Wouldn't "Finitus est" mean "It is finite"?
The short answer is no I don't speak it yet, nor do I know any speakers personally, but would like to learn. I do have a Latin-English dictionary which I tend to flip through from time to time. I thought it would be interesting to have a Latin motto; so I did my best with what I knew. Though I do think grammatical correctness is important here too.
On another note, the only thing preventing me from learning Latin or any other language, is primarily my indecisiveness. Usually I don't know if or where I would use a language, so I never know where to start. In Latins' case, I keep bouncing back and forth; it's a beautiful language and could prove very useful in some academic fields or if I were to go to The Vatican, but I also know you can forget a language if you don't use it consistently. I never understood how polyglots can still be fluent in so many languages regardless whether or not they're using them consistently. In short, I guess what prevents my linguistic ambitions is blurry practicality (if that makes any sense lol).
I see you take interest in linguistics too, refreshing to find people like you. Perhaps we should talk?
Thanks for the suggestion btw! - GrandmasterPaxcel
