What does "PS" mean?

“PS” is an abbreviation that stands for “postscript.” It is derived from the Latin “post scriptum,” which means “written after.” Historically, “PS” was used in written correspondence to add additional information that was forgotten or deemed important after the main body of the message was written. In modern usage, “PS” can be used in written or digital correspondence to indicate a quick afterthought or to add additional information at the end of a message. It is commonly used in email communication to add a final message or to draw attention to important information.
