A Brief History of Punctuation Marks

If you write, you use punctuation every day without even thinking about it. Periods end sentences, commas organize ideas, question marks signal curiosity, and so on... but these symbols weren’t always part of the writing lexicon. Many evolved from ancient scholarship, medieval handwriting, annoyed monks, and even business shorthand.
Here’s a quick tour through the surprisingly fascinating history of the punctuation you use in your writing to this day!
The Ampersand (&)
The ampersand began as a stylized version of the Latin word “et,” meaning and. Roman scribes wrote the letters together in a flowing ligature that gradually transformed into the symbol we recognize today.
The name ampersand comes from how the symbol was once taught in the alphabet. It appeared at the end and was read aloud as “and per se and.” Over time, that phrase was shortened into the word ampersand.

The Comma (,)
The idea behind the comma dates back to ancient Greek scholars who created marks to show pauses when reading aloud.
Centuries later, medieval scribes used a diagonal slash called the virgula suspensiva ( / ) to mark brief pauses in text.
By the 17th century, that slash slowly curved downward into the comma we use today.
The Period (.)
The period (also called a full stop in more posh circles) comes from an ancient punctuation system created by the Greek scholar Aristophanes of Byzantium.
His system used dots placed at different heights to indicate pauses of varying length. Over time those marks were simplified, leaving us with the single dot that signals the end of a sentence.
The Exclamation Mark (!)
One theory suggests the exclamation mark originated from the Latin expression “io,” which conveyed excitement or joy.
Medieval writers sometimes placed the letters at the end of a sentence for emphasis. Eventually the I was compounded to be written above the O, creating the stacked form that evolved into the modern exclamation mark!
The Question Mark (?)
The question mark is one of the oldest punctuation marks, though its exact origin is debated.
Some historians believe it may come from the Latin word quaestio, meaning “question,” written as an abbreviation and gradually stylized into the curved mark we know today. Crazy, right?
The Apostrophe (’)
The apostrophe appeared in 15th-century Italian printing and was originally used to show omitted letters. It's common to find in Shakespearean-era texts.
For example:
loved → lov’d
English later adopted the mark to show possession. Words like kinges eventually became king’s, and the apostrophe spread to other nouns.
The Hyphen (-)
The hyphen dates back to ancient Greek grammar, as most things do. Early writers used it to signal that two words should be read together as one. The word originated from the Greek enotikon (or hupo/hen, meaning "under one"), a tie mark placed below words to show they should be read together, created by scholars like Dionysius Thrax around 100 BC.
In medieval manuscripts it served another purpose: fixing words that were incorrectly spaced or split between lines. When printing presses appeared in the 15th century, the mark moved from below the text to the middle of the line, becoming the hyphen we use today.
The Semicolon (;)
The semicolon was introduced in the 16th century as a punctuation mark between a comma and a period.
Originally it simply represented a pause of medium length. By the 18th century, it had developed its modern role: linking closely related sentences that could stand on their own.
The Colon (:)
The colon likely evolved from the same ancient Greek pause-marking system that produced the period and comma.
Early writers used it to indicate a pause longer than a comma but shorter than a full stop. Later it gained new functions, such as introducing lists or explanations.
The Asterisk (*)
The asterisk may be the oldest punctuation mark still in use today. It's stood the test of time and is virtually unchanged.*
Ancient scholars used it as early as the 2nd century BC to mark corrections or notes in important texts. Medieval scribes continued using it in manuscripts, and it eventually became a common symbol for footnotes and annotations.

The Slash (/)
The slash actually began as a punctuation mark similar to a comma.
In medieval writing, the virgule ( / ) was used to mark pauses in text before the comma replaced it.
Today the slash appears everywhere—from dates to fractions to computer file paths.
The Hashtag/Pound (#/lb)
Long before social media and the #gram, the hashtag symbol represented “pound weight.”
It evolved from the abbreviation lb, derived from the Latin phrase libra pondo. Over time the symbol became associated with numbers in accounting and eventually developed into the modern hashtag. #punctuationhistoryftw
The Tilde (~)
The tilde originally served as a medieval shorthand mark. Scribes used it to show that letters had been omitted from frequently written words. If you squint, it's the precursor to written text slang.
Today the symbol appears in several languages and technical contexts, though its original abbreviative function has mostly disappeared.
Final Thoughts
Punctuation may seem simple, but every mark on the keyboard carries centuries of history. Many began as tools to help readers pause, breathe, or understand a sentence more clearly.
From ancient Greek scholars to medieval scribes to modern keyboards, punctuation has continually evolved alongside language but its purpose remains the same: helping ideas make sense on the page. Keep those intentions and meanings in mind while crafting your own writing work!
