Maten är klar nu.

Because maten is the definite form of mat.

• mat = food
• maten = the food

In Swedish, definiteness is often shown by adding an ending to the noun instead of using a separate word like the in English.

So:

• mat = food
• maten = the food

In this sentence, Swedish is talking about a specific meal or food that both speaker and listener already know about, so maten is natural.

It can mean both, depending on context.

In everyday speech, maten är klar nu often means something like:

• the food is ready now
• dinner is ready now
• the meal is ready now

If someone calls people to the table, maten often refers to the meal being served, not just food in a general sense.

Here, klar means ready.

So maten är klar means the food is ready to be eaten or served.

But klar can also mean other things in other contexts, such as:

• finished
• done
• clear

For example:

• Jag är klar. = I’m done.
• Är du klar? = Are you ready? / Are you done?

So the exact English translation depends on the situation.

Because klar agrees with the noun maten, and maten is a common gender noun.

In Swedish, adjectives often change form depending on the noun.

• common gender singular: klar
• neuter singular: klart
• plural: klara

Since mat is a common gender noun, the definite singular maten takes klar:

• Maten är klar.

Compare:

• Huset är klart. = The house is ready / finished.
• Böckerna är klara. = The books are ready.

Because Swedish normally follows the V2 rule in main clauses: the finite verb comes in the second position.

In this sentence:

• Maten = first element
• är = second element
• klar nu = rest of the sentence

So Maten är klar nu follows normal Swedish word order.

This rule becomes especially noticeable when something other than the subject comes first. For example:

• Nu är maten klar.

Here nu comes first, so the verb är still has to stay in second position, before maten.

Yes, absolutely.

Both are natural:

• Maten är klar nu.
• Nu är maten klar.

The difference is mainly about emphasis:

• Maten är klar nu puts the topic first: the food, and then says it is ready now.
• Nu är maten klar emphasizes now more strongly, often with a sense like now it’s ready.

Both are very common.

Nu means now, and it adds a time sense.

Without it:

• Maten är klar. = The food is ready.

With it:

• Maten är klar nu. = The food is ready now.

This can suggest a contrast, for example:

• it wasn’t ready before
• you can come eat now
• the waiting is over

So nu often makes the sentence feel more immediate.

A few things may be useful:

• maten is roughly pronounced MAH-ten
• är has a vowel sound that does not exist exactly in English
• klar has a long a sound, somewhat like klaar
• nu sounds like nyy, with a Swedish u sound that is different from English oo

Also, in natural speech, är is often pronounced less strongly than learners expect.

A rough learner-friendly approximation might be:

• MAH-ten ehr klaar ny

But it is better to listen to native audio, especially for är and nu, because those vowel sounds are hard to guess from spelling.

Because Swedish usually puts the definite meaning on the noun itself with a suffix.

So instead of:

• the food

Swedish often says:

• maten

This is one of the most important differences between English and Swedish grammar.

A few examples:

• bok = book

• boken = the book

• hus = house
• huset = the house

So in maten är klar nu, the -en already means the.

You usually would not say that here.

For food, klar is the natural word.
Redo usually means ready in the sense of a person or something prepared for action.

Natural examples:

• Maten är klar. = The food is ready.
• Jag är redo. = I am ready.
• Är du redo? = Are you ready?

So for a meal being finished and ready to serve, klar is the normal choice.

Yes. It is completely natural and very common in everyday Swedish.

Someone might say it:

• while cooking
• when calling people to eat
• when announcing that dinner is ready
• when the meal has just been finished

It sounds like normal spoken Swedish and works perfectly as a standalone sentence.
