Frequently Asked Questions
What does PS mean at the end of a letter?
It stands for the Latin post scriptum, "written after", and marks something added once the letter was finished and signed. It was originally a practical fix for handwritten letters that could not be redrafted, and it survives in email as a way of flagging an extra or informal point.
What is the difference between PS and PPS?
PS marks the first addition after the signature; PPS, from post post scriptum, marks a second one after that. A third is PPPS, though at that point most writers just rewrite the message.
Is it PS or P.S.?
Both are correct. P.S. with full stops is traditional and still standard in American English; PS without them is now the more common style, particularly in British writing and email.
