Why isn't "Bisi sȳri zentyssy issi" correct as well? Supposedly there shouldn't be any difference between "these" and "those" when simply choosing a word without a target translation?
The sentence to translate is "Those ones are the good guests." When we use "these", we refer to something close/next to us. When we use "those", we refer to something that is further away from us.
When we want to say that/those, we have to use one of the following:
Kony (singular inan.), Koni (plural inan.)
Bony (singular anim.), Boni (plural anim.)
Since the guests are animate and there are more than one, we use "Boni". Cheers!
