Questions & Answers about Tato místnost je vhodná pro tuto činnost.

Why does the sentence use tato in one place and tuto in another?

Because they are the same demonstrative pronoun ten / ta / to in different cases.

• tato místnost = this room
  
  • místnost is the subject, so it is in the nominative
• pro tuto činnost = for this activity
  • after pro, Czech uses the accusative

So:

• tato = feminine singular nominative
• tuto = feminine singular accusative

Both místnost and činnost are feminine singular nouns, but they play different roles in the sentence, so the forms differ.

Why is vhodná ending in -á?

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

Here, vhodná describes místnost:

• místnost = feminine singular
• it is in the nominative
• so the adjective must also be feminine singular nominative

That is why you get:

• masculine: vhodný
• feminine: vhodná
• neuter: vhodné

So vhodná matches místnost.
