Questions & Answers about 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.
