One of the best ways to improve one's writing, speaking and vocabulary is to take courses in Latin. I took two years of Latin in college and I noticed a massive improvement in my understanding of grammar and writing ability There was a reason why it was taught in schools for so many years after people stopped speaking it. Given many high school and college students' dismal performance in writing and grammar, it would be wise to bring Latin back to schools. This language will never be dead. All Romance languages are directly derived from it as are many words from our own language.
