Did you know how much of the English language comes from Latin? Many English words share Latin roots with the Romance languages such as Spanish, French and Italian, so it's often easy to decode a new word by considering the bit of Latin you know. For example, the Latin root "aud" means to hear, which forms the basis for the English words "auditorium" and "audience," both of which have to do with listening.
Some Latin comes to English in more than roots of words. There are many phrases used wholesale from the original Latin. It pays to know these popular pieces of the Latin language, as you'll see them regularly in English in a variety of situations.
This is just a sampling of the very numerous Latin phrases still used in the English language. Many are legal terms, but you'll find others in everyday use, too. Keep your eyes open, and you're sure to notice that Latin is all around you, even though it's not spoken on a daily basis any more.
