PS stands for "postscript," a note added at the end of a letter after the writer's signature. This Latin-derived term literally means "written after," serving as an appendix for additional thoughts.
A postscript appears below the writer's name and signature, often marked with "P.S." in bold or underlined. The content typically addresses minor points overlooked in the main letter. For example:
Dear Alex,
I hope you're well...
Best,
Jamie
P.S. Don't forget to water my plants while I'm away!
Postscripts create visual separation from the primary message, ensuring important details aren't buried in the body text.
| Type | Purpose | Example |
|---|---|---|
| Reminder | Add forgotten tasks | P.S. Please return the library books by Friday. |
| Personal | Share intimate thoughts | P.S. I miss you already. |
| Informational | Provide additional facts | P.S. The meeting has been moved to Conference Room B. |
Professional correspondence often omits postscripts entirely. In formal letters, include all necessary information in the body text rather than relying on PS notes. Business letters may use "Enclosure" or "Attachment" instead when referencing additional documents.
The postscript dates to medieval times when writers added notes after signing letters. The practice became widespread during the 17th century as literacy rates increased. Today, email signatures sometimes include "P.S." sections, maintaining this centuries-old tradition in digital communication.
According to the Britannica Encyclopedia, the term "postscript" first appeared in English around 1659. While its usage has evolved, the core function remains unchanged: providing supplementary information after the main content.
Use postscripts sparingly-ideal for minor details that don't warrant inclusion in the letter's body. They work well for personal correspondence but appear less frequently in professional settings. When writing a letter, consider whether the information belongs in the main text or as a postscript.
For example, a thank-you letter might include:
P.S. Your kindness meant more than words can express.
This addition enhances the emotional impact without disrupting the letter's flow.
