אני לא רוצה לוותר על ההזדמנות הזאת, כי היא חשובה לי.

Not in writing. The spelling רוצה can be:

• masculine singular: rotze
• feminine singular: rotza

So this sentence could be said by either a male or a female speaker. You only hear the difference in pronunciation, not in the spelling.

In a simple sentence, לא usually comes before the verb or predicate it negates. So:

• אני רוצה = I want
• אני לא רוצה = I do not want

That is the normal Hebrew word order.

Because after a verb like רוצה (want), Hebrew normally uses an infinitive, just like English often uses to + verb.

• רוצה לוותר = want to give up

The ל- at the beginning of לוותר is part of the infinitive form and often corresponds to English to.

Because לוותר usually takes the preposition על when you say what is being given up.

• לוותר על משהו = to give up something / to forgo something

So לוותר על ההזדמנות הזאת means to give up this opportunity or to pass up this opportunity. It is best learned as a set expression: לוותר על.

Because ההזדמנות הזאת is not a direct object here. It comes after the preposition על.

Hebrew uses את only before a definite direct object with no preposition. Once you have a preposition like על, you do not use את.

So:

• אני רוצה את ההזדמנות הזאת = I want this opportunity
• אני רוצה לוותר על ההזדמנות הזאת = I want to give up this opportunity

Because the basic noun is הזדמנות, and Hebrew adds the definite article ה- to make it the opportunity.

So:

• הזדמנות = opportunity
• ההזדמנות = the opportunity

The spelling ends up with two ה letters because one belongs to the word itself and one is the definite article.

That is the normal Hebrew pattern with this/that after a definite noun.

• הספר הזה = this book
• האישה הזאת = this woman
• ההזדמנות הזאת = this opportunity

In Hebrew, both the noun and the demonstrative are marked as definite in this structure.

Because Hebrew demonstratives like this and that usually come after the noun:

• הספר הזה = this book
• ההזדמנות הזאת = this opportunity

This is different from English, where this comes before the noun.

Because הזדמנות is a feminine singular noun, and Hebrew pronouns must match the noun’s grammatical gender and number.

So when you refer back to הזדמנות, you use feminine singular היא.

In English, we would usually say it, but Hebrew still treats the noun as grammatically feminine.

Because adjectives in Hebrew agree with the noun they describe.

Since הזדמנות is feminine singular, the adjective must also be feminine singular:

• חשוב = important, masculine singular
• חשובה = important, feminine singular

So היא חשובה means it is important, referring to a feminine noun.

Hebrew usually leaves out the verb to be in the present tense.

So:

• היא חשובה לי literally looks like she/it important to me
• but it means it is important to me

This is completely normal in Hebrew.

לי literally means to me.

It is made from:

• ל- = to
• -י = me / my first-person singular suffix

So חשובה לי literally means important to me.

Sometimes yes, especially in casual speech or when the context is very clear. But כי היא חשובה לי is clearer and more complete.

Since Hebrew has no present-tense is here, the pronoun היא helps make the subject explicit.

You can also say ההזדמנות הזו. Both are correct.

• ההזדמנות הזאת
• ההזדמנות הזו

Both mean this opportunity. הזאת is extremely common in everyday Hebrew. הזו is also normal, and some speakers may feel it is slightly more formal or slightly more literary, depending on context.

This is the standard, neutral order:

אני לא רוצה לוותר על ההזדמנות הזאת, כי היא חשובה לי.

Hebrew does allow some flexibility for emphasis, but this version is the most natural one for a learner to use. If you change the order, it can sound more emphatic, more marked, or more literary.
