Learn Polish: Czy twoja przesyłka z Polski jest anulowana? - Is your parcel from Poland cancelled?

jest anulowana uses the verb być (to be) to describe a resulting state: the parcel is currently in a cancelled status. If you used została anulowana, you would be emphasizing the dynamic action or event of someone cancelling it in the past. Because we just care about its current condition here, we use the stative passive voice.

Why does the word anulowana end with an -a?

In the passive voice, the participle acts like an adjective. It must match the gender and number of the subject. Since the subject here is przesyłka, which is a feminine noun, the participle takes the feminine singular ending -a.

How do we build the passive participle anulowana from the verb anulować?

For most verbs ending in -ować, you drop the final -ć and add the passive endings -ny, -na, or -ne. Since we need the feminine form here, we add -na to the stem anulowa-, giving us anulowana.

Why does the sentence use z Polski instead of z Polska?
