Наклейку «Хрупкое» прикрепили к коробке, а опись вещей проверили.

Because наклейку is the direct object of прикрепили — it is the thing that was attached.

• dictionary form: наклейка
• accusative singular: наклейку

This is a very common pattern in Russian:

• прикрепили наклейку = attached the sticker
• проверили опись = checked the inventory/list

For feminine nouns ending in -а, the accusative singular usually changes to -у.

Хрупкое is the neuter singular form of the adjective хрупкий = fragile.

Here it is being used as the actual text written on the sticker, like a label saying Fragile. Russian often uses an adjective by itself this way on labels, signs, and notices.

So наклейку Хрупкое means something like:

• a sticker with the word Fragile on it

It is neuter because this kind of label text is often treated as a standalone word or as something like an omitted neuter noun such as слово or предупреждение in the background. In practice, learners usually just understand it as “the sticker reading Fragile.”

The quotation marks show that Хрупкое is the exact wording written on the sticker.

So:

• наклейку «Хрупкое» = the sticker labeled Fragile
• literally, the sticker “Fragile”

Russian often uses quotation marks this way for titles, labels, inscriptions, and printed text.

The verb прикрепить often takes к + dative when you attach one thing to another.

So:

• прикрепить к коробке = to attach to the box

Here:

• коробка = box
• к коробке = to the box

The preposition к requires the dative case.

Because it follows the preposition к, and к normally takes the dative.

Forms:

• nominative: коробка
• dative singular: коробке

So:

• к коробке = to the box

This is worth memorizing as a fixed pattern:

• прикрепить что? наклейку
• прикрепить к чему? к коробке

Опись means an inventory, itemized list, or contents list.

вещей is the genitive plural of вещи = things, belongings, items.

So:

• опись вещей = a list of the items / an inventory of belongings

This is a noun + genitive pattern, very common in Russian:

• список гостей = list of guests
• план города = map/plan of the city
• опись вещей = inventory of items

Because опись is followed by a noun in the genitive to show what is being listed.

So:

• опись чего? вещей

This is similar to English inventory of items.

Forms:

• nominative plural: вещи
• genitive plural: вещей

This is a very common Russian pattern called an indefinite-personal construction.

The sentence does not name who did the actions, but the plural past tense implies “they” in the sense of someone / people / the staff / workers.

So:

• прикрепили = they attached / someone attached
• проверили = they checked / someone checked

English often uses the passive or an unspecified subject:

• The sticker was attached...
• They attached the sticker...

Russian often uses this plural verb without an expressed subject instead.

Both прикрепили and проверили are perfective past forms, which present the actions as completed.

That fits the sentence well, because it describes finished actions:

• the sticker got attached
• the inventory got checked

Compare:

• прикрепляли / проверяли = were attaching / were checking, or did it repeatedly
• прикрепили / проверили = attached / checked, completed

А often links two clauses while also creating a mild contrast, separation, or shift of focus. It does not always mean a strong but.

Here it works like:

• The sticker was attached to the box, and the inventory was checked
• with a slight sense that these are two separate actions/items in the process

If you used и, it would sound more like a simple joining of two actions. With а, the sentence feels a little more segmented: one thing happened to the sticker, another to the inventory.

Russian word order is flexible. Starting with Наклейку and опись вещей puts attention on those items.

So the sentence is structured roughly like:

• As for the sticker “Fragile”, they attached it to the box, and as for the inventory, they checked it.

This kind of word order is natural when the speaker wants to highlight the objects or present them as the main topics.

A more neutral order might be:

• К коробке прикрепили наклейку «Хрупкое», а опись вещей проверили.

But the original order is perfectly natural too.

Yes. Even though the Russian uses plural verbs with no subject, English often prefers the passive here.

Possible translations:

• The sticker marked “Fragile” was attached to the box, and the inventory of items was checked.
• They attached the “Fragile” sticker to the box and checked the inventory.

Both are reasonable. The Russian structure allows either kind of English translation depending on style.

Not exactly, though they can overlap.

• наклейка = sticker, something adhesive that you stick on
• этикетка = label, tag, product label

In this sentence, наклейка emphasizes the physical sticker that was attached. If you said этикетка, it might sound more like a label in a broader sense, not necessarily focusing on the adhesive sticker itself.

Yes, the structure would be similar.

For example:

• Наклейку «Осторожно» прикрепили к коробке.
• Наклейку «Не кантовать» прикрепили к коробке.

In each case, the quoted word or phrase is the text printed on the sticker. So the grammar pattern stays the same.

The sentence has two parallel parts:

• Наклейку «Хрупкое» прикрепили к коробке
• а опись вещей проверили

Pattern:

1. direct object
2. verb
3. optional prepositional phrase or complement

More specifically:

• что? наклейку
• что сделали? прикрепили
• к чему? к коробке

and then:

• что? опись вещей
• что сделали? проверили

So it is a good example of:

• accusative for direct objects
• dative after к
• genitive after опись
• past plural verb with omitted subject
