What is "royal we"

n. The first-person plural pronoun ''we'' as traditionally used by a sovereign in formal speech to refer to himself (herself) in their role as the monarch.

The royal "we", or majestic plural (pluralis majestatis in Latin, literally, "the plural of majesty"), is the use of a plural pronoun to refer to a single person holding a high office, such as a sovereign (e.g., a monarch or sultan) or religious leader (e.g., the Pope or a bishop). The more general word for the use of we to refer to oneself is nosism.

Speakers employing the royal we refer to themselves using a grammatical number other than the singular (i.e., in plural or dual form). For example, the Basic Law of the Sultanate of Oman opens with "On the Issue of the Basic Law of the State We, Qaboos bin Said, Sultan of Oman...".
