Dekningen gjelder for forsikringstakeren hele året.

Because Norwegian usually expresses the by attaching the definite ending to the noun.

• dekning = coverage
• dekningen = the coverage

So dekningen is the singular definite form.

This is a very common pattern in Norwegian:

• bil → bilen = the car
• forsikring → forsikringen = the insurance
• dekning → dekningen = the coverage

In this sentence, the speaker is referring to a specific coverage already known from the context, so the definite form is natural.

Gjelder is the present tense of å gjelde.

In this kind of sentence, it often means:

• to apply
• to be valid
• to concern

So Dekningen gjelder ... means something like:

• The coverage applies ...
• The coverage is valid ...

This verb is very common in formal, legal, and insurance-related language.

Examples:

• Regelen gjelder alle. = The rule applies to everyone.
• Tilbudet gjelder ut måneden. = The offer is valid until the end of the month.

Because gjelde can be used in more than one way.

In many cases, especially in formal or practical language, gjelde for means to apply to / be valid for someone or something.

So:

• gjelder for forsikringstakeren = applies to the policyholder

Without for, gjelde can also mean concern or affect more directly:

• Dette gjelder deg. = This concerns you / This applies to you.

In real usage, both patterns exist, but gjelde for is especially common when talking about rules, coverage, validity, and conditions.

It is a compound noun, which is extremely common in Norwegian.

It is made up of:

• forsikring = insurance
• taker = taker / one who takes or holds something
• forsikringstaker = policyholder
• forsikringstakeren = the policyholder

So the -en at the end again marks the definite form: the policyholder.

Norwegian often builds precise meanings by combining nouns into one word. English often prefers separate words, while Norwegian frequently writes them as a single compound.

Because hele året means the whole year / all year round, where året is in the definite form.

This is a very common Norwegian pattern with time expressions:

• hele dagen = the whole day
• hele uka = the whole week
• hele måneden = the whole month
• hele året = the whole year / all year

The idea is not just a whole year as a duration, but the entire year as a known time period.

Compare:

• hele året = all year / the whole year
• et helt år = a whole year / one full year

So these are not interchangeable.

They are close, but not the same.

• hele året = all year, throughout the year
• et helt år = a whole year, one full year

Examples:

• Butikken er åpen hele året. = The shop is open all year.
• Han bodde der i et helt år. = He lived there for a whole year.

In your sentence, hele året fits because the meaning is that the coverage applies throughout the year.

This is a normal Norwegian main-clause word order:

• Dekningen = subject
• gjelder = verb
• for forsikringstakeren = prepositional phrase
• hele året = time expression

So it follows the basic pattern:

Subject + Verb + other elements

The time expression often comes later in the sentence, especially if it is not being emphasized.

You could move hele året to the front for emphasis, but then Norwegian keeps the verb in second position:

• Hele året gjelder dekningen for forsikringstakeren.

That is grammatically possible, though the original version sounds more neutral.

It is common, but it sounds somewhat formal depending on context.

Dekning can mean things like:

• coverage
• insurance cover
• signal coverage / network coverage
• coverage in a broader practical sense

In insurance language, dekning is very common. In everyday conversation, people also use it, but the exact meaning depends on context.

For example:

• god dekning = good coverage
• mobildekning = mobile signal coverage
• forsikringsdekning = insurance coverage

So in this sentence, it clearly belongs to insurance vocabulary.

Yes. Norwegian often allows a few variations depending on style.

For example:

• Forsikringen gjelder for forsikringstakeren hele året.
• Dekningen gjelder hele året for forsikringstakeren.

These are all understandable, but they are not exactly identical in focus.

The original sentence emphasizes the coverage itself.
A version with forsikringen would emphasize the insurance policy rather than specifically the coverage.

So the original is natural if the text is discussing what the coverage includes and when it is valid.
