Lusitanic is a term used to refer to people who share the linguistic and cultural traditions of the Portuguese-speaking nations, territories, and populations, including Portugal, Brazil, Madeira, Macau, Timor-Leste, Azores, Angola, Mozambique, Cape Verde, São Tomé and Príncipe, Guinea Bissau and others, as well as the Portuguese diaspora generally. The term is derived from Lusitanian ('person of Lusitania', , fem. ; from , from , the name of a Roman province in the Iberian Peninsula, which encompassed most of modern Portugal). Luso- is a Late Latin prefix used to denote Portugal/Portuguese, in conjunction with another toponym or demonym. A Lusophone () is someone who speaks the Portuguese language, either natively or as an additional language. As an adjective it means 'Portuguese-speaking'. The Lusosphere or Lusophony (), is the totality of Portuguese speakers around the world, and the influence of the language and culture. Origin The term derives from the name of one Ibero-Celtic tribe, the Lusitani, that lived in the north-western part of the Iberian Peninsula prior to the Roman conquest; the lands they inhabited were known as Lusitania. The Lusitani were mentioned for the first time, by Livy in the 1st century BCE, as Carthaginian mercenaries who were incorporated in the army of Hannibal when he fought the Romans. Pliny the Elder states in Naturalis Historia (77–79 CE) that the Lusitanians were Celtiberians in particular, and ancestral to the Celtici of Baetica (now western Andalusia, Spain). The ultimate etymology of , like the origin of the Lusitani who gave the province their name, is unclear. By popular etymology in previous centuries, the name was connected to a supposed Roman demigod Lusus (literally 'Game', a personification of gaming found only in late Roman poetry) combined with an unattested "Celtic" word for 'tribe' or 'region': *Lus- + *-tanus, 'tribe of Lusus'. Others connected Lus- with the Celtic god Lugus. After the conquest of the peninsula (25–20 BCE), Augustus divided it into the southwestern Hispania Baetica and the western Hispania Lusitania, the latter including the territories of the Celtic tribes known as the Astures (in Asturia) and the Gallaeci (in Gallaecia). In 27 BCE, the Emperor Augustus made a smaller division of the province: Asturia and Gallaecia were ceded to the jurisdiction of the new province Tarraconensis, the former remained as Provincia Lusitania et Vettones. The Roman province of Lusitania comprised what is now central and south Portugal and parts of north-central
