Annmarkinn er alvarlegur.

Annmarkinn breaks down as:

• annmarki = a flaw, defect, drawback, shortcoming
• -inn = the definite article, meaning the

So annmarkinn means the flaw or the defect.

Grammatically, it is:

• masculine
• singular
• nominative (the subject form)

In Icelandic, the definite article is very often added to the end of the noun instead of being a separate word.

So:

• annmarki = a flaw
• annmarkinn = the flaw

This is completely normal Icelandic structure. English uses a separate word, but Icelandic often uses a suffix instead.

Er is the present tense singular form of vera, which means to be.

So here it means is.

In this sentence:

• Annmarkinn = the subject
• er = is
• alvarlegur = serious

So the structure is simply:

The flaw is serious.

Because Icelandic adjectives must agree with the noun they describe or refer back to in:

• gender
• number
• case

Here, annmarkinn is:

• masculine
• singular
• nominative

So the adjective also appears in the masculine singular nominative form:

• alvarlegur = serious

If the noun were neuter or feminine, the adjective would look different.

This is a very common question.

After vera (to be), Icelandic normally uses the strong form of the adjective in predicate position.

So:

• Annmarkinn er alvarlegur = The flaw is serious

But when the adjective comes directly before a definite noun, you usually get the weak form:

• alvarlegi annmarkinn = the serious flaw

So the difference is:

• predicate adjective: annmarkinn er alvarlegur
• adjective directly before the noun: alvarlegi annmarkinn

Yes. This is the normal, neutral word order:

• subject
  • verb
    • predicate adjective

So:

• Annmarkinn = subject
• er = verb
• alvarlegur = complement/predicate adjective

This is the most natural way to say it in an ordinary statement.

A rough learner-friendly guide is:

ANN-mark-inn er AHL-var-leh-gur

A few helpful points:

• Stress usually falls on the first syllable in Icelandic words.
• annmarkinn is stressed at the start: ANN-
• The r is an Icelandic r, usually a tapped or rolled sound.
• The g in alvarlegur is not always a hard English g sound; it is softer in normal Icelandic pronunciation.

You do not need perfect pronunciation right away, but keeping the first-syllable stress is very important.

Annmarki is a real and useful word, but it can sound a bit more formal or written than some everyday alternatives.

It can mean things like:

• flaw
• defect
• drawback
• shortcoming

In more everyday speech, Icelanders might also use words like galli in some contexts for flaw or defect.

So annmarkinn er alvarlegur sounds perfectly correct, but somewhat formal depending on context.

Sometimes, depending on context, yes—but annmarki is not exactly the same as problem.

It usually points to:

• a specific flaw
• a defect
• a weakness
• a drawback

So it is closer to the flaw is serious or the defect is serious than to the problem is serious.

If you wanted a more general word like problem, Icelandic would often use vandamál instead.

The dictionary forms are:

• annmarki = flaw, defect, drawback
• alvarlegur = serious
• vera = to be

The sentence uses:

• annmarkinn = definite form of annmarki
• er = present tense of vera
• alvarlegur = the correct agreeing adjective form for this subject

So if you are learning vocabulary, those are the forms you would usually look up.
