Sluttstykket sitter ved dørbladet.

Because both nouns are in the definite singular form, and both are neuter nouns.

• et sluttstykke → sluttstykket
• et dørblad → dørbladet

In Norwegian, the definite article is usually attached to the end of the noun instead of being a separate word like English the.

So:

• sluttstykket = the strike plate / the latch plate
• dørbladet = the door leaf / the door panel

Not literally, no. In Norwegian, å sitte is often used for the position of things, not just people.

Here, sitter means something like:

• is located
• is positioned
• is attached
• is fitted

So in this sentence, it suggests that the sluttstykke is physically placed or mounted by the door leaf.

This is very natural in Norwegian. English usually uses is, is located, or is attached, where Norwegian often prefers a positional verb like sitter, står, or ligger.

Using sitter gives a more specific picture than er.

• er = simply is
• sitter = is sitting/positioned/fixed in place

For an object such as a piece of hardware, sitter often implies that it is mounted or installed somewhere.

So:

• Sluttstykket er ved dørbladet = more neutral, just says it is there
• Sluttstykket sitter ved dørbladet = suggests it is physically fitted or placed there

Ved usually means by, near, beside, or sometimes at.

In this sentence, it means that the sluttstykket is located by / next to the door leaf.

It does not necessarily mean direct contact in the same way that på often does.

Compare:

• ved dørbladet = by / next to the door leaf
• på dørbladet = on the door leaf

So ved focuses more on location relative to the door leaf.

Dørbladet is a technical word meaning the door leaf: the moving part of the door itself, as opposed to the frame.

It is a compound noun:

• dør = door
• blad = leaf / panel

So dørblad literally means door leaf.

In everyday English, depending on context, you might think of it as the door panel or simply the door itself, but technically it means the swinging/sliding part, not the frame.

Yes. Norwegian uses compound nouns very often, and they are usually written as one word.

• sluttstykke = slutt
  • stykke
• dørblad = dør
  • blad

A useful rule is that the last part of the compound is the main noun. It determines things like gender and inflection.

For example:

• stykke is neuter, so sluttstykke is neuter
• blad is neuter, so dørblad is neuter

That is why both take definite -et.

The sentence has normal main-clause word order:

• Sluttstykket = subject
• sitter = verb
• ved dørbladet = prepositional phrase

So it is simply:

Subject + Verb + Adverbial

This follows the usual Norwegian V2 pattern, where the finite verb comes in the second position in a main clause.

Because the subject comes first here, the order looks straightforward. But if another element came first, the verb would still stay in second position:

• Ved dørbladet sitter sluttstykket.

That is also grammatical, though more marked.

Because Norwegian usually puts the definite article on the end of the noun.

So instead of:

• the door leaf
• the strike plate

Norwegian says:

• dørbladet
• sluttstykket

This is one of the biggest structural differences from English. In many simple cases, English the becomes a suffix in Norwegian.

It sounds fairly technical, mainly because of the nouns sluttstykket and dørbladet.

A native speaker outside a technical context might be more likely to use less specialized wording, depending on what exactly is meant. But in construction, locksmithing, architecture, or hardware descriptions, this kind of sentence is very natural.

So the grammar is ordinary, but the vocabulary is specialized.
