Also, to fix my spam earlier.
Most SF books include some amount of slang or some language that is unique to it. I'll use "The Dragonriders of Pern" as an example. They have words and phrases which mean nothing to us until used in context. And they have a lot of it. Runners, gathers, between, so on and so forth.
SF thrives on creating slang and languages to make the setting real.
