מחר נפרוק את הארגזים האחרונים לפני שנצא לעבודה.

Hebrew often puts a time word like מחר at the start to set the scene: Tomorrow, ...

That is very natural word order. It highlights when the action will happen. Hebrew is fairly flexible, so you could also hear other orders, but starting with a time expression is extremely common.

Because Hebrew verbs usually already include the subject.

נפרוק means we will unload.
The prefix נ- here marks first person plural: we.

So Hebrew does not need אנחנו in this sentence. You could add אנחנו for emphasis, but normally it is unnecessary.

נפרוק is a future tense verb meaning we will unload.

It comes from the verb לפרוק = to unload.

So:

• לפרוק = to unload
• נפרוק = we will unload

This is one of the most useful things to notice in Hebrew: once you know the infinitive, the conjugated form often becomes easier to recognize.

את marks a definite direct object.

In this sentence, הארגזים האחרונים means the last boxes, which is definite. Because it is the direct object of נפרוק, Hebrew uses את before it.

Important:

• את does not mean with here.
• It usually does not get translated into English.
• Its job is grammatical: it tells you that the following noun phrase is the direct object.

So:

• נפרוק את הארגזים האחרונים = we will unload the last boxes

Because in Hebrew, when a noun is definite, its adjective is usually definite too.

Here:

• הארגזים = the boxes
• האחרונים = the last ones / last

Together:

• הארגזים האחרונים = the last boxes

This is a very important Hebrew pattern:

• noun + adjective
• and if the noun is definite, the adjective also gets ה־

Compare:

• ארגזים אחרונים = last boxes
• הארגזים האחרונים = the last boxes

Because Hebrew adjectives normally come after the noun they describe.

So Hebrew says:

• הארגזים האחרונים

Literally, that is closer to:

• the boxes the-last

But in natural English, of course, we say:

• the last boxes

This noun-then-adjective order is one of the basic word-order differences between Hebrew and English.

Because the adjective must agree with the noun in gender, number, and definiteness.

The noun ארגזים is:

• masculine
• plural
• definite

So the adjective must also be:

• masculine
• plural
• definite

That gives:

• האחרונים

If the noun were singular masculine, you would get:

• הארגז האחרון = the last box

If it were plural feminine, the adjective form would be different.

This means before we leave / before we go out.

It has two parts:

• לפני = before
• שנצא = that we will leave / that we go out

In smoother English, the whole phrase is simply:

• before we leave
• before we go out

In Hebrew, לפני ש־ is a very common way to say before followed by a full clause.

So:

• לפני שנצא לעבודה = before we leave for work

The ש־ is a conjunction meaning something like that, but in combinations like לפני ש־, it helps introduce a clause.

So:

• לפני = before
• שנצא = that we leave / that we go out

Together:

• לפני שנצא = before we leave

Also notice that ש־ is written attached to the next word in Hebrew, not as a separate word.

נצא is the future, first person plural form of לצאת = to go out / to leave.

So:

• לצאת = to leave
• נצא = we will leave

It looks a little irregular because לצאת is not a perfectly regular verb. The root is connected with יצא, and some forms change in ways that learners have to get used to.

For practical purposes, it is best to learn:

• אני אצא = I will leave
• אנחנו נצא = we will leave
• הוא יצא = he will leave

לעבודה literally means to work or for work, and it is the normal idiomatic choice here.

It is made of:

• ל־ = to
• עבודה = work

So:

• לצאת לעבודה = to leave for work / to go to work

Using אל העבודה would sound more like motion toward a specific workplace in a more literal or marked way. In everyday Hebrew, לעבודה is the natural expression.

Usually, with a full subject implied by the verb, לפני ש־ is the more natural pattern here.

So:

• לפני שנצא לעבודה = before we leave for work

Hebrew can sometimes use לפני + infinitive in other structures, but in this sentence, the finite clause with שנצא is the standard, natural choice.

For an English speaker, a good rule is:

• if Hebrew says before we leave, it will often use לפני ש־
  • a conjugated verb.

Yes, Hebrew has some flexibility.

For example, the sentence could be rearranged, but the original order is very natural:

• מחר נפרוק את הארגזים האחרונים לפני שנצא לעבודה.

This order sounds smooth because it goes:

1. time: מחר
2. main action: נפרוק
3. object: את הארגזים האחרונים
4. time relationship/subordinate clause: לפני שנצא לעבודה

So even though Hebrew allows variation, this sentence is a very standard and useful model.
