cozido) and dry-cured (presunto cru)), or castelhano ('Castilian'), from Spanish melena ('mane'), fiambre and castellano. Classification and related languages Portuguese belongs to the West Iberian branch of the Romance languages, and it has special ties with the following members of this group: Galician, Fala and portunhol do pampa (the way riverense and its sibling dialects are referred to in Portuguese), its closest relatives. Mirandese, Leonese, Asturian, Extremaduran and Cantabrian (Astur-Leonese languages). Mirandese is the only recognised regional language spoken in Portugal (beside Portuguese, the only official language in Portugal). Spanish and calão (the way caló, language of the Iberian Romani, is referred to in Portuguese). Portuguese and other Romance languages (namely French and Italian) share considerable similarities in both vocabulary and grammar. Portuguese speakers will usually need some formal study before attaining strong comprehension in those Romance languages, and vice versa. However, Portuguese and Galician are fully mutually intelligible, and Spanish is considerably intelligible for lusophones, owing to their genealogical proximity and shared genealogical history as West Iberian (Ibero-Romance languages), historical contact between speakers and mutual influence, shared areal features as well as modern lexical, structural, and grammatical similarity (89%) between them. Portuñol/Portunhol, a form of code-switching, has a more lively use and is more readily mentioned in popular culture in South America. Said code-switching is not to be confused with the Portuñol spoken on the borders of Brazil with Uruguay () and Paraguay (), and of Portugal with Spain (), that are Portuguese dialects spoken natively by thousands of people, which have been heavily influenced by Spanish. Portuguese and Spanish are the only Ibero-Romance languages, and perhaps the only Romance languages with such thriving inter-language forms, in which visible and lively bilingual contact dialects and code-switching have formed, in which functional bilingual communication is achieved through attempting an approximation to the target foreign language (known as 'Portuñol') without a learned acquisition process, but nevertheless facilitates communication. There is an emerging literature focused on such phenomena (including informal attempts of standardization of the linguistic continua and their usage). Galician-Portuguese in Spain The closest relative of Portuguese is Galician, which is spoken in the autonomous community (region) and historical nationality of Galicia (northwestern Spain). The two were at one time a single language, known today as Galician-Portuguese, but they have diverged especially in pronunciation and vocabulary due to the political separation of Portugal from Galicia. There is, however, still a linguistic
