אני לא זורק את הקבלה, כי אולי נרצה להחליף את החולצה מחר.

את is the Hebrew direct object marker. It does not have a separate meaning in English, so it usually is not translated.

You use את before a definite direct object, such as:

• a noun with ה־ (the)
• a proper name
• a pronoun

So:

• את הקבלה = the receipt as the object of זורק
• את החולצה = the shirt as the object of להחליף

A useful contrast:

• אני זורק קבלה = I throw away a receipt / receipt
• אני זורק את הקבלה = I throw away the receipt

זורק is the masculine singular present form.

In Hebrew, present-tense forms agree with the speaker's gender and number:

• זורק = masculine singular
• זורקת = feminine singular
• זורקים = masculine plural / mixed plural
• זורקות = feminine plural

So this sentence assumes the speaker is male.
If a woman were saying it, it would be:

אני לא זורקת את הקבלה...

Hebrew often uses the present tense for something happening right now or for a current decision:

• אני לא זורק את הקבלה = I’m not throwing away the receipt

That sounds natural when the speaker is talking about what they are doing at the moment.

If you used אזרוק, the meaning would shift more toward:

• I will not throw away the receipt
• I won’t throw away the receipt

So the present tense here fits the idea of a present action or immediate choice.

Also, Hebrew present tense can cover both:

• I throw
• I am throwing

Context tells you which one is meant.

In Hebrew, subject pronouns are often optional because the verb already shows who the subject is.

But there is an important difference here:

In the present tense

זורק does not tell you the person clearly by itself. It can mean, depending on context:

• I throw / am throwing
• you throw / are throwing (masculine singular)
• he throws / is throwing

So אני helps make the subject clear.

In the future tense

נרצה already clearly means we will want, so אנחנו is not necessary.

You could say:

• כי אולי אנחנו נרצה להחליף את החולצה מחר

But it is usually more natural to leave אנחנו out unless you want emphasis.

נרצה is the first person plural future form of לרצות (to want).

So by itself:

• נרצה = we will want

When you add אולי (maybe / perhaps), Hebrew often expresses possibility this way:

• אולי נרצה = maybe we’ll want
• very naturally in English: we might want

Hebrew does not need a separate verb exactly like English might here.
Instead, אולי + future tense often carries that meaning.

After verbs like want, Hebrew usually uses an infinitive to say what someone wants to do.

So:

• נרצה = we will want
• להחליף = to exchange / to replace

Together:

• נרצה להחליף = we will want to exchange

This is very similar to English:

• want to exchange

The ל־ at the start of להחליף is the normal marker of the infinitive, like to in English.

It can mean all of those, depending on context.

Common meanings of להחליף include:

• to exchange
• to replace
• to switch

In this sentence, because we have:

• receipt
• shirt
• tomorrow

the natural meaning is exchange the shirt, for example for another size or color.

So here להחליף את החולצה most naturally means:

• to exchange the shirt

לא is the normal way to negate verbs in Hebrew in the:

• present
• past
• future

So:

• אני לא זורק = I am not throwing
• לא רציתי = I didn’t want
• לא נרצה = we won’t want

English speakers sometimes confuse this with אין, but אין is used for:

• non-existence
• absence
• possession

For example:

• אין קבלה = there is no receipt
• אין לי קבלה = I don’t have a receipt

But with a normal verb like זורק, you use לא.

The prefix ה־ is the Hebrew definite article, meaning the.

So:

• קבלה = receipt
• הקבלה = the receipt

and:

• חולצה = shirt
• החולצה = the shirt

Unlike English, Hebrew attaches the directly to the noun as a prefix.

Because both nouns are definite, they also take את as direct objects:

• את הקבלה
• את החולצה

Yes. Hebrew word order is fairly flexible, especially with words like אולי and מחר.

The given sentence is very natural:

• כי אולי נרצה להחליף את החולצה מחר

But other orders are also possible, for example:

• כי מחר אולי נרצה להחליף את החולצה
• כי אולי מחר נרצה להחליף את החולצה

These all mean roughly the same thing, but the emphasis can shift slightly:

• אולי early in the clause sounds very natural
• מחר at the end is also very natural and common

So the original order is not the only possible one, just a normal everyday choice.

Literally, לזרוק means to throw.

But in everyday Hebrew, it very often also means:

• throw away
• throw out
• discard

when the context makes that clear.

Since the object here is the receipt, the natural meaning is:

• I’m not throwing away the receipt

If someone wanted to be extra explicit, they might say something like:

• לזרוק לפח = throw in the trash

But in this sentence, just זורק is enough.

כי is the normal everyday word for because.

So:

• כי אולי נרצה להחליף את החולצה מחר = because maybe we’ll want to exchange the shirt tomorrow

It is the most common and straightforward choice in ordinary speech.

Hebrew does have other ways to express because, but כי is the simple, neutral one that learners should know well first.
