Questions & Answers about Tempo je rychlé.
Because tempo is a neuter singular noun, and adjectives in Czech have to agree with the noun they describe.
The adjective rychlý changes its ending depending on gender:
- rychlý = masculine
- rychlá = feminine
- rychlé = neuter
So:
- rychlý vlak = a fast train
- rychlá hudba = fast music
- rychlé tempo = fast tempo
In Tempo je rychlé, the adjective is still agreeing with tempo, so it must be rychlé.
A very common clue in Czech is the ending of the noun. Nouns ending in -o are often neuter, and tempo follows that pattern.
So:
- to tempo = that tempo
You can also see the neuter agreement in other words used with it:
- to rychlé tempo
- to tempo je rychlé
Not every noun can be guessed perfectly just from its ending, but -o is a strong sign of neuter gender.
