Langtidsmålingen gir en årsmiddelverdi.

Because Norwegian normally writes compound nouns as one word, much more often than English does.

So:

• langtid = long term / long duration
• måling = measurement

Together, langtidsmåling means long-term measurement.

Then the ending -en is added to make it definite:

• langtidsmåling = a long-term measurement
• langtidsmålingen = the long-term measurement

This is very typical in Norwegian. An English speaker may want to separate it into multiple words, but standard Norwegian spelling keeps it together.

The ending -en is the definite article attached to the noun. In English, you usually put the before the noun; in Norwegian, the definiteness is often added to the end instead.

Compare:

• en måling = a measurement
• målingen = the measurement

So:

• langtidsmåling = long-term measurement
• langtidsmålingen = the long-term measurement

This is one of the biggest structural differences from English.

Gir is the present tense of å gi = to give.

So:

• å gi = to give
• gir = gives / is giving

In this sentence, gir means something like produces, yields, or gives.

The full structure is:

• Langtidsmålingen = the long-term measurement
• gir = gives / yields
• en årsmiddelverdi = an annual mean value

Norwegian present tense is simpler than English in many ways, because the verb form does not change depending on the subject:

• jeg gir
• du gir
• han/hun gir
• vi gir

It is always gir in the present tense.

Because the sentence is talking about an annual mean value, not the annual mean value.

• en årsmiddelverdi = an annual mean value
• årsmiddelverdien = the annual mean value

So the sentence presents the result as one such value, in an indefinite sense.

Also notice the pattern:

• en
  • noun = indefinite singular
• noun + -en = definite singular

For this noun:

• en verdi = a value
• verdien = the value

And in compound form:

• en årsmiddelverdi = an annual mean value
• årsmiddelverdien = the annual mean value

It is another compound noun:

• år = year
• middel = mean / average
• verdi = value

So årsmiddelverdi literally means something like year-mean-value, which in natural English would be annual mean value or yearly average value.

Notice the -s- after år:

• år
  • s
    • middelverdi → årsmiddelverdi

That -s- is a common linking element in Norwegian compounds. It does not usually need to be translated separately; it just helps connect the parts of the word.

Yes. This is a very standard subject–verb–object sentence:

• Langtidsmålingen = subject
• gir = verb
• en årsmiddelverdi = object

So the structure is:

The long-term measurement + gives + an annual mean value

This happens to look very similar to English.

A useful thing to remember, though, is that Norwegian often follows the V2 rule in main clauses, meaning the finite verb usually comes in the second position. In this simple sentence, that gives the same order English would use.

Yes, it matters because gender affects the article and the definite ending.

Here:

• en måling = a measurement
• en verdi = a value

These are common gender nouns, so they use en in the singular indefinite form.

That is why you get:

• en årsmiddelverdi
• langtidsmålingen (with the common-gender definite ending -en)

If a noun were neuter, you would often see et instead of en.

Because Norwegian often puts definiteness on the noun itself instead of using a separate word the way English does.

English:

• the long-term measurement

Norwegian:

• langtidsmålingen

So the idea of the is already built into -en.

This is completely normal. English speakers often look for a separate word corresponding to the, but in Norwegian it is very often a suffix instead.

All of those can work, depending on context.

Literally, gir means gives. But in technical or scientific contexts, English often sounds more natural with:

• yields
• produces
• results in

So although gir is straightforwardly gives, the most natural English translation of the whole sentence may use a different verb. That is a translation choice, not a grammar difference.

A rough guide is:

LANG-tids-MOH-ling-en yeer en OHRS-mid-del-ver-di

A few useful notes:

• Norwegian compounds usually have strong stress early in the word.
• å sounds somewhat like the vowel in British more or thought, depending on accent.
• gi in gir begins with a y-like sound, so gir sounds roughly like yeer.
• The r sound varies by dialect.

If you are learning pronunciation, it helps to practice the compounds in parts first:

• langtid
• måling
• års
• middel
• verdi

Then say them as whole compound nouns.

Yes, but the original sentence is perfectly natural.

Possible alternatives might include things like:

• Langtidsmålingen viser en årsmiddelverdi.
  (shows an annual mean value)

• Langtidsmålingen resulterer i en årsmiddelverdi.
  (results in an annual mean value)

The original with gir is concise and common, especially in technical writing. So if you are wondering whether it sounds natural: yes, it does.

There are three big things:

1. Do not split the compound nouns

   • Write langtidsmålingen, not separate words
   • Write årsmiddelverdi, not separate words

2. Notice how definiteness works

   • -en on langtidsmålingen already means the

3. Do not expect Norwegian verbs to change by person

   • It is just gir in the present tense, regardless of subject

If you keep those three points in mind, this sentence becomes much easier to understand and build from.
