Another result of learning Latin is that, besides helping our English, we can gain a foundation for all language study.  Ninety to ninety-five percent of Spanish, French, Italian, Portuguese, and Romanian vocabulary is derived from Latin.  On this diagram you can see, by looking at the red part of each language, how much of its vocabulary comes from Latin.

So knowing Latin will make learning those languages much easier.

In addition, language learning principles and grammar skills acquired in the study of Latin transfer to the learning of non-Romance languages as well.  How to conjugate a verb, what a perfect passive participle is, what a reflexives pronoun is used for…all these grammar goodies are found in every language. So think if it, with a foundation in Latin, one can become a language learning machine!
