Spain
As a percentage of the general population of all Spain, Spanish is natively spoken by 74%, Catalan by 17%, Galician by 7% and Basque by 2% of all Spaniards. Occitan is spoken by less than 5,000 people, only in the small region of "Val d'Aran".
Other Romance minority languages, though not official, have special recognition, such as the Astur-Leonese language ("asturianu", "bable" or "llionés") and Aragonese ("aragonés") in Aragon.
Salvadoran Spanish
Salvadoran Spanish is geographically defined as the form of Spanish spoken in the country of El Salvador. The Spanish dialect in El Salvador shares many similarities to that of its neighbors in the region, but it has its stark differences in pronunciation and usage. Salvadoran Spanish is the only Spanish dialect in North America to be usually called "castellano", instead of "español". El Salvador, like most of Central America, uses voseo Spanish as its written and spoken form, similar to that of Argentina. Vos is used, but many Salvadorans understand tuteo. Vos can be heard in television programs and can be seen in written form in publications. "Usted" is used as a show of respect, when someone is speaking to an elderly person.
