Latin Legal Terms Used In The Law And In The Court System, Latin Dictionary! Latin Translations And Definitions!

How do I know what these terms they use in Court mean? I do not speak Latin?

There are many terms used in our legal system that are not in English. This is done to keep the common man ignorant of exactly what a certain Law or phrase means. Knowing that ignorance is no excuse to break the Law, they write the Laws in a language that cannot be understood by the majority of the population.

This is intentionally done to scare you into a plea because those Latin terms are terrifying, and not understandable. By making our Law Systems above the intellect of the common man they retain control over us.

Take the time to educate yourself, if you are in Court and you are not able to understand what is being said, ask questions.

Even if you are represented by a lawyer do not just let things go by that you do not understand. It is very simple, ask the Judge to define and explain everything to you that you do not understand.

Do not be coerced into taking a plea or settling for less then what you think is fair and just.

SPEAK UP! Tell the Judge you have questions concerning Court procedures. If you do not understand what you are being charged with, how could you make an intelligent plea.

History of the Latin Language.

Latin started as a language of farmers and shopkeepers.  It was used primarily in Rome and its territories.

Regardless of its humble beginnings, Latin soon became the language of the higher echelons of civilization.  It quickly spread throughout the complete Western area of the Roman empire.

There are not many languages that have become so successful.  Even more amazing is the spread of the Latin language after the Roman empire fell.

Latin that was verbally spoken, continued to remain stable for a long time.  In fact it never died, it was simply altered through each generation.  The language branched out into many different directions forming the foundation of the Romance languages.

Written Latin remained in use.  It was used as the primary means of communications within churches and schools,  where not only was it spoken but it was also written as well.

Eventually medieval Latin was not a language which belonged to any Nation, its use consisted primarily of the higher educated members of society.
