O’ Latin, wherefore art thou ‘dead’?

After seven years of studying Latin, I’ve heard every version of the same question: “Why are you studying a dead language?” As a four-time National Latin Exam Gold Medalist (summa cum laude) and co-president of my school’s Latin Club, I’ve gotten used to defending my choice. I usually say something about intellectual rigor or cultural richness. But Latin didn’t become fully alive to me until I found it somewhere unexpected.

The first time I opened a research paper on immune-oncology, I braced myself for confusion. The page was riddled with terms like “ligand” and “extravasation,” and for a moment, it felt like I had been dropped into a foreign country. Every sentence I read was a street I didn’t recognize. But then, squinting through the haze, I saw someone familiar. I made out her sinuous silhouette and her soft voice. It was Latin, my old friend. She was here to be my tour guide, just donning a lab coat instead of a toga.

She trickled through dense paragraphs, leaving a clear path in her wake, the way streams of water dissolve structured rock. She leaked through the page, illuminating small patches of light in otherwise murky territory. She was inarguably alive.

With her guidance, I took one step at a time, just as she had trained me to translate Vergil’s The Aeneid and Caesar’s Gallic Wars. I started breaking words apart. “Ligand,” the surface proteins that connect cells and send signals, became ligare, to bind. “Malignant” split into mal, bad, and gignere, to give birth. So, really, malignant cells are not just dangerous; they are literally born wrong. The word “immunity,” itself, comes from the Latin words im, not, and munus, duty or service. So, a functioning immune system is exempt from the duty of fighting disease. When I learned that cancer cells can survive and spread by mimicking that exemption, I imagined them sneering through deceitful grins at T cells: “You have no obligation here, move along.” Now, each of these words had a story beyond just a definition. Once I stopped trying to memorize these terms, reading scientific literature became more like solving a puzzle, where the clues were hidden in plain sight.

Near the end of a paper, deep in a tangle of receptor pathways and signaling cascades, I glanced up and realized I was no longer lost. I had no one to thank but my faithful guide, Latin. In a sense, she had never died. Her ghost is alive in many modern languages, including the language of science, but only to those who choose to see her.
