Tjenesten er god.

Because -en is the usual definite singular ending for many common-gender Danish nouns.

• en tjeneste = a service / a favor
• tjenesten = the service / the favor

So in this sentence, tjenesten is not just service in general; it means the service, referring to a specific service already known from the context.

The base form is tjeneste.

Its forms are:

• en tjeneste = a service / a favor
• tjenesten = the service / the favor
• tjenester = services / favors
• tjenesterne = the services / the favors

So tjenesten is simply tjeneste with the definite ending -en.

In Danish, the definite article is often attached to the end of the noun instead of being a separate word.

So instead of saying something like English the service, Danish usually says:

• tjenesten

This is very normal in Danish. English puts the before the noun; Danish often adds the definiteness to the noun itself.

Because tjeneste is a common-gender singular noun, and the adjective must agree with it.

For predicate adjectives after er, the usual pattern is:

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

So:

• Tjenesten er god. = The service is good.
• Huset er godt. = The house is good.
• Tjenesterne er gode. = The services are good.

Since tjenesten is common gender singular, god is the correct form.

Er is the present tense of at være, which means to be.

So:

• jeg er = I am
• du er = you are
• han/hun er = he/she is
• tjenesten er = the service is

In this sentence, er simply means is.

Yes, in this basic sentence it is very similar to English:

• Tjenesten = subject
• er = verb
• god = adjective / subject complement

So the structure is:

• Subject + verb + adjective

This is one reason the sentence feels quite approachable for English speakers.

A rough guide is:

• tjenesten ≈ TYE-ne-sten
• er ≈ a very short air / uh sound, depending on accent
• god ≈ gohth or goh, with a soft final consonant in many pronunciations

A few helpful points:

• tj in Danish often sounds a bit like ty in tune for many English speakers.
• Unstressed -en is often reduced, so it may sound lighter than you expect.
• Danish pronunciation is often less fully pronounced than spelling suggests.

If you want a practical learner approach, saying something close to TYE-ne-sten air goh is a decent start.

No. Tjeneste can have a few related meanings depending on context, such as:

• service
• favor
• duty
• service/employment in some formal or older contexts

In Tjenesten er god, the most natural meaning is usually the service is good, but in another context it could mean something else. Danish words often cover a wider range than a single English translation.

Because after er, the adjective is a predicate adjective, and predicate adjectives are not made definite in the same way.

Compare:

• den gode tjeneste = the good service
  Here gode comes before the noun, so it follows the definite pattern.

But:

• tjenesten er god = the service is good
  Here god comes after er, so it stays in the predicate form that agrees only in gender/number.

This is a very common Danish pattern.

You usually add ikke after the verb:

• Tjenesten er ikke god. = The service is not good.

That placement is very normal in Danish main clauses:

• subject + verb + ikke
  • adjective/complement

In a yes/no question, Danish usually puts the verb before the subject:

• Er tjenesten god? = Is the service good?

So the statement:

• Tjenesten er god.

becomes:

• Er tjenesten god?

This verb-first pattern is very important in Danish questions.

Yes, often you can. Service is also a very common word in Danish, especially in modern everyday language.

So these can both occur:

• Tjenesten er god.
• Servicen er god.

The difference depends on context and style:

• service/servicen often refers to customer service or the quality of service
• tjeneste/tjenesten can sound broader and can also mean favor or duty in other contexts

So servicen may sound more natural in some modern customer-service situations, while tjenesten is still perfectly understandable and correct.
