Otherwords: The History of Punctuation

Otherwords, a PBS web series on Storied takes a deep dive into one of the most quintessentially human traits: language. The show uncovers the fascinating, often surprising, and delightfully funny stories behind the words and sounds we usually take for granted. Drawing from fields as varied as biology, history, cultural studies, literature, and beyond, linguistics has something for everyone and offers a fresh perspective on what it truly means to be human.

Take punctuation, for example. Most of us rarely think about it. Periods, commas, colons… they quietly do their jobs, like the background dancers of language. But the moment someone sends a long, unpunctuated message, suddenly those little marks become your lifeline. You’re halfway through the text, thinking, “Am I still following the same thought? Did I accidentally join a cult? Where does this sentence even end?!”

Of course, it wasn’t always this neat. In the earliest days of writing, spaces didn’t exist. Words were jammed together like an ancient Twitter feed. Imagine trying to read: THECATISONTHEMAT. Is it “The cat is on the mat”? Or “The Catis on Thema T”? Who knows! Reading back then was basically playing Wheel of Fortune without the vowels—and losing half the time.

Enter the Greeks, and specifically Aristophanes of Byzantium—not the comedian, but another fellow with way too much free time and an obsession with dots. He devised a system of pause marks: one dot for a short pause, two for medium, and three for a long pause. Think of it as the world’s first traffic lights—but instead of preventing accidents, they saved sentences.

Fast forward to the Middle Ages. Christian monks painstakingly hand-copied sacred texts, realizing that a misplaced pause could dramatically alter divine meaning. Enter Bishop Isidore of Seville, who helped standardize punctuation marks into the forms we recognize today: periods, commas, and—eventually—the semicolon. Ah, the semicolon: punctuation’s middle child. Too fancy to be a comma, too timid to be a period, constantly pleading with writers: “Notice me! I can connect clauses responsibly!”

Then came silent reading, a total game-changer. Suddenly, readers didn’t need someone to chant dramatic pauses aloud. Punctuation carried the performance all on its own. Add spaces between words and the invention of the printing press, and punctuation became everywhere, quietly steering the clarity of written language.

And today? Punctuation is more than just grammar; it has personality. A period is stern and no-nonsense. A question mark is endlessly curious. The exclamation point? The drama queen of the lot. And the ellipsis… well, the ellipsis just makes you nervous, like receiving a text from your mom that says, “We need to talk…”

Now emojis are trying to muscle in on punctuation’s territory, but let’s be honest: no smiley face or crying cat can ever replace the elegance, wit, and precision of a well-placed semicolon.
