Here is the additional page about articles in Novoslovnica. You should know that unlike English, Novoslovnica has three definite articles and no indefinite one. They are derived from demonstrative pronouns (like English "THE"<"THAT"). Also it has the difference in place where you should put an article. In English it's the place before noun construction (N or ADJ+N). In Novoslovnica you should put it IN the end of the word you'are talking about. We divide them usually by hyphen from the main word, but you can write without it too. Let's look at them all.
This article is used when you're speaking about something you've already said, but we can't see the object. For example, if we spoke about the house you used to live in and then mention it again, you should use this article.
This article is used when you're speaking about something you've already said and this object is close to us (in the field of view). For example, if we talk about the cow that have just given to us a big bucket of milk and we'are staying next to the cow, we should use this article.
The last one is used when we'are speaking about something you've already said and this object is in our field of view, but it's rather far from us. For example, we'are talking about the village that is ahead, but still rather far from us. And then we mention it again - we should use this article.
Using of articles is your own choice. Using of article is a total equivalent of using demonstrative pronouns before the noun construction. You choose by yourself what's better or more comfortable for you and your listener to use in concrete case.
We used "//" symbol to show that articles depend on the gender of the word they are using with. So, with masculine we use ův, ůn, ůt; with feminine - va, na, ta and with neutral - vo, no and to.
