Το μικροαντικείμενο είναι στο κουτί, στο σημείο συλλογής.

Because μικροαντικείμενο is a neuter singular noun, and το is the neuter singular definite article. In this sentence, το μικροαντικείμενο is the subject, so the article is in the nominative form.

Greek uses articles very regularly, often in places where English might be a little looser.

The written accent mark shows you the stressed syllable:

• μικροαντικείμενο → stress on -κεί-
• κουτί → stress on -τί
• σημείο → stress on -μεί-
• συλλογής → stress on -γής

So if you are reading aloud, the accents are very important. Greek spelling usually tells you exactly where the stress goes.

Στο is a contraction of σε + το.

• σε = a preposition that can mean in, at, on, or to
• το = the for a neuter singular noun

So:

• στο κουτί = σε το κουτί
• στο σημείο = σε το σημείο

In normal Greek, people use the contracted form στο, not the full σε το.

Because the sentence has two location phrases:

• στο κουτί
• στο σημείο συλλογής

Greek repeats the preposition/article combination for each phrase, just as English would repeat in the or at the if needed.

So the structure is essentially:

• the small object
• is
• in the box
• at the collection point

In Modern Greek, σε normally takes the accusative case. So after στο, the noun is in the accusative.

However, κουτί is a neuter noun, and for many neuter nouns the nominative and accusative singular look exactly the same. That is why you do not see any change in the form.

So even though the case changes grammatically, the word itself still looks like κουτί.

Because συλλογής is in the genitive singular. This is a very common Greek pattern:

• noun + genitive noun

So:

• σημείο συλλογής = literally point of collection

English often uses a noun directly before another noun, as in collection point. Greek often expresses that relationship with the genitive instead.

That is why συλλογή changes to συλλογής.

Because συλλογής is functioning as a descriptive genitive: it tells you what kind of point it is.

So σημείο συλλογής means something like:

• collection point
• literally point of collection

If you added an article, for example της συλλογής, the meaning would shift more toward the point of the collection, which is a different idea.

The comma separates the two location expressions:

• στο κουτί
• στο σημείο συλλογής

It suggests that the second phrase adds extra information or further specifies the location. In context, it can sound a bit like:

• in the box, at the collection point

Depending on style and context, punctuation in Greek can sometimes vary, so you may not always see the comma used in exactly the same way.

No. Greek word order is more flexible than English word order. The version you have is a neutral, straightforward order:

• subject
• verb
• location phrases

You can move parts of the sentence for emphasis, but that changes the focus. For example, putting στο κουτί first would emphasize the location more strongly.

So the given order is natural, but not the only possible one.

Yes. Βρίσκεται is often used for location and can sound a bit more precise or formal.

So you could also say:

Το μικροαντικείμενο βρίσκεται στο κουτί, στο σημείο συλλογής.

Both are correct, but:

• είναι = simpler, very common
• βρίσκεται = more explicitly is located

In instructions, descriptions, or formal writing, βρίσκεται is especially common.
