Questions & Answers about Porada začne v deset.
Porada is the subject of the sentence: it is the thing that will start.
It is in the nominative singular form.
The noun porada is feminine, so the verb form agrees with a 3rd person singular subject.
So the structure is basically:
- Porada = the meeting / briefing / consultation
- začne = will start
- v deset = at ten
Začne is the 3rd person singular future form of the verb začít, which means to begin / to start.
A useful way to think about it:
- začít is a perfective verb
- perfective verbs in Czech usually express a completed single event or the starting point of an action
- because of that, the present-looking form of a perfective verb usually has future meaning
So začne does not mean starts right now in a present sense. Here it means will start.
