What Does P.S. Mean?

The abbreviation P.S. is short for “postscript” and is used to include additional information at the end of a letter, email or other document.

“Postscript” is derived from the Latin word postscriptum, which translates to “written after.” Post means after and scriptum means written. The term postscript first entered the English lexicon in the early 1500s and has remained popular over the centuries.

Why Use P.S.?

The concept of including a postscript at the end of a document dates back to an era when letter writing was the dominant method of communication. Because a person could not go back and edit the handwritten letter, they would simply include a postscript with the additional information they forgot to include in the body of the letter. This tradition has endured in the email age and is often used to add or highlight important information at the end of digital communication.

P.S. is a commonly used abbreviation that indicates an afterthought or additional information that was not included in the main body of the letter or email correspondence. A postscript can also draw the reader’s attention and emphasize important content that would otherwise get lost in the text. Because of this, it is often used in email marketing to indicate a clear call to action and highlight the message of the document.

How to Write P.S.

While P.S. is typically written with both the “P” and “S” capitalized with periods between each letter, it can be written a couple of different ways.

  • The standard form in American English is P.S. with periods after each letter.
  • The Chicago Manual of Style favors PS without periods.
  • In British English, the standard form is PS without periods.

How to Punctuate P.S.

Sometimes the postscript is followed by further punctuation. This can vary widely. Most styles use a colon (:) after P.S., while others use a dash (-). Still, others may not use any punctuation at all other than the periods between letters. However you write your postscript, consistency is key!

Where to Place P.S.

The postscript should always follow the signature at the end of a letter. It should never be placed before the closing. The purpose of P.S. is to include important information that was not in the body of the text. In the example below, the postscript emphasizes when the forms are due and the urgency of the task.
