Bótarétturinn er mikilvægur.

In Icelandic, the definite article the is very often attached to the noun as an ending, instead of being a separate word.

So:

• bótaréttur = a/the right to compensation as a dictionary form
• bótarétturinn = the right to compensation

That final -inn is the masculine singular definite article in this form.

This is one of the first big differences from English: Icelandic often says noun + the-ending rather than using a separate word like the.

The base form is bótaréttur.

You can break the sentence word down like this:

• bótaréttur = the noun in its basic dictionary form
• bótarétturinn = that same noun with the definite article added

So if you were looking it up in a dictionary, you would usually search for bótaréttur, not bótarétturinn.

Because Icelandic adjectives must agree with the noun they describe.

Here, bótarétturinn is:

• masculine
• singular
• nominative

So the adjective also has to be:

• masculine
• singular
• nominative

That gives:

• mikilvægur

Compare the different gender forms:

• masculine: mikilvægur
• feminine: mikilvæg
• neuter: mikilvægt

So the ending -ur is there because the subject noun is masculine singular.

Er is the present tense, 3rd person singular form of the verb vera (to be).

So:

• ég er = I am
• þú ert = you are
• hann/hún/það er = he/she/it is

In Bótarétturinn er mikilvægur, the subject is singular, so Icelandic uses er = is.

It is a predicate adjective.

That means it comes after er and describes the subject:

• Bótarétturinn = the subject
• er = is
• mikilvægur = important

This works much like English The right to compensation is important.

Even though it comes after the verb, it still has to agree with the subject in gender, number, and case.

It is in the nominative case.

That is because it is the subject of the sentence, and subjects are usually in the nominative in Icelandic.

You can see this in the adjective too:

• bótarétturinn = nominative singular masculine
• mikilvægur = nominative singular masculine

So both the noun and the adjective match in the nominative.

This is the normal, straightforward word order for a simple statement:

• Subject + verb + complement
• Bótarétturinn + er + mikilvægur

So it matches English fairly closely:

• The right to compensation is important

Icelandic word order can change in other sentence types, especially with adverbs or questions, but this sentence uses the most basic neutral order.

Yes. Icelandic forms many nouns by combining smaller elements into compounds.

Here:

• bóta- relates to compensation/damages
• réttur means right/entitlement

So bótaréttur is a compound meaning something like right to compensation or compensation entitlement.

Compound nouns are extremely common in Icelandic, so getting used to spotting their parts is very helpful.

Yes, réttur can mean different things depending on context.

Common meanings include:

• a right, entitlement
• correct, right as an adjective
• in some contexts, even a dish/course of food

In bótaréttur, it is clearly the noun meaning right or entitlement.

This is very normal in Icelandic: the same word can have several meanings, and the surrounding words tell you which one is intended.

Because Icelandic usually expresses definiteness by attaching the article to the noun.

So instead of:

• separate the
  • noun

Icelandic often uses:

• noun + definite ending

That is why you get:

• bótarétturinn = the right to compensation

There are situations in Icelandic where a separate determiner appears, but in ordinary sentences like this, the attached article is the normal pattern.

Yes. In Icelandic, noun gender is important because it affects:

• adjective endings
• article endings
• pronouns
• some other forms in the sentence

Here, bótaréttur is masculine, which is why you get:

• bótarétturinn
• mikilvægur

If you learned the noun without its gender, it would be much harder to produce correct Icelandic later. A good habit is to learn nouns together with enough information to recognize their gender and pattern.
