Latin Words and Phrases Every Man Should Know

What do great men like Benjamin Franklin, Thomas Jefferson, and Theodore Roosevelt all have in common?

They all were proficient in Latin.

From the Middle Ages until about the middle of the 20th century, Latin was a central part of a man’s schooling in the West. Along with logic and rhetoric, grammar (as Latin was then known) was included as part of the Trivium – the foundation of a medieval liberal arts education. From Latin, all scholarship flowed and it was truly the gateway to the life of the mind, as the bulk of scientific, religious, legal, and philosophical literature was written in the language until about the 16th century. To immerse oneself in classical and humanistic studies, Latin was a must.

Grammar schools in Europe and especially England during this time were Latin schools, and the first secondary school established in America by the Puritans was a Latin school as well. But beginning in the 14th century, writers started to use the vernacular in their works, which slowly chipped away at Latin’s central importance in education. This trend for English-language learning accelerated in the 19th century; schools shifted from turning out future clergymen to graduating businessmen who would take their place in an industrializing economy. An emphasis on the liberal arts slowly gave way to what was considered a more practical education in reading, writing, and arithmetic.

While Latin had been dying a slow death for hundreds of years, it still had a strong presence in schools until the middle of the 20th century. Beginning in the 1960s, college students demanded that the curriculum be more open, inclusive, and less Euro-centric. Among their suggested changes was eliminating Latin as a required course for all students. To quell student protests, universities began to slowly phase out the Latin requirement, and because colleges stopped requiring Latin, many high schools in America stopped offering Latin classes, too. Around the same time, the Catholic Church revised its liturgy and permitted priests to lead Mass in vernacular languages instead of Latin, thus eliminating one of the public’s last ties to the ancient language.

While it’s no longer a requirement for a man to know Latin to get ahead in life, it’s still a great subject to study. I had to take classes in Latin as part of my “Letters” major at the University of Oklahoma, and I really enjoyed it. Even if you’re well out of school yourself, there are a myriad of reasons why you should still consider obtaining at least a rudimentary knowledge of the language:

Knowing Latin can improve your English vocabulary. While English is a Germanic language, Latin has strongly influenced it. Most of our prefixes and some of the roots of common English words derive from Latin. By some estimates, 30% of English words derive from the ancient language. By knowing the meaning of these Latin words, if you chance to come across a word you’ve never seen before, you can make an educated guess at what it means. In fact, studies have found that high school students who studied Latin scored a mean of 647 on the SAT verbal exam, compared with the national average of 505.

Knowing Latin can improve your foreign language vocabulary. Much of the commonly spoken Romanic languages like Spanish, French, and Italian derived from Vulgar Latin. You’ll be surprised by the number of Romanic words that are pretty much the same as their Latin counterparts.

Many legal terms are in Latin. Nolo contendere. Mens rea. Caveat emptor. Do you know what those mean? They’re actually common legal terms. While strides have been made to translate legal writing into plain English, you’ll still see old Latin phrases thrown into legal contracts every now and then. To be an educated citizen and consumer, you need to know what these terms mean. If you plan on going to law school, I highly recommend boning up on Latin. You’ll run into it all the time, particularly when reading older case law.

Knowing Latin can give you more insight to history and literature. Latin was the lingua franca of the West for over a thousand years. Consequently, much of our history, science, and great literature was first recorded in Latin. Reading these classics in the original language can give you insights you otherwise may have missed by consuming it in English.

Moreover, modern writers (and by modern I mean beginning in the 17th century) often pepper their work with Latin words and phrases without offering a translation because they (reasonably) expect the reader to be familiar with it. This is true of great books from even just a few decades ago (seems much less common these days – which isn’t a hopeful commentary on the direction of the public’s literacy I would think). Not having a rudimentary knowledge of Latin will cause you to miss out on fully understanding what the writer meant to convey.

Below we’ve put together a list of Latin words and phrases to help pique your interest in learning this classical language. This list isn’t exhaustive by any stretch of the imagination. We’ve included some of the most common Latin words and phrases that you still see today, which are helpful to know in boosting your all-around cultural literacy. We’ve also included some particularly virile sayings, aphorisms, and mottos that can inspire greatness or remind us of important truths. Perhaps you’ll find a Latin phrase that you can adopt as your personal motto. Semper Virilis!
