Questions & Answers about Årsmiddelverdien sammenlignes med tiltaksgrensen.

Is Å at the beginning the infinitive marker å?

No. Here Å is just the letter å, capitalized because it is the first letter of the sentence.

So Årsmiddelverdien is a noun, not an infinitive.
Compare:

• å sammenligne = to compare → here å is the infinitive marker
• Årsmiddelverdien = a noun starting with the letter å

This is a very common thing for learners to notice, because the same written form å can either be:

• the letter å, or
• the infinitive marker å

You tell the difference from context.

Why is årsmiddelverdien written as one long word?

Because Norwegian normally writes compound nouns as one word.

So årsmiddelverdien is built from smaller parts:

• år = year
• middel = average / mean
• verdi = value
• -en = the definite singular ending

Together, the compound means something like the annual average value.

This is very normal in Norwegian. English often uses several separate words, but Norwegian prefers one compound word.

Why does årsmiddelverdien end in -en?
