אנחנו עורמים ארגזי קרטון ליד עגלת המשא.

Yes. Hebrew present tense often covers both:

• simple present: we stack
• present progressive: we are stacking

So אנחנו עורמים can mean either one, depending on context. In this sentence, the natural English translation is usually we are stacking.

Because Hebrew present-tense verbs agree with the subject in number and gender.

• עורמים = masculine plural
• עורמות = feminine plural

The pronoun אנחנו can mean we for any group, but the verb shows whether the group is:

• all female → אנחנו עורמות
• male or mixed group → אנחנו עורמים

So this sentence suggests a male group or a mixed group.

Often, yes. Hebrew frequently drops subject pronouns when the subject is clear.

So you could say:

עורמים ארגזי קרטון ליד עגלת המשא

However, there is an important detail: in the present tense, the verb does not clearly show person the way English does. עורמים tells you plural masculine/mixed, but not specifically we rather than they. So אנחנו is helpful when you want to make the subject explicit.

Because את marks a definite direct object in Hebrew.

Here, ארגזי קרטון means cardboard boxes in an indefinite sense, not the cardboard boxes. Since the object is indefinite, Hebrew does not use את.

Compare:

• אנחנו עורמים ארגזי קרטון = We are stacking cardboard boxes
• אנחנו עורמים את ארגזי הקרטון = We are stacking the cardboard boxes

Because this is a construct chain in Hebrew.

The base noun is:

• ארגזים = boxes

But when it is followed by another noun to mean boxes of cardboard or cardboard boxes, it changes to the construct form:

• ארגזי קרטון

So:

• ארגזים = boxes
• ארגזי קרטון = cardboard boxes / boxes of cardboard

This is a very common Hebrew pattern.

Because קרטון here names the material, not a countable set of items.

In English we also say:

• cardboard boxes
• not usually cardboards boxes

Hebrew works similarly. קרטון stays singular because it means the material cardboard.

So ארגזי קרטון literally means boxes of cardboard.

Because this is another construct chain.

The noun עגלה becomes עגלת when followed by another noun:

• עגלה = cart / wagon
• עגלת משא = cargo cart / freight cart

So עגלת is the construct form of עגלה.

This is parallel to:

• ארגזים → ארגזי
• עגלה → עגלת

In a construct chain, the second noun can carry the definiteness for the whole phrase.

So:

• עגלת משא = a freight cart
• עגלת המשא = the freight cart

Even though ה־ appears only on משא, the whole phrase becomes definite.

This is an important rule in Hebrew: in construct phrases, you normally do not put ה־ on the first noun.

ליד means next to, beside, or near.

In this sentence, it introduces location:

• ליד עגלת המשא = next to the freight cart

It is a very common preposition in everyday Hebrew.

The sentence uses a very common Hebrew order:

• subject: אנחנו
• verb: עורמים
• object: ארגזי קרטון
• place phrase: ליד עגלת המשא

So the pattern is basically:

We + are stacking + cardboard boxes + next to the freight cart

Hebrew can move parts around for emphasis, but this order is natural and straightforward.

Literally, it is something like the cart of the load/freight.

• עגלה = cart / wagon
• משא = load, burden, freight, cargo

Together, עגלת המשא means a cart used for carrying loads, so in natural English it might be:

• the freight cart
• the cargo cart
• the hand truck / wagon for carrying loads

The best translation depends on context.

The verb comes from the root ע-ר-ם, which is related to piling up or stacking.

The dictionary form is לערום = to stack / to pile up.

From that verb:

• עורם = he is stacking
• עורמים = they are stacking / we are stacking / stacking (masculine plural, depending on context)

So learning the root helps you recognize related forms more easily.
