Den nåværende planen fungerer.

Because planen is a definite noun: planen means the plan.

In Norwegian, when you add an adjective before a definite noun, you usually need:

• a definite article before the adjective: den
• the noun itself in its definite form: planen

So:

• planen = the plan
• den nåværende planen = the current plan

This is a very common pattern in Norwegian:

• den store bilen = the big car
• det gamle huset = the old house
• de nye bøkene = the new books

Because plan is a common gender noun in Norwegian.

Norwegian nouns can be:

• common gender (often using en in the indefinite form)
• neuter (using et)

Since it is:

• en plan = a plan

the correct definite article before the adjective is:

• den nåværende planen

If it were a neuter noun, you would use det instead:

• det nye huset = the new house

Because adjectives usually take the -e form when they come before a definite noun.

Here the noun phrase is definite:

• den ... planen = the ... plan

So the adjective becomes:

• nåværende

This is the normal pattern:

• en stor bil = a big car
• den store bilen = the big car

Even though nåværende already ends in -e, it is still the form used in this definite structure.

Nåværende means current, present, or existing at the moment.

It is a somewhat formal or neutral word. In many contexts, it fits well in writing, news, official language, and careful speech.

Examples:

• nåværende leder = current leader
• nåværende situasjon = current situation
• nåværende planen is not correct by itself, but den nåværende planen is correct.

A related, simpler everyday idea is current/right now, but the best exact English match depends on context.

Sometimes, yes, but not always.

aktuell in Norwegian often means:

• relevant
• the one being discussed
• sometimes current, depending on context

So:

• den aktuelle planen can mean the plan in question or the relevant plan
• den nåværende planen more clearly means the current plan

A learner should be careful, because aktuell does not always match English actual.

Because planen is the definite form of plan.

• en plan = a plan
• planen = the plan

In this sentence, the noun phrase is definite, so Norwegian uses the definite ending:

• den nåværende planen

Using just den nåværende plan sounds old-fashioned, literary, or Danish-like to many learners. In standard modern Norwegian, den nåværende planen is the normal form.

Fungerer is present tense.

The infinitive is:

• å fungere = to function / to work

The present tense is formed very regularly:

• fungerer = functions / works

Examples:

• Planen fungerer. = The plan works.
• Systemet fungerer. = The system works.

Norwegian present tense does not change for different persons:

• jeg fungerer
• du fungerer
• den fungerer
• vi fungerer

So the verb form stays the same.

It can mean both.

In a sentence like Den nåværende planen fungerer, the natural English meaning is usually:

• The current plan works

But more literally, fungerer means:

• functions
• is functioning
• works

Norwegian often uses fungere where English would casually use work:

• Det fungerer. = It works.
• Planen fungerer bra. = The plan works well.

Because this is a basic main clause with:

• subject: Den nåværende planen
• verb: fungerer

So the pattern is simply:

Subject + verb

That is very common in Norwegian:

• Bilen stopper. = The car stops.
• Den nye løsningen fungerer. = The new solution works.

If another element came first, Norwegian would usually move the verb into second position:

• Nå fungerer den nåværende planen. = Now the current plan works.

That is the normal V2 word order of Norwegian main clauses.

Yes. That means The plan works.

The longer version:

• Den nåværende planen fungerer

adds the idea that it is the current plan, perhaps in contrast with:

• an older plan
• a new plan
• an alternative plan

So:

• Planen fungerer = more general
• Den nåværende planen fungerer = specifically the current plan works

A rough learner-friendly guide is:

• nå sounds roughly like no but with a different Norwegian vowel
• vær has the æ sound, somewhat like the vowel in English cat, but not exactly
• ende is pronounced more lightly at the end

A very rough approximation might be:

NOH-vair-en-deh

But that is only approximate. The tricky parts are:

• å
• æ
• the Norwegian r

If you want to sound more natural, it helps to listen carefully to native audio, because this word contains several sounds that do not match English exactly.
