Grunnspillet er klart.

Norwegian often makes compound nouns where English would use two words.

• grunn = base, foundation
• spill = game

So grunnspill means base game.
Then -et is added to make it definite, giving grunnspillet = the base game.

This kind of compounding is very common in Norwegian.

Because Norwegian usually adds the definite article to the end of the noun instead of putting a separate word like the in front.

• et grunnspill = a base game
• grunnspillet = the base game

The ending -et shows that the noun is:

• singular
• definite
• neuter

In this sentence, the is built into the noun itself.

English uses a separate article:

• the base game

Norwegian often uses a suffix:

• grunnspillet

So grunnspillet already includes the idea of the.

The sentence gives you two clues:

1. The indefinite form is et grunnspill
   The article et marks a neuter noun.

2. The definite form is grunnspillet
   The ending -et is the usual definite singular ending for many neuter nouns.

Because grunnspill is neuter, other words in the sentence must match it.

Because klart is the neuter singular form of the adjective klar.

When an adjective comes after er and describes the subject, it usually agrees with the subject in gender and number.

Here the subject is grunnspillet, which is neuter singular, so we use:

• klar for common gender singular
• klart for neuter singular
• klare for plural

So:

• Boken er klar = The book is ready
• Spillet er klart = The game is ready
• Bøkene/spillene er klare = The books/games are ready

Er is the present tense of å være, which means to be.

So:

• jeg er = I am
• du er = you are
• han/hun/det er = he/she/it is

In this sentence, er simply means is.

Klart can mean several things depending on context, such as:

• ready
• finished
• done
• sometimes clear

With Grunnspillet er klart, the most natural meaning is often something like:

• The base game is ready
• The base game is finished

If this is about video games, it could mean the main game is complete or available, especially in contrast to expansions or extra content.

This is the normal Norwegian sentence pattern:

• Grunnspillet = subject
• er = verb
• klart = predicative adjective

So it follows the basic order:

subject + verb + complement

Very straightforward:

• Grunnspillet er klart.

If something else came first, Norwegian would still keep the verb in second position:

• Nå er grunnspillet klart. = Now the base game is ready.

Usually not if you simply mean the base game in general.

• grunnspillet already means the base game

Adding det would normally change the meaning to something more like:

• that base game

So:

• Grunnspillet er klart = The base game is ready
• Det grunnspillet er klart = That base game is ready

The second one is more specific and contrastive.

Plural would be:

• grunnspill = base games
• grunnspillene = the base games

And the adjective changes too:

• Grunnspillene er klare. = The base games are ready.

Notice the pattern:

• singular neuter: klart
• plural: klare
