First, people understand words by context, not by definition. Do not demand that readers memorize definitions, that is a sure fire way to make them put down your story.

Instead, you introduce these in scenes so the context is clear and the word is understood by the reader.

Second, a lot of words is going to take a lot of scenes, and imagination to come up with scenes that fit into the plot for these words to matter.

Sparse is better, do not just invent words because you think they are cool, invent them because you need them.

If virteces are a thing important to the plot, invent a scene where they have to be mentioned. Maybe a lot of them showed up dead, and people are talking about them, and arguing whether virtual reality is a religion or not, or if people are wasting their lives living and working in the virtualverse, or whatever.

So first your new terminology has to matter to the plot in some way, the word must be understandable in context when characters use it, and the word must be used repeatedly the story, and be necessary.

The classic example in Star Trek is the Warp Drive, and Dilithium Crystals.

From the story, from the start, the audience doesn't really know how the warp drive works, or what the hell dilithium crystals are. We learn from context that the Warp drive is FTL, and from context that dilithium crystals power the Warp Drive and cannot be synthesized or transported, unlike virtually everything else.

We learn from context about the Transporter, and how it can go wrong. To this day, I don't think it has ever been explained what "dilithium" is.

Or, for that matter, "gold-pressed latinum", so prized by the Ferengi. We know from context that gold can be synthesized, but apparently gold-pressed latinum cannot be, and thus serves as a form of currency.

The answer is: Do not use (parens) or footnotes, and do not explain the meaning of words (in a pinch, words can be explained by a character to children or a stranger in a strange land, an alien or visitor of some sort).

Words mean what they mean by how they are used, you should strive to create scenes in which the meaning of an author-invented word becomes obvious.

For what it's worth, "verteces" is a bad made up word. It sounds exactly like "vertices", and just looks like a misspelling of that word. I would call people that choose to live in a virtual reality just "virts."

Slang words are generally shorter and easier to pronounce than the words they replace, and unique, they cannot be mistaken for other common words that already exist.

In general, do not make up words that are easily mistaken for existing words, or are difficult to say. New words have to be both obvious and easier to use than the longer version.

That is how texting slang developed. FAIK, OMG, etc. Clear and easy to type.
