What Does PS Mean in a Letter? Discover Its Surprising Origin

When reading or writing letters, emails, or even handwritten notes, you might encounter the abbreviation “PS” appended at the end. It’s a small addition but carries a distinct purpose that often piques curiosity. Understanding what “PS” means and where it originated can enrich your communication skills and add depth to your writing.

At its core, “PS” stands for “postscript.” This term refers to an additional thought or message added after the main body of a letter has been completed and signed. It’s a way for the writer to include information they forgot or decided to add after finishing the letter.

The Meaning of PS in Letters

In the context of written communication, “PS” is used to indicate an afterthought. The writer places it after the signature line to communicate something that wasn’t included in the main text. This practice ensures the message still reaches the reader without the need to rewrite or resend the entire letter.

For example, you might write a letter to a friend about your recent trip, sign off with your name, and then add “PS: I forgot to mention the amazing bakery we found!” This small addition provides extra value without disturbing the flow of the original message.

How PS Functions in Modern Communication

Even in digital communication such as emails and text messages, “PS” remains popular. It serves the same purpose—adding a brief note after the main message. In fact, the “PS” section in emails can be strategically used to highlight key points, calls to action, or reminders.

Marketers often use “PS” in their emails to capture attention and improve engagement. This is because readers naturally gravitate toward postscripts, making them a powerful tool in persuasive writing.

The Surprising Origin of PS

The use of “PS” dates back to ancient times, long before the invention of the printing press or email. Its roots trace to classical Latin, the language of scholars and official documents in ancient Rome.

The abbreviation “PS” comes from the Latin phrase “post scriptum,” which literally translates to “written after.” This phrase was used to indicate that a note had been added after the main body of the text was completed. It reflects the manual and meticulous nature of writing and communication in earlier eras.

Historical Context of Postscript

In the days of handwritten letters, once a letter was signed, it was considered complete. However, writers sometimes remembered additional information after signing. Rather than rewriting the entire letter, they would add a postscript at the bottom to include this new information.

This practice was practical and time-saving. It also allowed for a more spontaneous and conversational tone, showing the writer’s immediate thoughts and personality.

Examples of PS Usage in Different Contexts

Understanding how to use “PS” effectively can enhance your writing in multiple contexts. Below are examples illustrating its use in personal, professional, and marketing communications.

Personal Letters

Dear Grandma,

I had a wonderful time visiting you last weekend. Thank you for the delicious meals and warm hospitality.

Love,

Emma

PS: I found the recipe for your famous apple pie—can’t wait to try it!

In this example, the postscript adds a friendly, informal touch that might feel more spontaneous than the main body of the letter.

Professional Emails

Dear Mr. Johnson,

Thank you for considering our proposal. We look forward to the possibility of working together.

Best regards,

Sarah Lee

PS: Please don’t hesitate to reach out if you have any questions about the attached documents.

Here, the “PS” serves as a polite reminder and encourages further communication without interrupting the main message.

Marketers use the postscript to create urgency and boost conversions, leveraging the reader’s natural curiosity about postscripts.

Why Does PS Remain Relevant Today?

With modern technology, one might assume that postscripts would become obsolete. After all, digital communication allows for easy editing and instant updates. But “PS” endures for several key reasons.

First, it captures attention by breaking the usual flow of the message. Readers tend to skim or skip parts of emails and letters, but a “PS” stands out as a distinct element. It can highlight critical information or a call to action effectively.

Second, the postscript adds a conversational and personal touch to communication. It simulates the natural flow of thoughts—sometimes random, sometimes important—that occur after the main message is complete.

Psychological Impact of PS

Studies in communication psychology suggest that postscripts are among the most-read parts of letters and emails. This is because they appear as an unexpected addition, creating curiosity and engagement.

Using “PS” strategically can improve the reader’s response rate and retention of the message. This insight is why many professional writers and marketers continue to use postscripts effectively.

How to Use PS Correctly

Understanding the correct placement and formatting of “PS” is crucial for maintaining professionalism and clarity in your writing.

Always place “PS” after the signature line. It should be clearly marked with the letters “PS” followed by a colon (PS:), then the additional text.

Keep the postscript brief—one or two sentences usually suffice. Overloading the “PS” section can confuse readers and dilute its impact.

Multiple Postscripts

If you need to add more than one postscript, use “PPS” for the second, “PPPS” for the third, and so on. However, using multiple postscripts is less common and may appear cluttered.

Example:

PS: Don’t forget to bring your ID to the event.

PPS: The venue has free parking available.

Such usage was more common in handwritten letters but can still be used for effect in modern communication.

Common Misconceptions About PS

Many people believe “PS” is outdated or irrelevant in digital communication. While the context has evolved, the function remains valuable.

Another misconception is that “PS” is informal and should be avoided in business writing. In reality, a well-placed postscript can add professionalism and clarity when used appropriately.

Finally, some confuse “PS” with other abbreviations like “RSVP” or “FYI.” Each serves a different purpose and context, so understanding the distinctions is key.

Beyond Letters: PS in Popular Culture and Media

Postscripts have transcended the written letter and appear in books, movies, and social media. Authors sometimes include postscripts at the end of chapters or books to provide additional insights or tease sequels.

On social media platforms, users frequently add “PS” to captions or comments to share extra thoughts or jokes, maintaining the conversational tone of the original practice.

Creative Uses of PS

Writers and bloggers use “PS” to engage readers by adding unexpected information or humorous remarks. This can build rapport and make content more memorable.

For instance, a blog post about travel might end with:

PS: If you visit Paris, try the croissants at Café de Flore—they’re worth the early morning line!

This encourages readers to act on the advice and adds a personal recommendation, enhancing the authenticity of the content.

Summary and Final Thoughts

“PS” is a small but powerful element in writing that stands for “postscript,” derived from the Latin “post scriptum,” meaning “written after.” Its origin reflects the historical need to add additional thoughts after the main message was complete.

Despite technological advances, “PS” remains relevant and effective in both personal and professional communication. It serves as a tool to capture attention, add personality, and emphasize important points.

By understanding the history, correct usage, and psychological impact of “PS,” writers can enhance their communication and connect more meaningfully with their readers. Whether you’re penning a heartfelt letter, crafting a professional email, or composing marketing content, incorporating a well-placed postscript can make your message stand out.
