<P> The form of Portuguese spoken in Brazil is a little different from that spoken in Europe, with differences in vocabulary and grammar that can be compared to the differences between American and British English, but with the phonology and prosody more distinct to each other (on a slightly larger scale than that of the Metropolitan and Québécois varieties of French); nevertheless, European and Brazilian Portuguese are completely mutually intelligible . The vast majority of Brazilian characteristics are also found in some rural, remote Portuguese registers (or the African and Asian ones, indicating an Old Portuguese feature lost in Europe), while nearly all distinctive European characteristics can be found in any major dialect of Brazil (such as fluminense, specially its carioca sociolect, and florianopolitano), due to a stronger or more recent Portuguese and other European immigration . </P> <P> Migration from Brazil also led to a great number of Portuguese speakers in the Southern Cone (especially Uruguay with portunhol da pampa), Paraguay (see brasiguayos), other regions of South America (especially Bolivia) except Venezuela, Japan (see Brazilians in Japan 400,000 and dekasegi, official numbers do not include second generation Portuguese speakers and naturalized citizens), South Korea, the Philippines (see Brazilians in the Philippines), and Israel (see Aliyah from Latin America in the 2000s). </P> <P> Although Brazil is the only Portuguese - speaking nation in South America, it has the largest population, area and economy on the continent . Thus, the South American trade bloc Mercosul uses Portuguese alongside Spanish as its working languages . A Spanish influenced Portuguese dialect is spoken in the northern Uruguayan border area with Brazil . Given the proximity and trading relations between Portuguese speaking Brazil, and its respective Spanish speaking nations, Portuguese is offered as a foreign (or obligatory) second language course at most schools in Uruguay, Argentina, Paraguay, Venezuela and Bolivia . </P> <P> In Venezuela and Guyana, there are communities of Portuguese immigrants (mostly Madeirans) and their descendants who speak Portuguese as their native language . </P>
