The Royal Spanish Academy (Spanish: Real Academia Española, RAE), the official royal institution responsible for regulating the Spanish language defines the terms "Hispano" and "Hispánico" (which in Spain have slightly different meanings) as: Note that both terms include Portugal as part of "Hispania" as Hispania is the old Roman name given to the entire Iberian peninsula and their peoples, including the Lusitanians.
The common modern term to identify Portuguese and Spanish cultures under a single nomenclature is "Iberian", and the one to refer to cultures derived from both countries in the Americas is "Iberian-American".
Along with English and Tagalog, Spanish used to be one of the official languages in the Philippines before being removed in 1973 by the Cory Aquino government.The Latin gentile adjectives that belong to Hispania are Hispanus, Hispanicus, and Hispanienses.These designations can be mutually recognized by people in Portugal and Brazil, unlike "Hispanic", which is totally void of any self-identification in those countries, and quite on the opposite, serves the purpose of marking a clear distinction in relation to neighboring countries´ culture.In Spanish, the term "hispano" as in "hispanoamericano", refers to the people of Spanish origin who live in the Americas; it also refers to a relationship to Hispania or to the Spanish language.) broadly refers to the people, nations, and cultures that have a historical link to Spain.
It commonly applies to countries once owned by the Spanish Empire in the Americas (see Spanish colonization of the Americas) and Asia, particularly the countries of Hispanic America and the Philippines.
In the Council of Constance, the four kingdoms shared one vote.
The word Lusitanian, relates to Lusitania or Portugal, also in reference to the Lusitanians, possibly one of the first Indo-European tribes to settle in Europe.
Hispanicus implies 'of' or 'belonging to' Hispania or the Hispanus or of their fashion as in "glaudius Hispanicus".
The gentile adjectives were not ethnolinguistic but derived primarily on a geographic basis, from the toponym Hispania as the people of Hispania spoke different languages, although Livy said they could all understand each other, not making clear if they spoke dialects of the same language or were polyglots.
From this tribe's name had derived the name of the Roman province of Lusitania, and Lusitania remains the name of Portugal in Latin.
