The “v” in polévka sounds like an “s.” Is this correct. If so, can someone explain why.
VK is a group of consonants. The pronunciation is therefore determined by the second consonant. And because K is an unvoiced consonant, V is also changed to its unvoiced partner - F. Proper pronunciation should be "poléfka" (it is also kind of what the tts says, or at least I hear it).
They are different, and they're often used to distinguish one thing from another, when those two things are similar. As an example of this usage....
There are two guys standing in front of you. You point to one of them and say, "THIS man just won a billion dollars!!" Next, you point to the other one and say, "THAT man is about to go to jail for robbing a bank." So... would you rather be "this" man or "that" one? :-)
when do I use "polevka" and when "polevku" ?
sorry, I don't have any accents on my keyboard.
Polévka is the nominative case used for subjects, polévku is the accusative case often used for direct objects. Please review the Tips and notes or any other introductory material about grammatical cases (namely these two cases at this stage).
