Pharaoh is a title used in many modern discussions of the ancient Egyptian rulers of all periods. The title originates in the term ‘’pr-aa’’ which means ‘’great house’’ and describes the royal palace. The title of Pharaoh started being used for the king during the New Kingdom, specifically during the middle of the eighteenth dynasty. For simplification, however, there is a general acceptance amongst modern writers to use the term to relate to all periods. ~ from Wikipedia.
