Is "mit" accusative of "mi"? ("Mit csinál a férfi?")
Yes. Similarly, "kit" is the accusative of "ki;" you might see that.
Kit = whom
Thank you!) It is strange that they used in lessons grammar that haven't been explained in "tips and notes". I just noticed that it is similar to Estonian: mi = mis; mit = mida.
Yes, but in Estonian we can say "Mis see on?", but not "Mida see on?".
Isn't it the same in Hungarian?
I don't speak Estonian (yet ;) ), but Google Translate told me "Mis see on?" means "What is it?". If that's the case, yup, it's the same in Hungarian.
