While I more than agree with the spirit of your writeup, Gone Jackal (part of which I assume is that there is no excuse for using poor Latin grammar since the rules have long since been written down), I feel I should add this bit of my own pedantry: I don't think you can consider Latin to be a dead language. If the definition of "living language" is one that is still in use (and this definition, though broad, applies), then Latin counts thanks to the Roman Catholic Church, for which Latin is still the primary language. New documents (especially the relatively recent revised catechism) are routinely printed in Latin, and in fact the Church has felt the occasional need to add vocabulary terms which are not currently available. There is now, for example, a Latin term for "bioengineering."
