Importance of Latin words and expression

Why Latin terms and expressions are important?

Before I tell you the importance of Latin I would like to acknowledge you that Latin is a regarded as a ‘dead’ language because it is not used as a main language in any nation and we do not use it in day-to-day communications.

But however, Latin remains very much alive as a highly significant language, especially in business, technical definitions, law, education, grammar, and science, etc.

Although Latin is not a main language of any country, but still Latin is being taught to millions of students around the world, and will continue to be for a very long time to come.

The fundamental reason is:

Latin is the main and most recent root language for many major languages in the world.

Also, for centuries, in fact for more than two millennium, Latin has been a main language of scholarship and academia.

More specifically:

For many centuries Latin has been used widely in law and law is crucial to governance and leadership, society and civilization, diplomacy and international relations, business, trade, and commerce, finance, the military etc.

Latin is obviously vital for the operation of many fundamental professions and disciplines, and for the rest of us, Latin remains fascinating and helpful in understanding our day-to-day language, especially the Latin expressions and terminology which survive and arise in business, technical definitions, law, education, grammar, and science, etc.

Here are few examples of Latin terms which are used frequently in English, including some extremely common abbreviations:
