Szkolenie trwa do południa.

Szkolenie usually means training, a training session, or sometimes a workshop depending on context.

It is a noun, not a verb. So the sentence is built around the training as the subject.

A related verb is szkolić / szkolić się, meaning to train or to undergo training.

Trwa means lasts, continues, or is going on.

Its dictionary form is trwać.

So in this sentence, trwa tells you that the training is continuing for a certain period of time.

Examples:

• Film trwa dwie godziny. — The film lasts two hours.
• Spotkanie trwa dalej. — The meeting is still going on.

Because Polish normally uses a simple verb here, just like English often says the meeting lasts rather than the meeting is lasting.

Trwać is the natural verb for duration.
So Szkolenie trwa do południa is the normal, idiomatic way to say it.

Using something like jest trwające would sound unnatural in everyday Polish.

Because it is the subject of the sentence, so it is in the nominative case.

The basic structure is:

Szkolenie + trwa + do południa
subject + verb + time expression

Szkolenie is a neuter noun, and in the nominative singular its form is szkolenie.

Do południa means until noon, up to noon, or in some contexts before noon.

In this sentence, the most natural meaning is until noon.

So it gives the endpoint of the training’s duration.

Because the preposition do normally requires the genitive case.

The base form is:

• południe — noon, midday

After do, it becomes:

• do południa — until noon

This is a very common pattern in Polish:

• do domu — to home / homeward
• do pracy — to work
• do wieczora — until evening
• do rana — until morning

So do + genitive is the key rule here.

Not always with mathematical precision.

In many contexts, do południa is understood as until noon or more generally before the afternoon. In everyday speech, it can sometimes be a little flexible.

But in a sentence like Szkolenie trwa do południa, the default reading is that the training ends around noon.

Yes. Polish word order is more flexible than English, although Szkolenie trwa do południa is the most neutral order.

Other possible orders include:

• Do południa trwa szkolenie.
• Szkolenie do południa trwa. — possible, but less neutral

Changing the order usually changes emphasis, not the core meaning.

For example:

• Do południa trwa szkolenie. puts more focus on until noon.

Because Polish does not have articles like a or the.

So szkolenie can mean:

• a training session
• the training session

Which one is meant depends on context.

That is completely normal in Polish.

Trwać is imperfective.

That makes sense, because it describes an ongoing state or duration rather than a completed action.

In this sentence, that is exactly what you want: the training is lasting until a certain point.

A rough English-friendly guide is:

shko-LE-nyeh trvah do po-WOOD-nya

A few helpful pronunciation notes:

• sz sounds like English sh
• ł sounds like English w
• nie at the end of szkolenie sounds roughly like nye
• trwa begins with a consonant cluster that may feel difficult at first
• dnia in południa sounds roughly like d-nya

If you want to sound more natural, pay attention to stress:

• szkoLEnie
• poŁUDnia

Polish stress is usually on the second-to-last syllable.

Sometimes, yes, but the meaning changes a bit.

• szkolenie = training session, professional training, instruction
• kurs = course, often something longer or more structured
• trening = training/practice, often physical or athletic

So if this is workplace or professional training, szkolenie is often the best choice.
