P.S. (or PS) means “postscript,” which comes from the Latin post scriptum , meaning “written after.” It’s a short extra message you add at the end of a letter, email, or post after you’ve already finished the main text and signed off.

Quick Scoop: What does P.S. mean?

  • P.S. stands for “postscript,” literally “written after.”
  • It’s used for an extra thought, reminder, or emphasis that comes after the main message.
  • You’ll see it in letters, emails, texts, and social media captions.

Example:
“Thanks again for reading this.
P.S. Don’t forget to reply by Friday!”

How P.S. is used today

  • In letters and emails: A short add-on after your name, often to highlight something important or personal.
  • In texts and DMs: A playful way to tack on a last comment or joke.
  • On social media: Used in captions to draw attention, invite comments, or add a punchline at the end of a post.

Common patterns:

  1. Afterthought: Something you forgot to say in the main message.
  2. Emphasis: Repeating or highlighting the most important point.
  3. Reminder or CTA: “P.S. The link is in my bio.”

Little style details (if you’re curious)

  • You can write it as “P.S.” or “PS” – both are accepted; “P.S.” is more traditional, “PS” is common in modern English.
  • Usually written in caps with a colon: “P.S: …” or “P.S.: …”, depending on style.
  • If you add another one, it becomes “P.P.S.” (post-postscript) for a second extra note.

Example flow in an email:

  1. Write main message.
  2. Add closing (e.g., “Best,”).
  3. Sign your name.
  4. On a new line, add “P.S. Your quick reminder goes here.”

Why people still use P.S. (even online)

  • It grabs attention: readers often skim, but their eyes catch the line at the end marked P.S.
  • It feels personal and conversational, like a whispered “oh, one more thing…”
  • Marketers use it in emails to restate the main offer or key benefit, because that line is highly noticeable.

TL;DR: P.S. means “postscript” – a short extra message added at the end of your letter, email, or post, for afterthoughts, reminders, or emphasis.
