Rådgiveren hjelper dem når det gjelder aktivitetskravet og pleiepengene.

Because rådgiveren means the adviser/counsellor, not an adviser.

In Norwegian, definiteness is usually shown by adding an ending to the noun:

• en rådgiver = an adviser
• rådgiveren = the adviser

Here, the sentence is talking about a specific adviser, so the definite form is used.

Dem means them.

It is the object form of the pronoun, used because it receives the action of the verb:

• Rådgiveren hjelper dem = The adviser helps them

Compare:

• de = they (subject form)
• dem = them (object form)

So de hjelper = they help, but hjelper dem = helps them.

Not really. Although når often means when, the whole expression når det gjelder is a very common phrase meaning:

• when it comes to
• regarding
• as for
• in matters concerning

So here it is best understood as a fixed expression, not as a literal time clause.

Breaking it down:

• når = when
• det = it
• gjelder = concerns / applies to

Literally, it is something like when it concerns, but in natural English that becomes when it comes to or regarding.

The det is a kind of dummy subject. Norwegian often needs an explicit subject where English might not think about it much.

In det gjelder, the word det does not refer to a specific thing in a strong, concrete way. It is just part of the normal structure of the expression.

So learners should mainly memorize når det gjelder as a set phrase.

Aktivitetskravet is a compound noun in the definite singular.

It is built from:

• aktivitet = activity
• krav = requirement
• aktivitetskrav = activity requirement
• aktivitetskravet = the activity requirement

A few things to notice:

1. Norwegian very often combines nouns into one word.
2. The -s- in the middle is a common linking element in compounds.
3. The ending -et shows definite singular for a neuter noun.

So aktivitetskravet means the activity requirement.

Because pleiepenger is normally used as a plural-style noun.

This word refers to a type of benefit/payment, and many Norwegian words connected with money or benefits are built with -penger.

So:

• pleiepenger = care benefit / attendance benefit / care-related payment
• pleiepengene = the care benefit(s)

The ending -ne marks the definite plural.

Even if English may translate it with a singular-looking expression like the care benefit, Norwegian uses the plural form penger.

Because Norwegian usually puts the meaning at the end of the noun instead of using a separate word.

Examples:

• krav = requirement
• kravet = the requirement
• penger = money / payments
• pengene = the money / the payments

So:

• aktivitetskravet already means the activity requirement
• pleiepengene already means the care benefit/payments

That is why you do not add a separate word like English the.

Hjelper is the present tense of å hjelpe = to help.

Norwegian verbs do not change according to the subject the way English verbs sometimes do. The same present-tense form is used with all persons:

• jeg hjelper = I help
• du hjelper = you help
• han/hun hjelper = he/she helps
• vi hjelper = we help

So Rådgiveren hjelper dem simply means The adviser helps them.

Yes. It is normal.

Inside the expression, the order is:

• det = subject
• gjelder = verb
• aktivitetskravet og pleiepengene = what it concerns

So the structure is straightforward: subject + verb + object/complement

Also, because når det gjelder functions almost like a fixed phrase, learners usually do best by recognizing it as one chunk.

Because Norwegian, like English, can coordinate two noun phrases directly with og = and.

So:

• aktivitetskravet og pleiepengene = the activity requirement and the care benefit

There is no need to repeat anything before the second noun unless you want extra emphasis or a different structure.

Yes. Depending on style, you might also see expressions like:

• om = about
• angående = regarding
• i forbindelse med = in connection with

But når det gjelder is very common and natural, especially in formal or administrative contexts. It works well when introducing the topic someone is helping with.
