Infante
An "Infante" is a title used in Spain and Portugal to refer to a prince or princess who is not the heir to the throne. This title is typically given to the younger children of the reigning monarch. The term is derived from the Spanish word "infante," meaning "infant" or "child," reflecting their status as non-heirs.
In the context of royal families, Infantes often have specific roles and responsibilities, but they do not have the same privileges as the heir apparent. The title can also be found in historical contexts, such as with Infante Don Juan Manuel, a notable Spanish writer and nobleman from the 14th century.
