Questions & Answers about Ta spódnica pasuje do tej bluzki.

Why is it ta spódnica but tej bluzki?

Because the two noun phrases are in different cases.

• ta spódnica = this skirt in the nominative case, because it is the subject of the sentence
• do tej bluzki = to/with this blouse after the preposition do, which requires the genitive case

So:

• ta is the nominative feminine singular form of this
• tej is the genitive feminine singular form of this

And the noun changes too:

• bluzka → bluzki in the genitive
