The term pharaoh ultimately was derived from a compound word represented as pr-ꜥ3, written with the two biliteral hieroglyphs pr "house" and ꜥꜣ "column". It was used only in larger phrases such as smr pr-aa '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.
