PS means “PhotoShop” or “Play Station” or “Post Script”. So now you know – PS means “PhotoShop” or “Play Station” or “Post Script” – don’t thank us. A postscript (from post scriptum, a Latin expression meaning “after writing” and abbreviated PS) is a sentence, paragraph, or occasionally many paragraphs added, often hastily and incidentally, after the signature of a letter or (sometimes) the main body of an essay or book. In a book or essay, a more carefully-composed addition (e.g., for a second edition) is called an afterword. An afterword, not usually called a postscript, is written in response to critical remarks on the first edition. The word has, poetically, been used to refer to any sort of addendum to some main work, even if not attached to a main work, as in Søren Kierkegaard’s book titled Concluding Unscientific Postscript.
