אני רוצה להתחיל לקרוא את הספר הזה.

This is normal in Hebrew, just like in English.

The structure is:

• רוצה = want
• להתחיל = to start
• לקרוא = to read

So Hebrew is building the same kind of chain as English:

I want to start to read...

Only the first verb is conjugated here; the next two are infinitives.

In the present tense, Hebrew usually does not mark person clearly the way English does.

The form רוצה can mean:

• I want (if the speaker is masculine singular)
• you want
• he wants

depending on context.

Because of that, Hebrew often includes the subject pronoun in the present tense:

• אני רוצה = I want
• אתה רוצה = you want
• הוא רוצה = he wants

So אני is there to make I explicit.

It can be either, because in normal unvocalized Hebrew writing the masculine and feminine singular forms look the same:

• masculine: רוֹצֶה = rotze
• feminine: רוֹצָה = rotza

Both are written רוצה without vowel marks.

So this sentence could be said by either a man or a woman; only the pronunciation changes.

The prefix ל־ often marks the infinitive, roughly like English to before a verb.

So:

• להתחיל = to start
• לקרוא = to read

This is one of the first useful patterns to learn in Hebrew:
ל־ + verb form = to do something

Because להתחיל is the infinitive (to start), while מתחיל is a present-tense form (starting / starts / am starting, depending on context).

Compare:

• אני רוצה להתחיל = I want to start
• אני מתחיל = I am starting

After רוצה, Hebrew normally uses an infinitive, just like English uses to start after want.

את is the direct object marker. It comes before a definite direct object.

Here, the object is הספר הזה = this book, which is definite, so Hebrew uses את:

• אני קורא ספר = I am reading a book
  
  • no את, because book is indefinite
• אני קורא את הספר = I am reading the book
  
  • את is required

So in your sentence:

• לקרוא את הספר הזה = to read this book

English has no separate word for this, so learners often find את strange at first.

Because when Hebrew says this/that + noun in this pattern, the noun is normally definite, so it takes ה־.

So:

• הספר הזה = this book
• הילד הזה = this boy
• המכונית הזאת = this car

A literal word-for-word gloss is often:

• הספר הזה = the book this

That sounds odd in English, but it is standard Hebrew structure.

That is the normal Hebrew order when this/that directly modifies a noun:

• הספר הזה = this book
• הבית הזה = this house

So Hebrew usually says:

the noun + this/that

There is also another pattern:

• זה הספר = this is the book

So:

• הספר הזה = this book
• זה הספר = this is the book

Those are different structures.

Because זה has to agree with the noun in gender and number.

ספר is masculine singular, so the correct form is:

• הספר הזה

If the noun were feminine singular, you would normally use:

• המחברת הזאת = this notebook

So in your sentence, הזה matches ספר.

No. לקרוא can also mean to call.

For example:

• לקרוא ספר = to read a book
• לקרוא לחבר = to call a friend
• לקרוא בשם = to call by a name

The context tells you which meaning is intended. Since the object here is ספר, the meaning is clearly to read.

Because את הספר הזה is the object of לקרוא.

The sentence is built like this:

• אני רוצה = I want
• להתחיל = to start
• לקרוא את הספר הזה = to read this book

So the object stays next to the verb it belongs to, which is לקרוא.

This is the most natural default order.

A common pronunciation is:

ani rotze lehatchil likro et hasefer haze

If the speaker is female:

ani rotza lehatchil likro et hasefer haze

A rough stress guide:

• a-NI
• rot-ZE / rot-ZA
• le-hat-CHIL
• li-KRO
• et
• ha-SE-fer
• ha-ZE

The ch in lehatchil is like the sound in Scottish loch or German Bach, not like English ch in chair.

Sometimes, but usually it is better to keep it.

Because present-tense forms like רוצה do not clearly show person, אני רוצה is the normal, clear way to say I want.

In conversation, if the context is very obvious, a speaker might drop אני, but for learners the safest and most natural choice is:

אני רוצה להתחיל לקרוא את הספר הזה
