Brzda je hlasitá.

Because brzda is a feminine singular noun, and Czech adjectives must agree with the noun they describe.

• brzda = feminine singular
• hlasitý = the basic dictionary form of the adjective, usually given in the masculine singular
• to match brzda, it changes to hlasitá

So:

• hlasitý = loud/noisy (masculine)
• hlasitá = loud/noisy (feminine)
• hlasité = loud/noisy (neuter)

This is one of the most important patterns in Czech grammar: adjectives agree with the noun in gender, number, and case.

A very common clue is the ending -a. Many Czech nouns ending in -a are feminine, and brzda is one of them.

So learners often recognize it like this:

• nouns ending in -a → often feminine
• therefore the adjective also takes a feminine ending

Of course, there are exceptions in Czech, but brzda is straightforwardly feminine.

It is in the nominative singular.

This sentence has the structure:

• Brzda = subject
• je = is
• hlasitá = predicate adjective

In Czech, the subject of the sentence is normally in the nominative case, so brzda stays in its basic form here.

Je is the 3rd person singular form of the verb být (to be).

So:

• já jsem = I am
• ty jsi = you are
• on/ona/ono je = he/she/it is

Since brzda is a singular noun, Czech uses je:

• Brzda je hlasitá. = The brake is loud.

Unlike Russian, Czech normally does use the present-tense form of to be in sentences like this.

In normal standard Czech, no — you should keep it:

• Brzda je hlasitá.

Leaving it out would sound incomplete or nonstandard in ordinary speech and writing.

So for learners, the safe rule is:

• in present-tense sentences with to be, Czech usually keeps the verb

It can often be translated as loud, and depending on context also something like noisy.

With brzda, English might say:

• The brake is loud
• The brake is noisy

The Czech adjective hlasitý / hlasitá / hlasité is connected with sound volume or something making a noticeable sound.

A nearby adjective you may also see is hlučný / hlučná / hlučné, which often means noisy in a broader sense. In many contexts the two overlap, but hlasitý more directly suggests loud-sounding.

A rough English-friendly pronunciation is:

BRZ-da ye HLA-si-taa

A few notes:

• brzda starts with a consonant cluster brz-, which may feel difficult at first
• r in Czech is a rolled or tapped r
• z is pronounced like the z in zoo
• j in je sounds like English y, so je sounds roughly like ye
• á is a long vowel, so the last syllable of hlasitá is held a bit longer: -taa

Stress in Czech is usually on the first syllable of the word:

• BRZ-da
• HLA-si-tá

Yes, Czech word order is more flexible than English, because case endings carry a lot of grammatical information.

The neutral, ordinary order is:

• Brzda je hlasitá.

But you could also say:

• Hlasitá je brzda.

That version sounds more marked or emphatic, something like:

• It’s the brake that is loud
• The brake is loud (with emphasis on loud)

So both are possible, but the original sentence is the most neutral one for a beginner to learn first.

The dictionary forms are:

• brzda = brake
• být = to be
• hlasitý = loud

This is important because Czech dictionaries usually list:

• nouns in the nominative singular
• verbs in the infinitive
• adjectives in the masculine singular form

So even though the sentence has hlasitá, you would normally look it up under hlasitý.

By itself, brzda just means brake, so the exact kind depends on context.

It could refer to:

• a car brake
• a bike brake
• a machine brake
• another braking mechanism

If the surrounding conversation is about a car, then brzda will naturally be understood as a car brake. Czech often relies on context just like English does.

The plural would be:

• Brzdy jsou hlasité. = The brakes are loud.

Here several things change:

• brzda → brzdy (plural noun)
• je → jsou (plural form of to be)
• hlasitá → hlasité (adjective agreeing with a plural feminine noun in nominative)

So this sentence is a good example of agreement across the whole sentence.
