Questions & Answers about Hjálmurinn er öruggur.

What does the ending -inn on Hjálmurinn mean?

The ending -inn is the definite article in Icelandic, meaning “the”.

• Hjálmur = helmet
• Hjálmurinn = the helmet

Instead of putting a separate word in front of the noun (like the in English), Icelandic usually attaches the definite article to the end of the noun as a suffix.

What is the basic dictionary form of Hjálmurinn?

The dictionary form is hjálmur.

When you look up nouns in an Icelandic dictionary, you look for:

• Nominative singular, indefinite (without the article)

So:

• hjálmur → dictionary form
• hjálmurinn → “the helmet” (nominative singular, definite)

What gender is hjálmur, and how do I know?

Hjálmur is masculine.

Clues:

• Many nouns ending in -ur in the nominative singular are masculine (e.g. stóll, bíll, hjálmur).
• The adjective öruggur and the article -inn both use masculine forms, which confirms the gender:
  
  • masculine noun: hjálmurinn
  • masculine adjective: öruggur

Why is it öruggur, not something like öruggt or örugg?

Icelandic adjectives must agree with the noun in:

• Gender
• Number
• Case

Here:

• hjálmurinn is masculine, singular, nominative.
• So the adjective also has to be masculine, singular, nominative → öruggur.

Other main forms of this adjective (strong declension) are:

• Masculine: öruggur
• Feminine: örugg
• Neuter: öruggt

So, for example:

• Hjálmurinn er öruggur. – The helmet is safe.
• Töskan er örugg. – The bag is safe. (feminine)
• Kerfið er öruggt. – The system is safe. (neuter)

What case are Hjálmurinn and öruggur in?

Both are in the nominative singular.

• Hjálmurinn is the subject, so it’s nominative.
• With the verb er (from að vera – “to be”), a describing adjective normally also appears in the nominative. This is called a predicate adjective.

So:
Hjálmurinn (nom.) er öruggur (nom.).

What exactly does er mean, and why isn’t it something like ert or eru?

Er is a form of the verb að vera (to be). It can mean am / is / are, depending on the subject.

Present tense forms are:

• ég er – I am
• þú ert – you are (singular)
• hann / hún / það er – he / she / it is
• við erum – we are
• þið eruð – you are (plural)
• þeir / þær / þau eru – they are

In Hjálmurinn er öruggur, the subject is third‑person singular (hjálmurinn = it/he), so we use er.

How do I pronounce Hjálmurinn and öruggur?

Approximate guidance (not strict IPA):

Hjálmurinn

• hj – a breathy “hy” sound (like saying h
  • y together), somewhat like the “h” in huge, but further forward.
• á – like ow in cow.
• lm – pronounced clearly l then m.
• Final -urinn – -u-rin with a light n; the last n is often not strongly separated in fast speech.

Very roughly: HYOWL-mu-rin.

öruggur

• ö – a rounded vowel; somewhat like the vowel in British bird, but with rounded lips.
• ru – like ru in rude but shorter.
• gg – a hard g sound, often a bit doubled in length.
• Final -ur – very short, almost like -r with a tiny vowel.

Very roughly: UR-ug-gur (with u like in burn, but rounded).

Can I say Hjálmur er öruggur without -inn? Does that change the meaning?

Yes, you can, and it does change the meaning slightly.

• Hjálmur er öruggur.

  • Means “A helmet is safe” or “Helmets (in general) are safe” – a more general statement.

• Hjálmurinn er öruggur.

  • Means “The helmet is safe” – you’re talking about a specific helmet that both speaker and listener know about.

So the difference is just like a helmet vs the helmet in English, but expressed with or without the article suffix -inn.

How would I say “The helmet is not safe” in Icelandic?

You add the negation ekki (not) after the verb er:

• Hjálmurinn er ekki öruggur. – The helmet is not safe.

Word order pattern:

• Subject + er
  • ekki
    • adjective
      
      • Hjálmurinn
        • er
          • ekki
            • öruggur

How do I turn this into a yes–no question: “Is the helmet safe?”

In Icelandic yes–no questions with er, you usually put the verb first:

• Er hjálmurinn öruggur? – Is the helmet safe?

So the order changes from:

• Hjálmurinn er öruggur. → statement
  to
• Er hjálmurinn öruggur? → question

How would this sentence look in the plural: “The helmets are safe”?

You need to put both the noun and the adjective in the plural nominative:

• Hjálmarnir eru öruggir. – The helmets are safe.

Changes:

• hjálmurinn → hjálmarnir (masculine nominative plural definite)
• er → eru (3rd person plural of að vera)
• öruggur → öruggir (masculine nominative plural adjective)

What’s the difference between öruggur and örugglega / öruggt?

They are related but used differently:

• öruggur – adjective, meaning safe / secure / sure

  • Hjálmurinn er öruggur. – The helmet is safe.

• öruggt (neuter singular of the adjective, often used adverbially)

  • Can mean for sure / definitely in some expressions:
  • Það er öruggt. – That is certain / That’s for sure.

• örugglega – adverb, roughly surely / probably / definitely

  • Hann kemur örugglega. – He will surely/probably come.

So öruggur describes a thing or person, while örugglega / öruggt often describe how sure you are about something.

Can I move the adjective in front, like in English, and say something like “the safe helmet”?

Yes, but you then get an attributive adjective instead of a sentence:

• öruggur hjálmur – a safe helmet (indefinite)
• öruggi hjálmurinn – the safe helmet (definite, standard pattern without hinn)

Compare:

• Hjálmurinn er öruggur. – The helmet is safe. (full sentence, with er)
• öruggi hjálmurinn – the safe helmet (just a noun phrase, no verb)

Note two things:

1. When the adjective comes before a definite noun, it usually takes a different (weak) ending → öruggi hjálmurinn.
2. In your original sentence the adjective is after the verb er, so it uses the strong form: öruggur.

Can öruggur also mean “sure” as in “I am sure”?

Yes. Öruggur can mean both “safe / secure” and “sure / certain”, depending on context.

For example:

• Ég er öruggur. – I am sure / I am confident (said by a man).
• Ég er örugg. – same meaning, said by a woman (feminine form of the adjective).

So the word is flexible: it can describe physical safety (a helmet, a system) or emotional/mental certainty or confidence (a person).
