Przesyłka zaginęła.

Because przesyłka is a feminine singular noun, and the Polish past tense agrees with the subject in gender and number.

• on type nouns would take -ł in the masculine singular past
• ona type nouns take -ła in the feminine singular past
• ono type nouns take -ło in the neuter singular past

So:

• list zaginął = the letter went missing
• przesyłka zaginęła = the shipment/package went missing
• pismo zaginęło = the document went missing

That -ęła ending is exactly what you expect with a feminine noun like przesyłka.

The dictionary form is zaginąć.

That is the infinitive, meaning something like to go missing, to become lost, or to disappear in the sense of being unaccounted for.

In the sentence:

• zaginęła = past tense, feminine singular
• dictionary form: zaginąć

So if you look it up in a dictionary, search for zaginąć, not zaginęła.

It is in the nominative singular.

That is because przesyłka is the subject of the sentence — it is the thing that went missing.

You can tell it is nominative because the sentence structure is basically:

• Przesyłka = the shipment/package
• zaginęła = went missing

So this is a very straightforward subject + verb sentence.

Not exactly.

Przesyłka is a bit broader and often sounds more official, postal, or logistics-related. It can mean:

• shipment
• consignment
• parcel
• delivery item

Paczka is more everyday and often means a package/parcel in ordinary speech.

So:

• Przesyłka zaginęła sounds natural in tracking, customer service, delivery notifications, or formal complaints.
• Paczka zaginęła is also natural, but feels a little more everyday and less official.

Because zaginąć and zgubić are used differently.

zaginąć means that something went missing or became lost. It focuses on the item itself and what happened to it.

• Przesyłka zaginęła = the shipment went missing

zgubić means to lose something and normally requires a person or agent.

• Zgubiłem klucze = I lost the keys
• Firma zgubiła dokumenty = the company lost the documents

So if you want to say that the package itself is missing, zaginęła is a natural choice. If you want to say that someone lost it, you would use zgubić.

Yes, zaginąć is perfective, and that matters.

The perfective verb presents the event as a completed whole: the package has reached the state of being missing.

So Przesyłka zaginęła sounds like:

• the shipment went missing
• the shipment got lost

It refers to a completed event in the past.

This is why the sentence works well for a report or outcome. It is not describing an ongoing process; it is stating the result.

Yes, you can.

Polish word order is more flexible than English because endings carry a lot of grammatical information.

Both of these are grammatical:

• Przesyłka zaginęła.
• Zaginęła przesyłka.

The difference is mainly in focus or style.

• Przesyłka zaginęła is the most neutral: topic first, then what happened.
• Zaginęła przesyłka puts more attention on the fact that something went missing, or can sound a little more dramatic or report-like.

For a learner, the first version is the safest neutral pattern.

Because Polish does not have articles like English a or the.

So przesyłka can mean:

• a shipment
• the shipment

The exact meaning depends on context.

That is completely normal in Polish. You do not need to add anything to express the.

A rough English-friendly approximation is:

pshe-SIW-ka za-gee-NEH-wa

A few useful details:

• prz at the start sounds like a Polish consonant cluster, roughly like psh to English ears
• y in przesyłka is not exactly English ee or ih; it is a distinct Polish vowel
• ł sounds like English w
• ę in zaginęła is often not pronounced as a full nasal vowel in careful textbook style; before ł, in normal speech it usually comes out close to e plus a slight w glide, so -nęła sounds roughly like -NEH-wa

You do not need perfect phonetics at first; pshe-SIW-ka za-gee-NEH-wa is a good starting point.

The verb zaginąć can be used for both people and things.

For example:

• Dziecko zaginęło. = The child went missing.
• Dokument zaginął. = The document went missing.
• Przesyłka zaginęła. = The shipment went missing.

With people, it often has a serious sense: missing / unaccounted for.

With things, it often appears in formal or official language, especially with mail, documents, evidence, or shipments.

Yes, absolutely.

Przesyłka zaginęła. is a complete, natural Polish sentence. It contains:

• a subject: przesyłka
