Obuv je čistá.

In Czech, obuv is a singular collective noun. It means footwear as a category, not necessarily one single shoe.

So Czech treats it grammatically as singular:

• Obuv je čistá. = The footwear is clean.

That is why the verb is je and the adjective is čistá in singular form.

If you wanted to talk about actual shoes as separate items, you would more often use boty, which is plural:

• Boty jsou čisté. = The shoes are clean.

Obuv is feminine.

One clue is the adjective:

• čistá is the feminine singular form of čistý.

You cannot always tell gender just from the noun ending, because obuv ends in a consonant, which often suggests masculine in Czech, but not always. Some feminine nouns also end in a consonant, and obuv is one of them.

So this is a word whose gender you mainly need to learn with the noun:

• ta obuv = that footwear

The adjective must agree with the noun in gender, number, and case.

Here:

• obuv = feminine, singular, nominative
• so the adjective must also be feminine, singular, nominative:
• čistá

Compare:

• čistý = masculine singular
• čistá = feminine singular
• čisté = neuter singular or plural in some contexts

So Obuv je čistá is correct because obuv is feminine singular.

It is in the nominative case.

This sentence is a basic subject + verb + adjective sentence:

• Obuv = the subject
• je = is
• čistá = clean

Subjects are normally in the nominative, so obuv is nominative here.

Also, the adjective čistá matches the nominative feminine singular form.

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

Since obuv is grammatically singular, Czech uses:

• je = is

So:

• Obuv je čistá. = Footwear is clean.

Compare:

• Boty jsou čisté. = Shoes are clean.

Because boty is plural, the verb changes to jsou.

In normal standard Czech, you usually keep je in this kind of sentence.

So the normal sentence is:

• Obuv je čistá.

In some special contexts, especially headlines, labels, notes, or very informal speech, Czech may omit the verb:

• Obuv čistá

But that sounds incomplete in ordinary neutral speech. For a learner, the safe and correct full sentence is:

• Obuv je čistá.

A rough pronunciation guide is:

• obuv ≈ OH-boof
• je ≈ ye
• čistá ≈ CHEES-taa

A few important details:

• č sounds like ch in chocolate
• j in je sounds like English y
• á is a long vowel, so čistá ends with a longer aa
• final v in obuv is often pronounced closer to f in actual speech, so it can sound like obuf

Yes, but it is a bit more general and sometimes slightly more formal or commercial than everyday boty.

You often see obuv in:

• shop signs
• product descriptions
• official or written language

Examples:

• dětská obuv = children’s footwear
• zimní obuv = winter footwear

In everyday conversation, if you mean shoes, people often say:

• boty

So:

• Obuv je čistá. sounds fine, but a bit more like the footwear is clean
• Boty jsou čisté. sounds more like the shoes are clean

Czech has no articles like English a or the.

So obuv can mean:

• footwear
• the footwear
• some footwear

The exact meaning depends on context.

That means:

• Obuv je čistá. could mean The footwear is clean or simply Footwear is clean, depending on the situation.

This is completely normal in Czech.

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

The neutral, most ordinary order is:

• Obuv je čistá.

You can also say:

• Čistá je obuv.

But that sounds marked or emphatic, as if you are contrasting it with something else:

• Čistá je obuv, ale taška ne. = The footwear is clean, but the bag isn’t.

So for a normal plain statement, Obuv je čistá is the best choice.

Yes. Ta obuv je čistá is grammatical.

Here ta means something like that or sometimes functions similarly to the in context:

• Ta obuv je čistá. = That footwear is clean.

But Czech does not need a determiner in a basic sentence, so:

• Obuv je čistá.

is already complete and natural.

Use ta only if you want to point to specific footwear or add emphasis.
