Etymology

Following the amalgamation of the Kingdom of Hejaz and Nejd, Abdulaziz bin Saud issued a royal decree on 23 September 1932 naming the new state al-Mamlaka al-ʿArabiyya as-Suʿūdiyya (Arabic المملكة العربية السعودية), which is normally translated as "the Kingdom of Saudi Arabia" in English, but literally means "the Saudi Arab Kingdom ", or "the Saudi Kingdom of Arabia " (compare the Hashemite Kingdom of Jordan).

The word "Saudi" is derived from the element as-Suʿūdīyya in the Arabic name of the country, which is a type of adjective known as a nisba, formed from the dynastic name of the Saudi royal family, the Al Saud (Arabic: آل سعود). Its inclusion expresses the view that the country is the personal possession of the royal family. Al Saud is an Arabic name formed by adding the word Al, meaning "family of" or "House of", to the personal name of an ancestor. In the case of Al Saud, this is Saud ibn Muhammad ibn Muqrin, the father of the dynasty's 18th-century founder, Muhammad bin Saud.
