Skjermavstanden påvirker sittestillingen.

It is a compound noun:

• skjerm = screen
• avstand = distance
• -en = the definite ending, roughly the

So skjermavstanden means the screen distance, or more naturally in English, the distance to/from the screen.

In Norwegian, the last part of a compound is the main noun. Here, the main noun is avstand, and skjerm- just tells you what kind of distance it is.

Because Norwegian normally writes compound nouns as a single word.

So:

• skjermavstand = correct
• skjerm avstand = wrong

This is much more common in Norwegian than in English. English often uses separate words, but Norwegian strongly prefers one-word compounds for this kind of idea.

The -en is the definite article attached to the noun.

Compare:

• en skjermavstand = a screen distance
• skjermavstanden = the screen distance

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

That is why there is no separate word like English the here.

If you add an adjective, Norwegian usually uses both a separate article and the ending:

• den riktige skjermavstanden = the correct screen distance

Yes. Avstanden til skjermen is a perfectly normal alternative.

The difference is mostly style:

• skjermavstanden = more compact, often more technical
• avstanden til skjermen = more unpacked and explicit

Both can work, and both would be understood. A sentence like Avstanden til skjermen påvirker sittestillingen sounds natural too.

Påvirker is the present tense of å påvirke, which means to affect or to influence.

So:

• å påvirke = to affect
• påvirker = affects / is affecting

Unlike English, Norwegian does not change the verb for different persons:

• jeg påvirker
• du påvirker
• den påvirker
• vi påvirker

The form stays the same.

It is another compound noun:

• sitte = to sit
• stilling = position, posture
• -en = the definite ending

So sittestillingen means the sitting position or the sitting posture.

In context, posture is often the most natural English translation.

Because Norwegian often uses the definite form where English might use a more general noun.

In a sentence like this, Norwegian treats both ideas as known or relevant concepts:

• skjermavstanden = the screen distance
• sittestillingen = the sitting posture

This can sound more natural in Norwegian than a fully indefinite version.

So even if English might say something like screen distance affects posture, Norwegian often prefers the definite forms in ordinary prose.

You could, but it would sound less natural in normal sentence style.

It might work in:

• a headline
• a bullet point
• a chart label
• a very compressed technical style

But in ordinary writing or speech, Skjermavstanden påvirker sittestillingen sounds more natural and complete.

This is the normal main-clause word order:

• Skjermavstanden = subject
• påvirker = verb
• sittestillingen = object

So it follows a straightforward subject–verb–object pattern, much like English.

One important Norwegian rule is that the verb usually stays in second position in main clauses. For example:

• Ofte påvirker skjermavstanden sittestillingen.

Not:

• Ofte skjermavstanden påvirker sittestillingen.

So the basic sentence is simple, but it still follows the usual Norwegian verb-second pattern.
