I år vill jag läsa fler böcker på svenska.

This is because Swedish is a V2 language in main clauses. V2 means the finite verb must come in the second position.

So in:

I år vill jag läsa fler böcker på svenska.

• I år = first position
• vill = second position
• jag = comes after the verb

If you start with the subject instead, you get:

Jag vill läsa fler böcker på svenska i år.

That is also correct. The difference is mainly emphasis:

• I år ... puts focus on this year
• Jag ... starts more neutrally with I

I år means this year.

It is a fixed expression:

• i dag = today
• i morgon = tomorrow
• i veckan = this week
• i år = this year

Even though i often means in, you should learn i år as the normal Swedish way to say this year.

After the modal verb vill (want to), Swedish normally uses the bare infinitive, without att.

So:

• jag vill läsa = I want to read
• jag kan läsa = I can read
• jag ska läsa = I will/am going to read

Not:

• jag vill att läsa ❌

This is similar to English, where we say I can read, not I can to read.
But unlike English want to read, Swedish uses vill läsa, without a word corresponding to to here.

Läsa is the infinitive form of the verb, meaning to read.

It is used here because it follows the modal verb vill. In Swedish, modal verbs are followed by the infinitive:

• vill läsa = want to read
• kan läsa = can read
• måste läsa = must read

So vill is the conjugated verb, and läsa stays in the infinitive.

Use fler with countable nouns and mer with uncountable nouns.

• fler böcker = more books
• fler människor = more people

But:

• mer vatten = more water
• mer tid = more time

Since books can be counted, Swedish uses fler.

Also, fler is the comparative form connected to många (many), while mer is connected to mycket (much).

This is a very common question.

• fler = more
• flera = several

So:

• Jag vill läsa fler böcker = I want to read more books
• Jag vill läsa flera böcker = I want to read several books

Fler implies comparison: more than before, more than now, more than some other amount.
Flera just means a number greater than a few, without directly comparing.

Because Swedish, like English, often uses a bare plural for things in general.

So:

• läsa böcker = read books
• köpa äpplen = buy apples

In this sentence, fler böcker means more books in a general sense, not the books or some specific books.

Compare:

• fler böcker = more books
• de fler böckerna = the additional books / the more books (specific)
• några fler böcker = some more books

Because Swedish plural formation is different from English. You do not usually add a simple -s.

The word is:

• en bok = a book
• böcker = books

This is an irregular-looking plural from an English perspective, but it is a normal Swedish pattern. Many common Swedish nouns change their vowel in the plural:

• en bok → böcker
• en hand → händer
• en stad → städer

So böcker is just the correct plural form you need to learn with the noun.

When Swedish talks about the language something is spoken, written, or read in, it very often uses på:

• tala på svenska = speak in Swedish
• skriva på engelska = write in English
• läsa på svenska = read in Swedish

So böcker på svenska means books in the Swedish language.

This is one of those patterns that is best learned as a set phrase.

Yes, but the meaning can shift.

• böcker på svenska = books written in Swedish / books in the Swedish language
• svenska böcker = Swedish books

Svenska böcker can sometimes mean books from Sweden or books that are Swedish in character, not just books in the Swedish language. So if you specifically want to talk about the language, böcker på svenska is clearer.

Because in Swedish, names of languages are usually not capitalized unless they begin the sentence.

So:

• svenska = Swedish
• engelska = English
• tyska = German

This is different from English, where language names are capitalized.

So:

• på svenska ✅
• på Svenska ❌

Yes, absolutely. That is also correct.

Compare:

• I år vill jag läsa fler böcker på svenska.
• Jag vill läsa fler böcker på svenska i år.

Both mean the same thing, but the first version emphasizes this year more strongly because it comes first.

This kind of movement is very common in Swedish, but remember: in a main clause, the finite verb still has to stay in second position.
