Does anybody out there speak/read/write Latin? Why: the wizards in my serial fiction speak an unchanging logical language that I call Rational, but I'm representing as just plain Latin. I'm not so foolish as to have long passages of a language I don't speak (nor do my readers, generally), but the occasional word creeps in and I don't want to look silly. Just as I wouldn't write about horses without checking and double-checking my facts, I was hoping to double check my pseudo-translation. I have actually started some books on learning the language, but for what I have now, I'd prefer to ask a passable expert.
How much: I have exactly three full (three-word) sentences in two hundred pages of writing, and I intend to continue at about that density. In addition, there are people's names (wizards are named by their teachers, and the names are attributes or descriptions - which I know was not the Roman way).
As an example (again, one of three), when a character is freed from years of imprisonment, he screams "Libertas! Liberatus sum!" before switching back to the language of people around him.
If you have a few spare minutes to help out, I'd greatly appreciate not having to trust google translate and my Idiot's Guide To Learning Latin.
Incidentally, I'd be happy to similarly translate mathspeak or programmerspeak if anyone needs it (not just for someone offering to help with my Latin). I can do passable French as well, but I'd need a dictionary to read a page of it.
