Huset er i god tilstand.

Because -et is the definite ending for many neuter nouns in Danish.

• et hus = a house
• huset = the house

Unlike English, Danish often puts the at the end of the noun instead of using a separate word.

Hus is a neuter noun in Danish, so its article is et.

Its basic forms are:

• et hus = a house
• huset = the house
• huse = houses
• husene = the houses

This matters because Danish articles and adjective forms often depend on whether a noun is common gender or neuter.

Er is the present tense of at være = to be.

So:

• huset er = the house is

In this sentence, er links the subject (huset) with a description of its condition (i god tilstand).

Tilstand means condition, state, or overall state of repair/quality, depending on context.

In i god tilstand, it means something like:

• in good condition
• in a good state

It is a very natural word when talking about how well something is maintained.

Because god describes tilstand, not huset.

Here, tilstand is a common-gender singular noun, so the adjective takes the common singular indefinite form:

• en god tilstand = a good condition/state

Compare:

• et godt hus = a good house
  Here godt matches hus, which is neuter.
• en god tilstand = a good condition
  Here god matches tilstand, which is common gender.

So even though huset is neuter, that does not control the adjective here.

Because Danish often omits the article in set expressions after prepositions, especially in phrases like this.

So:

• i god tilstand = in good condition

This is the normal, idiomatic way to say it.

You can sometimes hear or read i en god tilstand, but that sounds less natural here and more specific or less idiomatic. The standard phrase is i god tilstand.

Because Danish uses i in this fixed expression:

• i god tilstand = in good condition

It works much like English in in in good condition.

You should think of this as a phrase worth learning as a whole, rather than translating each word independently every time.

Yes, but it means something different.

• Huset er i god tilstand = The house is in good condition
• Huset er godt = The house is good

The second sentence is much broader and less specific. It could mean the house is good overall, but it does not specifically focus on its physical condition or state of repair.

Yes, very much so.

It is a common Danish way to talk about the condition of objects, buildings, machines, furniture, and similar things.

You can also change the adjective:

• i dårlig tilstand = in bad condition
• i fin tilstand = in fine/good condition
• i perfekt tilstand = in perfect condition

So the pattern is very useful: [noun] + er + i + adjective + tilstand

The word order is straightforward:

• Huset = subject
• er = verb
• i god tilstand = prepositional phrase describing the subject

So the structure is:

Subject + verb + description

This is normal Danish main-clause word order.

If you mean the houses are in good condition, you would say:

• Husene er i god tilstand.

Notice that i god tilstand stays the same here, because god still belongs to tilstand, and tilstand is still singular in the expression.

A careful approximate pronunciation is:

HOO-set air ee go til-stan

A few helpful notes:

• huset: the u is not exactly like English oo, but that approximation helps.
• er often sounds short and unstressed in normal speech.
• god in Danish is not pronounced exactly like English good.
• tilstand has the main stress on the second part: -stand.

In natural speech, Danish pronunciation is often softer and more reduced than the spelling suggests.

Yes.

It can refer to:

• physical condition: a house, car, phone, furniture
• general state: a system, situation, or even a person in some contexts

But in Huset er i god tilstand, the meaning is clearly the house’s physical condition.
