Stjórnandinn rekur fyrirtækið.

They are the definite article in Icelandic, attached to the noun itself.

So:

• stjórnandi = manager
• stjórnandinn = the manager
• fyrirtæki = company
• fyrirtækið = the company

Unlike English, Icelandic usually does not use a separate word like the before the noun. Instead, it adds the article as an ending.

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

So English:

• the manager
• the company

becomes Icelandic:

• stjórnandinn
• fyrirtækið

There is a separate demonstrative-type word that can sometimes function like that/the, but in ordinary sentences like this, the suffix is the normal choice.

Rekur is the 3rd person singular present tense of the verb reka.

That means it is the form used with:

• he
• she
• it
• singular nouns like the manager

So:

• ég rek = I run / operate
• þú rekur = you run / operate
• hann/hún/það rekur = he/she/it runs / operates

In this sentence, stjórnandinn is singular, so rekur is the correct form.

Here reka means to run, to operate, or to manage a business.

So Stjórnandinn rekur fyrirtækið means that the manager is in charge of operating the company.

Be careful, though: reka is a very common Icelandic verb with several meanings depending on context, including ideas like:

• run / operate
• drive
• carry on
• sometimes even expel or chase away

In this sentence, the business meaning is the natural one.

In this sentence, the normal interpretation is:

• stjórnandinn = subject = the one doing the action
• fyrirtækið = object = the thing being run

There are two big clues:

1. Word order
   The basic order here is subject + verb + object, just like in English.

2. Case
   The verb reka takes an accusative object, so fyrirtækið is the object.

One small complication: for many neuter nouns in Icelandic, the nominative and accusative forms are identical. So fyrirtækið looks the same whether it is subject or object. In this sentence, word order helps you understand it.

Because fyrirtæki is a neuter noun, and for neuter nouns, the nominative and accusative are often the same.

So:

• fyrirtækið can be nominative singular definite
• fyrirtækið can also be accusative singular definite

That is very normal in Icelandic. You often figure out the role from:

• the verb
• word order
• context

Because the definite ending is being added to a noun that already ends in -i.

Very roughly:

• stjórnandi
  • definite article
• becomes stjórnandinn

That double n is a normal result of how the definite article attaches in Icelandic. You do not need to think of it as two separate pieces in everyday use; just learn stjórnandinn as the correct definite form.

Yes. Depending on context, stjórnandi can mean things like:

• manager
• director
• administrator
• leader
• even host/presenter in some contexts, especially media

So the exact English translation depends on the situation. In a business sentence with fyrirtækið, manager is a very natural translation.

You would usually remove the definite endings:

• Stjórnandi rekur fyrirtæki.

That gives the basic indefinite sense:

• a manager runs a company
• or sometimes a more general statement like managers run companies

As often in Icelandic, bare nouns without the article can be a bit flexible depending on context.

The sentence uses the most straightforward word order:

• Stjórnandinn = subject
• rekur = verb
• fyrirtækið = object

So it is a standard SVO pattern.

However, Icelandic word order is more flexible than English word order because Icelandic has case and also follows verb-second rules in main clauses. That means other orders are possible for emphasis or style, but this sentence is the neutral, beginner-friendly order.

A rough English-friendly guide would be something like:

• Stjórnandinn ≈ STYOR-nahn-din
• rekur ≈ REH-kur
• fyrirtækið ≈ FI-ri-tye-kith

A few important notes:

• j + ó in stjór- gives a sound somewhat like styor
• æ is not like English a; it is closer to a sound like eye or yeh, depending on the environment and accent
• ð is like the th in this, but at the end of a word it can be weaker
• y in Icelandic is pronounced like i, not like English y

If you want to sound natural, it is best to listen to native audio, because Icelandic pronunciation is hard to guess from English spelling habits.

Here stjórnandinn is in the nominative singular definite.

That is because it is the subject of the sentence.

So the structure is:

• stjórnandinn = nominative singular definite
• rekur = 3rd person singular present
• fyrirtækið = accusative singular definite

This is a very common basic sentence pattern in Icelandic.

Not necessarily. The Icelandic present tense, like the English present tense, can express different kinds of present meaning.

So Stjórnandinn rekur fyrirtækið can mean:

• The manager runs the company
• The manager is in charge of the company
• The manager operates the company

It often describes a general fact or ongoing situation, not just an action happening at this exact moment.
