Postscript Law and Legal Definition
Postscript postscript is a note added to a letter after the signature. It can also be the written matter added at the end of a publication. The word PS or Postscript comes from the Latin word "post scriptum" which means "after writing."
A postscript can be in the form of a line or a paragraph added after the signature of a letter. Post script is usually written when a writer forgets to write something on the main body of the letter and wants to add on to what he had written on the letter. Though people usually use "PS" to write something that had slipped out of their memory in a letter, it may also be used to emphasise something or to take the reader by surprise.
