INFANTE (Spanish and Portuguese form of Lat. infans, young child), a title of the sons of the sovereign of Spain and Portugal, the corresponding infanta being given to the daughters. The title is not borne by the eldest son of the king of Spain, who is prince of Asturias, 77 principe de Aslurias. Until the severance of Brazil from the Portuguese monarchy, the eldest son was prince of Brazil. While a son or daughter of the sovereign of Spain is by right infante or infanta of Spain, the title, alone, is granted to other members of the blood royal by the sovereign.
