Öryggið er mikilvægt.

-ið is the suffixed definite article. Icelandic usually attaches the to the end of the noun instead of putting it in front.

So:

• öryggi = safety / security
• öryggið = the safety / the security

This is very common in Icelandic:

• hús = house
• húsið = the house

Because Icelandic normally expresses the by attaching it to the noun.

So instead of something like English the safety, Icelandic uses one word: öryggið.

This is one of the first big differences English speakers notice:

• English: the book
• Icelandic: bókin (book-the)

Because the adjective has to agree with the noun it describes.

Öryggi is a neuter singular noun, so the adjective must also be neuter singular.

The adjective’s dictionary form is mikilvægur (important), but its forms change:

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

Since öryggið is neuter, Icelandic uses mikilvægt.

The dictionary form is mikilvægur.

When you look up Icelandic adjectives, you usually find them in the masculine singular nominative form. So even though the sentence has mikilvægt, the form you would look up is mikilvægur.

Because mikilvægur is the masculine form, and öryggið is neuter.

Icelandic adjectives change for:

• gender
• number
• case

Here the subject is neuter singular, so the correct form is mikilvægt.

It is functioning as the subject of the sentence, so it is in the nominative case.

The sentence pattern is:

• Öryggið = subject
• er = verb
• mikilvægt = predicate adjective

One small detail: with this noun, the nominative and accusative singular forms happen to look the same, but in this sentence the role is clearly nominative because it is the subject.

Because mikilvægt is a predicate adjective, not an adjective directly placed before a noun.

In Öryggið er mikilvægt, the structure is:

• The safety
• is
• important

Here mikilvægt comes after er and describes the subject. In this position, Icelandic does not add the definite article to the adjective. The adjective just agrees with the subject.

Yes. Er is the present singular form of að vera (to be).

So:

• að vera = to be
• er = is

In this sentence, er means is.

No, this is the most basic and natural word order:

• subject + verb + complement

So:

• Öryggið = subject
• er = verb
• mikilvægt = complement

That makes the sentence very straightforward for learners.

Yes. That would also be a natural sentence, but the nuance is a little different.

• Öryggi er mikilvægt = Safety is important in a general sense
• Öryggið er mikilvægt = The safety is important / the safety matters, often referring to a specific safety issue or a context already understood

So the version with -ið is more definite and context-based.

A few helpful pronunciation points:

• ö sounds something like German ö
• y in modern Icelandic is pronounced the same as i
• final ð is like th in this, though often very light

So the spelling may look difficult, but the main thing to remember is that y does not sound like English y.

The trickiest part for many learners is æ, which is pronounced roughly like eye in English.

So in mikilvægt:

• æ is not like English a
• the word does not sound the way an English speaker might guess from the spelling

Also, consonant combinations in Icelandic often sound softer or different from what English spelling habits would suggest, so it is best to learn this word as a whole rather than letter by letter.

It can mean both, depending on context.

That is very common in Icelandic: one word can cover a range that English splits into two words.

So öryggi may refer to:

• safety
• security
• sometimes a broader sense of protection or being safe/secure

The exact meaning depends on the situation.
