Min nabo er rar.

Min means my.

Danish possessives change depending on the gender and number of the noun:

• min = for a singular common gender noun
• mit = for a singular neuter noun
• mine = for plural nouns

Nabo is a common gender singular noun, so min nabo is correct.

Examples:

• min nabo = my neighbor
• mit hus = my house
• mine venner = my friends

Because in Danish, a possessive like min normally replaces the article.

So you say:

• min nabo = my neighbor

not something like min en nabo or min naboen.

This works much like English, where we say my neighbor, not my the neighbor.

No. Nabo can refer to a neighbor of any gender.

The noun itself is grammatically a common gender noun, but that grammatical gender does not mean the person must be male.

So min nabo can mean:

• my male neighbor
• my female neighbor

If needed, Danish can specify gender in other ways, but nabo by itself is neutral in meaning.

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
• min nabo er = my neighbor is

A useful thing for English speakers: Danish verbs do not change form depending on the subject the way English does. The form er stays the same across persons in the present tense.

Rar usually means nice, kind, pleasant, or sweet when talking about a person.

So Min nabo er rar means something like:

• My neighbor is nice.
• My neighbor is kind.
• My neighbor is pleasant.

The exact best translation depends on context, but the general idea is positive and friendly.

No — this is a very important false friend.

Danish rar does not mean rare in the English sense of uncommon.

Instead, Danish rar means:

• nice
• kind
• pleasant

If you want to say rare/uncommon in Danish, you would usually use a different word, such as sjælden.

So:

• rar person = nice person
• sjælden fejl = rare mistake

Because here rar is a predicate adjective: it describes the subject through the verb er.

The structure is:

• Min nabo = subject
• er = linking verb
• rar = adjective describing the subject

This is the same basic pattern as in English:

• My neighbor is nice.

You can also put the adjective before the noun, but then the form changes:

• min rare nabo = my nice neighbor

So compare:

• Min nabo er rar. = My neighbor is nice.
• Min rare nabo ... = My nice neighbor ...

Because adjectives in Danish can change form depending on how they are used.

In this sentence, rar is describing a singular common gender subject: nabo. So the basic form rar is used.

Common patterns are:

• en rar nabo = a nice neighbor
• et rart sted = a nice place
• rare naboer = nice neighbors

And with a possessive + adjective before the noun:

• min rare nabo = my nice neighbor

So in Min nabo er rar, rar is the correct form.

The word order is the standard Danish main-clause pattern:

• Subject + verb + complement

So:

• Min nabo = subject
• er = verb
• rar = complement

That is why the sentence looks very straightforward to an English speaker:

• My neighbor is nice.

Danish word order becomes more interesting in other sentence types, but this sentence is a simple declarative sentence.

Yes.

The negative version is:

• Min nabo er ikke rar. = My neighbor is not nice.

In a simple main clause, ikke usually comes after the finite verb and often after short predicate structures like this.

So:

• Han er rar. = He is nice.
• Han er ikke rar. = He is not nice.
