If you haven’t been told this information yet, this might be not a very good news for you: Pronouns have cases, too. For example: ona (she), ní, ji, jí, on (he), něho, ho, jeho, němu, mu, atd. But dont worry, I will help you today with a couple of pronouns. But firstly a question – what is a pronoun? Its a short word that replaces the noun. And since it is a short word, it is coming on the second position in Czech sentence. And because it replaces the noun, thats the reason why we call it pro-noun or zájmeno. It comes za jméno (instead of the noun).
When replacing the noun, one important thing: you need to know its gender. Because we use masculin and feminine. So if you want to sound as a Czech person, think of the gender. Example is better that the theory, right. In English “Do you like that pullover or jumper? Yes, I do like it.” In Czech: Yes, I like him. Or: “Can you hear that song? Yeah, I can hear her.” I know pullover and song are things but Czech things are alive and have genders
