The main difference here is the article:

• Bokmål: en
• Nynorsk: ein

A learner will most commonly see Han kjøper en cola in Bokmål materials.
