How would this ever be used?
Also accepted (and certainly more often used in real life): he, this, that.
I thought "člověk" could only be used for "person", but it can also be used instead of "muž"?
Človek can also mean "man," but muž and člověk are not interchangeable in every context. The course seems to translate človek more often as "person" than as "man," but that's just my impression.
člověk ^ ;-)
Sometimes one's paws are muddy... :-)
why would you use to, a neuter word. When you also use dobrý, a masculine word?
This is the well known "to je/je to" pattern used for all genders.
I think "Ten je" would actually be more like "That one is" here.
