When communicating in English, the placement of punctuation around the abbreviation for "postscript" often causes confusion. Whether you are writing a formal letter, a marketing email, or a casual note, understanding how to punctuate ps correctly maintains clarity and professionalism. The core principle involves positioning the period that follows the abbreviation and deciding whether to include a comma before the text it introduces.
Standard Format for PS
The most widely accepted format is "P.S." with periods after each letter and a comma following the abbreviation. This comma acts as a visual and grammatical separator, indicating that the following words are an addition to the main body of the letter. For example, you would write: "P.S., I forgot to mention the meeting time." This structure ensures the reader immediately recognizes the abbreviation as a distinct, inserted thought.
Comma Usage and Omissions
While the comma after "P.S." is standard in business correspondence and academic writing, some style guides for creative writing or informal communication allow the comma to be omitted. In these cases, the sentence might read: "I will see you tomorrow P.S. bring the documents." However, removing the comma can sometimes create ambiguity about where the main text ends and the postscript begins. Using the comma is generally the safer choice for maintaining a professional tone and avoiding misinterpretation of your intended emphasis.
Handling Multiple Additions
If you need to include more than one postscript, the traditional method involves labeling them as "P.S." for the first addition and "P.P.S." for the second, with each receiving its own period and comma. An increasingly common modern approach is to simply number them, such as "PS1" and "PS2," which can reduce visual clutter. When using the numerical format, maintain consistency by applying the same punctuation style—either with periods like "PS. 1" or without, depending on your style guide preference.
Digital Communication Considerations
In emails and text messages, the rigid rules of punctuation often relax to accommodate speed and readability. It is still advisable to capitalize "PS" and include the period, but the comma may be dropped if the message is brief. The key is to remain consistent throughout your correspondence. If you use a comma in one email, using it in all subsequent emails ensures your writing appears deliberate and polished rather than accidental.
Avoiding Common Typos
A frequent error is writing "P.S" with only one period, which looks incomplete in standard English typography. Another is confusing "PS" with "PS," where the latter might be misinterpreted as an abbreviation for physicals or pounds square. Always double-check that you have typed two distinct periods and that there is no unwanted space between the letters. Correct punctuation prevents these minor mistakes from undermining the professionalism of your written communication.
