In fact, medical and legal vocabulary can easily be derived from Latin and Greek roots to this day. Let us begin our exploration of words borrowed into English with an examination of the impact of Latin and Greek. Here is a series of PIE maps showing how the dialects of PIE spread farther and farther apart, developing into distinct languages in the process. Even though Latin and Greek developed into the Romance languages and Modern Greek, respectively, their literature continued to have a profound effect on the peoples of Europe. All of the modern languages borrow words and stems from both languages.
Borrowing is another source of words.
Here are some of the words and roots borrowed into English from Latin words. Greek is a particularly rich source of medical terms. Take a look at the following list to get an idea of the role Greek words and roots play in the English language. The important point is that the meanings of these words are what they are because of the original meanings of the Greek roots in them. Those roots are still being used today by doctors and others to create new English words.
