Actually it's dead because there's no changes in grammar or words. It's still spoken by the Pope and the gang at the Vatican.SilentCom said:Romantic languages such as english, french, german, and spanish are based from latin therefore learning latin will make it much more easy to learn the other languages. Also, if you find any really old texts in latin, you could read them. It's a dead language in the sense that people don't speak it, but the history is still there waiting to be uncovered.
Latin is VERY useful for biologists and historians. It's a dead language so you know nothing will change. vulpes vulpes still means the same now as it did before, and anyone can find out what it is without too much trouble (though some will already know).
