Thanks a lot for all the effort you spend on this course! Now I do have voice sound and I can study on. I made a typo: ‘vikend’ instead of ‘víkend’ and the program even recognised that! Now I can study Czech with more confidence. I know I will be corrected on ALL my mistakes. And I can study pronunciation. Thanks again
Hezký and dobrý have different meanings they're like Nice and Good in English, they mean similar but are used in different situations.
Is it possible to say "Dobrý vikend"? Or is "weekend" different from "dén" and "vecer" and "ráno" etc.?
No. You cannot say "dobrý víkend". Not sure why. Maybe because Dobrý den, večer, ráno are greetings while Hezký víkend is something you wish to somebody when you are parting ways. You can even say "Have a nice day" - Hezký den when you are parting ways with somebody.
It is not, "Hezký víkend" is the only appropriate form.
But of course, you can say "Byl to dobrý víkend" (It was a good weekend).
Well.... You can.. The only reason, why "dobrý víkend" is somehow unthinkable, is .. habit. So you can try to change the habit and maybe people will follow you and in next years and perhaps centuries your invention will prevail. "Dobrý víkend" is completely correct, but no one would ever use it. And it is true that "Hezký víkend" is maybe little bit less standardized and less rigid greeting than for example "dobrý den", so it is not so essential to learn. For example you could say "Užijte si víkend" (Enjoy your weekend) - this is even more frequent (IMHO).
"weekend" is not allowed in Czech? It must be víkend? In Polish, "weekend" is weekend
No, you hear it very well. In Czech pronounciation there is a rule called "voicing assimilation". If there is a consonanat folowed by another consonant it changes its voicing to match the folowing. zk: "k" is unvoiced so z (voiced) changes to s (unvoiced equivalent)
