Questions & Answers about Ta pieczątka jest czerwona, a potwierdzenie dostanę jutro rano.

Why is it ta pieczątka and not ten pieczątka or to pieczątka?

Because pieczątka is a feminine noun in Polish. Demonstratives must agree with the noun’s gender:

• ten = masculine
• ta = feminine
• to = neuter

So:

• ta pieczątka = this stamp / this seal

This is the same kind of agreement you also see in the adjective czerwona.

Why does czerwona end in -a?

Because adjectives in Polish must agree with the noun they describe in gender, number, and case.

Here, pieczątka is:

• feminine
• singular
• nominative

So the adjective also takes the feminine singular nominative form:

• masculine: czerwony
• feminine: czerwona
• neuter: czerwone

That is why we get:

• Ta pieczątka jest czerwona.

What exactly does pieczątka mean here?

Pieczątka usually means a stamp, rubber stamp, or official seal/impression, not a postage stamp on a letter.

So in this sentence it most likely refers to an official stamp or mark on a document.

If you meant a postage stamp, the usual word would be znaczek.
