Why Study Latin?

Children at the Lake Worth Classical Academy will begin studying Latin in fourth grade. Why teach children a dead language? Great question! Here's a great answer:
 

I will say at once, quite firmly, that the best grounding for education is the Latin grammar. I say this, not because Latin is traditional and medieval, but simply because even a rudimentary knowledge of Latin cuts down the labor and pains of learning almost any other subject by at least 50 percent. It is the key to the vocabulary and structure of all the Romance languages and to the structure of all the Teutonic languages, as well as to the technical vocabulary of all the sciences and to the literature of the entire Mediterranean civilization, together with all its historical documents.
