Holdbarheten kommer an på oppbevaringstemperaturen.

Holdbarheten is the definite form of holdbarhet, which means shelf life, durability, or how long something keeps depending on context.

• holdbarhet = shelf life / durability
• holdbarheten = the shelf life

In Norwegian, the definite article is usually added to the end of the noun instead of being a separate word in front, so:

• en holdbarhet = a shelf life
• holdbarheten = the shelf life

That is why Norwegian does not need a separate word like the here.

Å komme an på is a fixed expression meaning to depend on.

In the sentence:

• Holdbarheten kommer an på oppbevaringstemperaturen.

the verb is split because Norwegian often separates parts of certain verb expressions in main clauses.

You can think of it as:

• å komme an på noe = to depend on something

In the infinitive, it stays together:

• Det ser ut til å komme an på temperaturen.
  • It seems to depend on the temperature.

In a normal main clause, the finite verb comes early, and the rest stays later:

• Det kommer an på temperaturen.
  • It depends on the temperature.

So kommer is the conjugated verb, while an på stays later in the clause.

Not completely. It behaves like a fixed verbal expression, a bit like a phrasal verb in English.

Important points:

• å komme an på = to depend on
• It normally takes på + noun/pronoun
• The meaning cannot be guessed just from komme alone, because komme usually means come

Examples:

• Det kommer an på været. = It depends on the weather.
• Alt kommer an på deg. = Everything depends on you.

So when learning it, it is best to memorize komme an på as one unit.

Because the fixed expression is å komme an på noe.

So the preposition på is required by the expression itself. It is not chosen freely here.

• komme an på temperaturen = depend on the temperature
• komme an på kvaliteten = depend on the quality

A learner should treat an på as part of the meaning depend on.

Oppbevaringstemperaturen is a compound noun, which is very common in Norwegian.

It is made up of:

• oppbevaring = storage
• temperatur = temperature
• -en = the definite ending

So:

• oppbevaringstemperatur = storage temperature
• oppbevaringstemperaturen = the storage temperature

Norwegian often combines nouns into one long word where English would often use two separate words.

More examples:

• bokhylle = bookshelf
• sommerferie = summer holiday
• arbeidsdag = workday

Because Norwegian often uses the definite form where English also uses the, especially when talking about a specific concept in a general factual statement.

So this sentence is talking about:

• the shelf life
• the storage temperature

This sounds natural in Norwegian when making a general statement about how one thing is determined by another.

If you made it indefinite, the meaning would change slightly or sound less natural in this context:

• En holdbarhet kommer an på en oppbevaringstemperatur
  This sounds odd and unnatural.

The definite forms are the normal choice here.

Norwegian main clauses usually follow the V2 rule, which means the finite verb comes in the second position.

Here the structure is:

1. Holdbarheten
2. kommer
3. an på oppbevaringstemperaturen

So the verb kommer must come right after the first element.

This is very normal Norwegian word order.

Compare:

• Holdbarheten kommer an på oppbevaringstemperaturen.
• I praksis kommer holdbarheten an på oppbevaringstemperaturen.

In the second sentence, I praksis is the first element, so kommer still stays second.

Yes. Å avhenge av also means to depend on.

So you could say:

• Holdbarheten avhenger av oppbevaringstemperaturen.

This is very close in meaning to:

• Holdbarheten kommer an på oppbevaringstemperaturen.

A small difference in feel:

• kommer an på is very common and natural in everyday language
• avhenger av can sound a bit more formal or technical, though it is also very common

Both are correct.

No. Holdbarhet can mean different but related things depending on context.

Common uses include:

• shelf life for food or medicine
• durability for products or materials
• lasting power in some broader contexts

So in this sentence, if the context is food, holdbarheten most likely means the shelf life. But the word itself is broader than that.

You could say:

• Holdbarhetene kommer an på oppbevaringstemperaturene.

That means the shelf lives depend on the storage temperatures.

But this is less common unless you are comparing several products or several storage conditions.

Singular is much more natural for a general statement:

• Holdbarheten kommer an på oppbevaringstemperaturen.

A rough pronunciation guide is:

• holdbarheten ≈ HOLD-baar-hay-ten
• kommer an på ≈ KOM-er an paw
• oppbevaringstemperaturen ≈ OP-beh-var-ingstem-peh-rah-TOO-ren

A few helpful notes:

• å sounds like the vowel in British law or more
• the r is pronounced, though the exact sound varies by dialect
• compound words usually keep clear stress patterns, often with stronger stress near the beginning

The exact pronunciation can vary by dialect, but the spelling is fairly consistent.

Not very naturally.

A word-for-word breakdown would be something like:

• Holdbarheten = the shelf life
• kommer an på = comes on/upon = depends on
• oppbevaringstemperaturen = the storage temperature

But in natural English, you would not say comes on/upon here. You would simply say depends on.

So this is a good example of why fixed expressions like komme an på should be learned as whole units rather than translated word by word.
