Questions & Answers about Šatna je malá.
Because the adjective has to agree with the noun.
Since šatna is:
- feminine
- singular
- nominative
the adjective must also be:
- feminine
- singular
- nominative
So:
- masculine: malý
- feminine: malá
- neuter: malé
That is one of the most important patterns in Czech grammar: adjectives change their endings to match the noun.
