Bien sitter på blomsten.

The ending -en marks the definite singular in Norwegian, so:

• bien = the bee
• blomsten = the flower

Unlike English, Norwegian often puts the at the end of the noun instead of using a separate word.

Compare:

• en bi = a bee
• bien = the bee
• en blomst = a flower
• blomsten = the flower

Because in Norwegian, the definite article is usually attached to the noun as a suffix.

So instead of saying something like the bee, Norwegian normally says:

• bi + en = bien

and instead of the flower:

• blomst + en = blomsten

This is one of the biggest differences from English noun structure.

Sitter is the present tense of å sitte.

So it can mean:

• sits
• is sitting

Norwegian usually does not need a separate progressive form like English is sitting. The simple present often covers both meanings, and context tells you which one is intended.

Norwegian often prefers a position verb where English might simply use is.

Here, sitter describes how the bee is positioned on the flower. For small animals, birds, insects, and things resting somewhere, sitte is very commonly used.

So:

• Bien sitter på blomsten = the bee is sitting/on the flower

If you said Bien er på blomsten, it would mean The bee is on the flower, which is understandable, but it is less natural if you want to describe its position in the typical Norwegian way.

Yes. In Norwegian, sitte is often used more broadly than English sit.

It can be used for:

• people sitting
• birds sitting on a branch
• insects sitting on a flower
• objects that are placed somewhere in a fixed position

So even though English speakers may not naturally say the bee sits on the flower, Norwegian does.

På means on here.

It is the normal preposition for something resting on a surface:

• på bordet = on the table
• på veggen = on the wall
• på blomsten = on the flower

So Bien sitter på blomsten literally has the structure The bee sits on the flower.

The sentence follows a very common Norwegian pattern:

Subject + verb + prepositional phrase

• Bien = subject
• sitter = verb
• på blomsten = prepositional phrase

So the structure is:

Bien sitter på blomsten.
The bee sits/is sitting on the flower.

This sentence looks very similar to English word order, which makes it a nice beginner sentence.

You would use the indefinite forms:

En bi sitter på en blomst.

Compare:

• Bien sitter på blomsten. = The bee is sitting on the flower.
• En bi sitter på en blomst. = A bee is sitting on a flower.

So the change is:

• bien → en bi
• blomsten → en blomst

A rough pronunciation guide for an English speaker is:

• Bien ≈ BEE-en
• sitter ≈ SIT-ter
• på ≈ paw (but with a pure vowel)
• blomsten ≈ BLOM-sten

A few helpful notes:

• Bien has two syllables.
• sitter has a short i, like in sit.
• å in på is a rounded vowel somewhat like the vowel in British law or caught.
• blomsten has the consonant cluster mst, which may take some practice.

Yes, Bien sitter på blomsten is standard Bokmål.

A learner will most often meet this kind of sentence in Bokmål materials. The spelling and structure are completely normal and natural in that written standard.
