Postscript - wikipedia Postscript This article is about the afterthought. For the programming language, see PostScript. For other uses, see Postscript ( disambiguation ). `` P.S. '' redirects here. For other uses, see PS ( disambiguation ). A postscript ( P.S. ) is an afterthought, thought of occurring after the letter has been written and signed. The term comes from the Latin post scriptum, an expression meaning `` written after '' ( which may be interpreted in the sense of `` that which comes after the writing '' ). A postscript may be a sentence, a 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. The word `` postscript '' has, poetically, been used to refer to any sort of addendum to some main work, even if it is not attached to a main work, as in Søren Kierkegaard 's book titled Concluding Unscientific Postscript. Sometimes, when additional points are made after the first postscript, abbreviations such as PSS ( post-super - scriptum ), PPS ( postquam - post-scriptum or post-post - scriptum ) and PPPS ( post-post - post-scriptum ), and so on, ad infinitum are used, though only PPS has somewhat common usage.
