Bildestabiliseringen fungerer godt.

Because Norwegian, like German and unlike English, very often makes compound nouns by writing them as one word.

So:

• bilde = image / picture
• stabilisering = stabilization

Together:

• bildestabilisering = image stabilization

Then Norwegian adds the definite ending to the whole noun:

• bildestabiliseringen = the image stabilization

A useful rule is that Norwegian usually does not write this as separate words the way English does.

The ending -en marks the noun as definite singular.

Here the base noun is:

• en bildestabilisering = an image stabilization / image stabilization

And the definite form is:

• bildestabiliseringen = the image stabilization

In Norwegian, definiteness is often shown by adding an ending to the noun instead of putting a separate word like the in front.

In Norwegian compounds, the last part usually decides the grammatical gender.

Here the last part is:

• stabilisering

This is a masculine noun in Bokmål:

• en stabilisering

So the full compound is also masculine:

• en bildestabilisering
• bildestabiliseringen

This is a very useful pattern for understanding long compound nouns.

Fungerer is the present tense of å fungere = to function / to work.

So:

• å fungere = to function
• fungerer = functions / is working / works

In this sentence, it means something like works or functions.

A lot of Norwegian verbs in the present tense end in -r:

• snakker = speaks / is speaking
• liker = likes
• fungerer = works / functions

Because godt is being used as an adverb, modifying the verb fungerer.

Compare:

• en god kameraapp = a good camera app

  • here god describes a noun, so it is an adjective

• kameraappen fungerer godt = the camera app works well

  • here godt describes how it works, so it functions as an adverb

In Norwegian, the adverb form is often the same as the neuter singular form of the adjective:

• god → godt

So:

• fungerer godt = works well

Yes. Fungerer bra is very common and natural.

Both are fine:

• fungerer godt
• fungerer bra

Very roughly:

• bra is extremely common in everyday speech
• godt can sound a bit more formal, careful, or written, depending on context

But both are normal Norwegian.

The sentence has the normal main-clause order:

• Bildestabiliseringen = subject
• fungerer = finite verb
• godt = adverb

So the pattern is:

• Subject + verb + adverb

This is also consistent with the Norwegian V2 rule: in main clauses, the finite verb is typically in the second position.

Since the subject comes first here, the verb naturally comes right after it.

Yes. English says:

• the image stabilization

Norwegian usually expresses this with a suffix:

• bildestabiliseringen

So instead of a separate word like the, Norwegian often attaches definiteness directly to the noun.

That is one of the biggest structural differences English speakers notice.

It would be:

• Bildestabilisering fungerer godt.

But that is less natural in most ordinary contexts if you mean a specific image stabilization system.

More commonly, you would say:

• Bildestabiliseringen fungerer godt. = The image stabilization works well.

The definite form is natural when talking about a particular camera, phone, or device feature already being discussed.

A rough English-friendly approximation is:

• BIL-deh-stah-bih-lih-seh-RING-en fung-GEH-rer got

A few notes:

• bildestabiliseringen has the main stress toward -ring-
• fungerer is usually pronounced with a clear ng sound
• godt is pronounced more like gott than like English goat

Pronunciation varies somewhat by dialect, but this approximation is close enough to help you recognize it.

Yes, especially in contexts like cameras, phones, lenses, and video equipment.

It is a technical or product-related word, but very normal in that context. Norwegian often forms such technical terms as compounds, so once you get used to them, they become much easier to read:

• bildestabilisering = image stabilization
• autofokus = autofocus
• bildekvalitet = image quality

So even if the word looks long, its structure is very typical Norwegian.
