Världen är stor.

In Swedish, the definite article is usually added to the end of the noun instead of being a separate word in front.

• värld = world
• världen = the world

The ending -en is the definite ending for many en-words in Swedish.

So unlike English:

• the world

Swedish often says it as one word:

• världen

Är is the present tense of the Swedish verb vara, which means to be.

A useful thing for English speakers is that Swedish does not change this verb in the present tense depending on the subject:

• jag är = I am
• du är = you are
• han är = he is
• världen är = the world is

So är works for all persons in the present tense.

This is about adjective agreement.

The adjective stor changes form depending on the noun it describes.

Here are the basic forms:

• stor = used with a singular en-word
• stort = used with a singular ett-word
• stora = used with plural nouns, and also often with definite nouns when the adjective comes before the noun

In Världen är stor, the noun världen is singular and is an en-word, so the adjective form is stor.

Compare:

• en stor värld = a big world
• världen är stor = the world is big
• ett stort hus = a big house
• huset är stort = the house is big

Good question. This is because the adjective is in a predicative position, not directly before the noun.

Compare these two patterns:

1. Before the noun

   • den stora världen = the big world

2. After a verb like är

   • världen är stor = the world is big

When the adjective comes after är, it usually agrees mainly with gender and number, not with definiteness in the same way. So:

• världen är stor
• not världen är stora

The word order is:

• Världen = subject
• är = verb
• stor = adjective / subject complement

So the pattern is:

• Subject + verb + adjective

This is very similar to English:

• The world is big

That makes this sentence quite straightforward for English speakers.

A simple learner-friendly approximation is:

• VAIRL-den

A few pronunciation notes:

• ä sounds somewhat like the vowel in air for many learners, though it is not exactly the same.
• The rld cluster in värld can be tricky.
• The stress is on the first syllable: VÄRLD-en

If you say something close to VAIRL-den, Swedish speakers will usually understand you.

A rough English approximation is:

• air

But again, the Swedish ä is not exactly the same as English air.

It is a very common word, so it is worth practicing early. You will hear är constantly in Swedish.

It is an en-word:

• en värld = a world
• världen = the world

This matters because it affects adjective forms and some other grammar patterns.

For example:

• en stor värld = a big world
• världen är stor = the world is big

If it were an ett-word, the adjective would normally be stort instead.

Grammatically, you can form that sentence, but it usually does not mean the same thing in a natural way.

• Världen är stor = The world is big
• En värld är stor = A world is big

The second sentence sounds odd in most situations, because a world is not usually what you want to talk about. In Swedish, just as in English, the definite form is the natural choice here.

Because Swedish often marks definiteness with a suffix attached to the noun.

So instead of:

• the + world

you get:

• värld + en → världen

This is one of the biggest differences from English noun structure.

However, Swedish can also use a separate definite word in some cases, especially when there is an adjective before the noun:

• den stora världen = the big world

So Swedish sometimes uses both:

• a separate definite word (den)
• and the definite noun ending (-en)

But in Världen är stor, only the noun needs the definite ending.

Stor most often means big or large.

Depending on context, it can sometimes correspond to English words like great, but in a sentence like Världen är stor, the natural meaning is simply big/large.

So for a learner, the safest understanding here is:

• stor = big

Yes. Världen är stor is a completely natural and correct Swedish sentence.

It is short, simple, and idiomatic. It works well as an early example because it shows:

• a definite noun: världen
• the common verb är
• adjective agreement: stor

So it is a very useful beginner sentence.
