Lusitanic

Lusitanic (Portuguese Lusitânico), from Latin Lusitanicus, adjective from Lusitania, the name of a Roman province in the Iberian Peninsula and one of the two official names for Portugal (in the Latin language) is a term used to categorize persons who share the linguistic and cultural traditions of the Portuguese.

Luso is a Late Latin prefix used to denote Portuguese- in conjunction with another toponym or demonym. The word is derived from Lusitania, the Latin name for what would be modern Portugal. Lusitania was an ancient Roman province including approximately all of modern Portugal south of the Douro river and part of modern Spain (the present autonomous community of Extremadura and a small part of the province of Salamanca). It was named after the Lusitanians or Lusitanian people (an Indo-European people). Its capital was Emerita Augusta (currently Mérida, Spain), and it was initially part of the Roman Republic province of Hispania Ulterior, before becoming a province of its own in the Roman Empire. The etymology of Lusitania, like the origin of the Lusitani who gave the province their name, is unclear. The name may be of Celtic origin: Lus and Tanus, "tribe of Lusus", connecting the name with the personal Celtic name Luso and with the god Lugh.

Lusophone (not to confuse with Lusitanic) is someone who speaks the Portuguese language, either as a native, as an additional language, or as a learner. As an adjective, it means "Portuguese-speaking". The word itself is derived from the name of the ancient Roman province of Lusitania, which covered most of the part of the Iberian peninsula that is today the Republic of Portugal and part of Spain.
