Pharaoh (/ˈfeɪ.roʊ/, /fɛr.oʊ/ or /fær.oʊ/) is the common title of the monarchs of ancient Egypt from the First Dynasty (c. 3150 BCE) until the Macedonian conquest in 305 BCE, although the actual term "Pharaoh" was not used contemporaneously for a ruler until circa 1200 BCE.
The word pharaoh ultimately derive from the Egyptian compound pr-ˤ3 "great house," written with the two biliteral hieroglyphs pr "house" and ˤ3 "column", here meaning "great" or "high". It was used only in larger phrases such as smr pr-ˤ3 'Courtier of the High House', with specific reference to the buildings of the court or palace. From the twelfth dynasty onward, the word appears in a wish formula "Great House, may it live, prosper, and be in health", but again only with reference to the royal palace and not the person.
