אני לא רוצה לטעות בתרגיל הזה.

אני means I. In Hebrew, subject pronouns are often dropped in the past and future because the verb itself usually shows the person clearly. But in the present tense, forms like רוצה do not show person, only gender and number.

So רוצה could mean:

• I want if the speaker is masculine
• you want for a masculine singular you
• he wants

Because of that, אני is often included to make the subject clear. You can omit it if the context already makes it obvious, but אני לא רוצה... is the clearest and most natural version.

רוצה is the present-tense form of לרצות, meaning to want.

In this sentence, it is the masculine singular form, pronounced rotzeh. That means the speaker is grammatically masculine.

A few useful comparisons:

• אני רוצה = I want if the speaker is male
• אני רוצה = I want if the speaker is female too, but then it is pronounced rotzah
• אנחנו רוצים = we want for a masculine or mixed group
• אנחנו רוצות = we want for an all-female group

So in normal unpointed writing, masculine singular and feminine singular look the same here, but the pronunciation is different.

In normal Hebrew, לא usually goes before the main verb being negated. So:

אני לא רוצה לטעות
means I do not want to make a mistake

This is the standard everyday way to say it.

You can say אני רוצה לא לטעות, but that sounds more marked or more deliberate, almost like I want specifically not to make a mistake. The sentence you were given is the most natural way to express the idea.

The ל here marks the infinitive, like English to in to go, to write, or to make a mistake.

So:

• לטעות = to make a mistake / to be mistaken

After a verb like רוצה, Hebrew normally uses an infinitive:

• רוצה לטעות = wants to make a mistake
• לא רוצה לטעות = does not want to make a mistake

So the ל is not a separate word here; it is attached directly to the infinitive.

Not exactly. לטעות more literally means to err or to be mistaken. But in natural English, the best translation is often to make a mistake.

That is a very common difference between Hebrew and English:

• English often uses make + noun: make a mistake
• Hebrew often uses a single verb: לטעות

A related noun is:

• טעות = mistake

So:

• עשיתי טעות = I made a mistake
• טעיתי = I was mistaken / I made a mistake

Both are possible in Hebrew, but לטעות is very natural here.

Hebrew prepositions like ב, ל, and כ are usually attached directly to the following word.

So:

• ב + תרגיל = בתרגיל

But here the phrase is definite because of הזה, so underneath it is really like:

ב + התרגיל הזה

When ב combines with the definite article ה, they contract. So you do not write a separate ה before תרגיל here. In pronunciation, it comes out like ba-targil, not be-targil.

So בתרגיל הזה means in this exercise, and the definiteness is still there even though the ה is not written separately.

Because Hebrew demonstratives like this and that normally come after the noun, not before it.

So:

• התרגיל הזה = this exercise
• הספר ההוא = that book

This is different from English word order. English says this exercise, but Hebrew says the equivalent of the exercise this.

That is completely normal in Hebrew.

Because תרגיל is a masculine singular noun, and the demonstrative has to agree with it.

So:

• masculine singular: הזה
• feminine singular: הזאת

That gives:

• התרגיל הזה = this exercise because תרגיל is masculine
• השאלה הזאת = this question because שאלה is feminine

So הזה tells you that תרגיל is masculine singular.

Because את is used only for a definite direct object.

Here, בתרגיל הזה is not a direct object. It is a prepositional phrase introduced by ב, meaning something like in this exercise.

Compare:

• אני רואה את התרגיל הזה = I see this exercise
  Here את is needed because התרגיל הזה is the direct object.

• אני טועה בתרגיל הזה = I make a mistake in this exercise
  Here בתרגיל הזה is attached to the preposition ב, so there is no את.

A common pronunciation is:

Ani lo rotzeh lit'ot ba-targil ha-zeh.

If the speaker is female, then רוצה is pronounced differently:

Ani lo rotzah lit'ot ba-targil ha-zeh.

A few pronunciation notes:

• אני = ani
• לא = lo
• רוצה = rotzeh or rotzah
• לטעות = lit'ot
• בתרגיל = ba-targil
• הזה = ha-zeh

In lit'ot, the ' shows the place of ע, which may sound like a slight break in pronunciation.
