Utírám prach ze stolu.

Utírám is the 1st person singular present form of the imperfective verb utírat.

That means it usually expresses:

• an action happening right now: I am wiping
• or a habitual/repeated action: I wipe / I dust

By contrast, utřu is from the perfective verb utřít, which focuses on the action as completed. Czech often uses imperfective verbs for ongoing actions and perfective verbs for completed ones.

So:

• Utírám prach ze stolu. = I’m wiping dust off the table / I’m dusting the table.
• Utřu prach ze stolu. = I’ll wipe the dust off the table / I’ll remove it completely.

Czech often leaves out subject pronouns because the verb ending already shows who the subject is.

Here, -ám in utírám tells you the subject is I.

So:

• Utírám prach ze stolu. = I’m wiping dust off the table.
• Já utírám prach ze stolu. also means the same thing, but já adds emphasis, like I am the one wiping the dust off the table.

English usually needs the pronoun; Czech often does not.

Prach is normally a mass noun, like English dust, so the singular is the normal form.

In this sentence, prach means dust in general, not separate countable pieces of dust.

So utírám prach is the normal way to say I’m dusting / wiping away dust.

A plural form would be unusual in ordinary usage here.

Here prach is the direct object of the verb utírám, so it is in the accusative case.

However, for an inanimate masculine noun like prach, the accusative singular looks the same as the nominative singular.

So:

• nominative: prach
• accusative: prach

That is why the form does not visibly change, even though its grammatical role has changed.

The basic preposition is z, meaning from/out of/off. But Czech often uses ze instead of z when it is easier to pronounce.

So before some consonant clusters or awkward combinations, z becomes ze.

That is why Czech says:

• ze stolu not
• z stolu

This is mainly a pronunciation-friendly variant.

After the preposition z/ze, Czech uses the genitive case.

The dictionary form is:

• stůl = table

But after z/ze, it changes to the genitive singular:

• ze stolu = from/off the table

So:

• stůl = nominative
• stolu = genitive singular

This is one of the most important things to notice in the sentence: the preposition ze requires the following noun to be in the genitive.

It can correspond to either from the table or off the table in English, depending on context.

In this sentence, the natural English meaning is:

• off the table

That is because dust is being removed from the surface of the table.

So z/ze + genitive often covers meanings that English expresses with from, off, or out of.

Yes. Utírat prach is a normal and common expression.

Literally it means to wipe dust, but in natural English this is often simply to dust.

So:

• Utírám prach ze stolu. can be understood very naturally as
  • I’m wiping dust off the table
  • I’m dusting the table

Both are good translations depending on how literal you want to be.

Yes. Czech word order is more flexible than English word order because case endings show grammatical relationships.

The neutral order here is:

• Utírám prach ze stolu.

But you could also hear:

• Prach utírám ze stolu.
• Ze stolu utírám prach.

These versions shift the emphasis:

• Prach utírám ze stolu. emphasizes the dust
• Ze stolu utírám prach. emphasizes where from

The original sentence is the most straightforward, neutral version.

A simple pronunciation guide is:

Utírám prach ze stolu
oo-TEE-raam prakh ze STO-loo

A few helpful points:

• Czech stress is usually on the first syllable of each word.
• í and á are long vowels.
• ch in prach is like the ch in Scottish loch or German Bach, not like English ch in chair.
• ů in stůl changes in this form to o: stolu.

The dictionary forms are:

• utírat = to wipe
• prach = dust
• z / ze = from, off, out of
• stůl = table

In the sentence:

• utírám is a conjugated verb form from utírat
• stolu is the genitive singular form of stůl

Looking up dictionary forms is useful because Czech words often change shape in actual sentences.

Yes, but it means something slightly different.

• Utírám prach ze stolu. = I’m wiping dust off the table.
• Utírám stůl. = I’m wiping the table.

The second sentence focuses on the table as the object being wiped. The first sentence focuses on the dust being removed.

Both are correct; they just describe the action from different angles.

Ze is a preposition.

Its job is to show a relationship like:

• from
• off
• out of

Prepositions in Czech require specific cases, and z/ze requires the genitive. That is why you get ze stolu, not ze stůl.
