infanta
A daughter of the sovereign of Spain or Portugal.
Noun
pl: infantas
This term is a specific title of nobility used exclusively within the Iberian monarchies. It carries a connotation of high royal status but distinguishes the holder from the direct heir to the throne, who would typically hold a different title such as Princess of Asturias in Spain.
Because it is a loanword from Spanish and Portuguese, it retains a formal, historical aura. It is used primarily in diplomatic, genealogical, or historical contexts to denote a specific rank within the royal hierarchy rather than as a general term for any royal daughter.
