Betjeningsevnen er god.

Because Norwegian usually writes compound nouns as one word.

So:

• betjening = service / operation / servicing
• evne = ability / capacity

Together, betjeningsevne becomes a single noun meaning something like servicing ability/capacity.

This is very normal in Norwegian. English often uses two words or a phrase, but Norwegian prefers compounds:

• språk
  • kurs → språkkurs
• arbeid
  • tid → arbeidstid

So betjeningsevnen is not unusually long by Norwegian standards.

The base form is betjeningsevne.

In the sentence, it appears in the definite singular form:

• betjeningsevne = servicing ability/capacity
• betjeningsevnen = the servicing ability/capacity

The ending -n is what marks it as definite here.

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

So:

• en betjeningsevne = a servicing ability
• betjeningsevnen = the servicing ability

This is one of the most important differences from English. In this sentence, the is built into betjeningsevnen.

It usually means the speaker is referring to a specific, known ability or capacity, not just the concept in general.

Compare:

• Betjeningsevne er viktig. = Servicing capacity is important.
  (general idea)
• Betjeningsevnen er god. = The servicing capacity is good.
  (a specific case is being evaluated)

So the definite form makes it sound like an assessment of a particular company, person, account, loan situation, system, etc., depending on context.

Er is the present tense of the verb å være (to be).

So:

• å være = to be
• er = is / are / am

In this sentence, er links the subject betjeningsevnen with the description god.

Because god has to agree with the noun.

Here, betjeningsevne is not a neuter noun, so the predicate adjective is god.

A useful quick pattern is:

• common gender singular: god
• neuter singular: godt
• plural: gode

So:

• Evnen er god.
• Huset er godt. (different noun type: neuter)
• Resultatene er gode.

Even if a noun can be treated as feminine in some contexts, the adjective here still appears as god, not godt.

In compounds, the last element usually decides the gender. Here the last element is evne.

So since the head noun is evne, the whole compound betjeningsevne follows that noun’s gender pattern.

That is a very helpful rule in Norwegian compound nouns:

• skolebok is a kind of bok
• sommerhus is a kind of hus
• betjeningsevne is a kind of evne

Yes, bra is possible, but god is often a bit more natural in formal assessment-style language.

Very roughly:

• god = good, often used for quality, condition, suitability, evaluation
• bra = good/fine, often a bit more general or conversational

So:

• Betjeningsevnen er god. sounds more formal, technical, or written.
• Betjeningsevnen er bra. is understandable, but may sound a little less formal.

Not usually. It sounds fairly formal or specialized.

You are more likely to see it in contexts like:

• finance
• administration
• business reports
• technical evaluations

A native speaker would probably not use betjeningsevne very often in casual conversation unless the topic was specifically about loans, operations, systems, or some kind of capacity assessment.

A rough guide is:

be-TYE-ning-sev-nen

A few helpful points:

• j in Norwegian sounds like English y
• tj in betjening is not pronounced like English ch here; it blends into a ty/y-like sound
• the stress is typically strongest early in the word, around -tje-

You do not need to pronounce every part very heavily. In natural speech, long compounds often flow together smoothly.

It is the standard Norwegian pattern:

Subject + verb + adjective/complement

• Betjeningsevnen = subject
• er = verb
• god = subject complement / predicate adjective

So it works very much like English The servicing capacity is good.

More or less, yes:

• Betjeningsevnen = the servicing capacity/ability
• er = is
• god = good

But in natural English, the best translation may depend on context. A very literal translation can sound slightly awkward in English, while the Norwegian sentence itself sounds normal in a formal register. So even if the grammar matches closely, the most natural English wording may vary.
