(nor is zaragossa the biggest city)
Edit: I get it now. Of all the european cities starting with z, there are two more populous than the one in spain. (but it read like the most populous city of the country started with z)
Zürich and Zagreb are the ones in question, for those curious
Until I realized I have to write the country, not the capital city...
I created an English quiz yesterday at Jetpunk, which talks about the Presidents of Brazil. This quiz was based on an original quiz in Portuguese, which talks about the same theme.
I realized, that it is already available on Jetpunk, but I would like to see it on the homepage.
Can you do that?
The predominant language in Spain is Castilian (also called Spanish), spoken by almost the entire population of the country. Other languages are of greater importance in some regions: Basque (euskera or euskara) in the Basque Country and in Navarre; Catalan in Catalonia and the Balearic Islands and in the Valencian Community (where it receives the name of Valencian); and finally Galician in Galicia (in diassystem with Portuguese on both banks of the river Minho).
Spanish or Castilian is official throughout the country; the others acquired the status of co-official languages in their respective regions from 1978, as a consequence of the Spanish transition to democracy and have great local relevance, including several publications such as daily newspapers in these languages and, especially for Catalan, the Basque and Galician, there is significant production and publication of books and media industry.
In addition, there is growing support for other regional languages, some in danger of extinction. These include the Asturian-Leonese: Asturian in Asturias and Leone in the ancient Kingdom of Leon, Aragonese in Aragon, and Aranese, a dialect of the Occitan language, spoken only in the small Aran Valley, Catalonia, but alive enough to be a co-official language and be used in your public schools.
Com a exceção do basco, que aparenta ser um idioma isolado, todos os outros são derivados do latim.
During the dictatorship of General Francisco Franco, all languages, except Castilian, were banned, with the aim of creating a united and uniform Spain, destroying any forms and factors of separatism, especially the Basque, Catalan movements, and to a lesser extent, the Galician.
San Martín de Trevejo (Sa Martim de Trevelho), Eljas (As Elhas) and Valverde del Fresno (Valverde do Fresno), in the Xálima Valley (or Xalma Valley), (Cáceres province) where the dialect is called speech.
Olivenza (province of Badajoz) - despite the disappearance since the takeover of Spain.
Cedilho (including Herrera de Alcántara or Ferreira de Alcântara).
and several villages on the border of Galicia and Castile and Leon with Portugal.
None of these situations are protected by the Spanish government, nor by regional governments, nor even by any kind of support from the government of Portugal. The use of Portuguese, the language of some of its ancestors, is discouraged by society dominated by Castilian. In spite of everything, popular organizations are beginning to emerge to keep the Portuguese language alive in Spain, as is the case of the Além Guadiana organization, composed of Oliventines.
According to the CIA World Factbook,  the distribution of the most spoken languages in Spain today is as follows:
Castilian (official) - 74%
Catalan (co-official in Catalonia, Balearic Islands and Valencian Community) - 17%
Galician (co-official in Galicia) - 7%
Basque (co-official in the Basque Country and Navarre) - 2%
But anyway, it is correct.
