Potrubí je poškozené.

Potrubí means pipework, piping, pipeline, or a system of pipes. It usually refers to the pipe system as a whole, not just one small individual pipe.

So depending on context, Potrubí je poškozené. could be understood as:

• The piping is damaged.
• The pipeline is damaged.
• The pipework is damaged.

If you wanted to talk about a single physical pipe, Czech would more often use trubka or roura, depending on context.

Potrubí is neuter singular.

That matters because the adjective must agree with it:

• masculine: poškozený
• feminine: poškozená
• neuter: poškozené

Here we have poškozené, so it matches a neuter singular noun.

A useful thing to know is that many Czech nouns ending in -í are neuter, though you still need to learn them individually.

In this sentence, potrubí is singular.

That can be confusing because in English, words like piping or pipework don’t feel strongly singular in the same way. But in Czech, potrubí behaves grammatically as a singular neuter noun, which is why the verb is je (is) and not jsou (are).

So:

• Potrubí je poškozené. = The piping is damaged.

Not:

• Potrubí jsou poškozené. unless you were talking about multiple separate pipe systems in some special context.

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

So here it simply means is:

• potrubí = the piping / pipeline
• je = is
• poškozené = damaged

So the structure is very straightforward:

subject + form of “to be” + adjective

Because it agrees with potrubí, which is neuter singular.

Czech adjectives change their endings to match the noun’s:

• poškozený = masculine singular
• poškozená = feminine singular
• poškozené = neuter singular

Examples:

• kabel je poškozený = the cable is damaged
• trubka je poškozená = the pipe is damaged
• potrubí je poškozené = the piping is damaged

This agreement is one of the most important things to notice in Czech sentences.

Both are possible, but they are a little different in style and feel.

• Potrubí je poškozené.
  This uses an adjectival form and sounds like a normal descriptive statement: The piping is damaged.

• Potrubí je poškozeno.
  This is a more formal/passive-style expression, often found in reports, technical writing, announcements, or official language.

In everyday speech, poškozené often feels more natural.
In formal written Czech, poškozeno is also very common.

So for a learner, poškozené is an excellent version to know first.

Yes. Czech has no articles like a/an/the, so definiteness is understood from context.

So Potrubí je poškozené. can mean:

• The pipeline is damaged.
• The piping is damaged.
• sometimes A pipeline is damaged.

In real life, context usually makes it clear. In many situations, English would naturally translate it with the.

This is a very common adjustment for English speakers learning Czech: Czech does not mark a/the directly.

Yes, Czech word order is more flexible than English, but the neutral order here is:

Potrubí je poškozené.

That is the most natural basic statement.

You may also see variations for emphasis, for example:

• Poškozené je potrubí.
• Je poškozené potrubí.

But these have a more marked or context-driven feel. For a learner, the normal pattern to use is:

subject + je + adjective

So stick with Potrubí je poškozené. unless you have a reason to emphasize something.

A rough pronunciation guide:

• potrubí ≈ POH-troo-bee
• je ≈ yeh
• poškozené ≈ POSH-ko-zeh-nay

A few details:

• j in Czech is pronounced like English y in yes
• š sounds like English sh
• é is a long e sound

The stress in Czech normally falls on the first syllable of each word:

• POtrubí
• JE
• POškozené

In this sentence, it behaves like an adjective meaning damaged.

Historically and grammatically, it is related to a past passive participle from the verb poškodit (to damage), but for many practical learning purposes, you can treat it like a normal adjective that agrees with the noun.

That is why it changes form:

• poškozený kabel
• poškozená trubka
• poškozené potrubí

So the simplest learner-friendly explanation is:

poškozené = an adjective meaning damaged, matched to a neuter singular noun.

No, in standard Czech, in the present tense, you normally keep the verb je in a sentence like this.

So:

• Potrubí je poškozené. = correct

Leaving it out:

• Potrubí poškozené.

would sound incomplete or nonstandard in ordinary Czech.

This is different from some languages where is/are can be omitted in the present tense. Czech normally keeps it.

The base verb is poškodit, which means to damage.

Related forms:

• poškodit = to damage
• poškozený / poškozená / poškozené = damaged

For example:

• Voda poškodila potrubí. = The water damaged the piping.
• Potrubí je poškozené. = The piping is damaged.

This is useful because once you know the verb, you can recognize many related forms.
