You can’t live in Spain for an extended period without getting to grips with the language. Spanish is a language with more than four hundred million speakers across the world, from Latin America to Europe, and every regions has its own variation of the language. Spain itself has variations within the country, and in fact Spaniards refer to their language as Castellano rather than Spanish. This reflects the history of the language which originated in Castile, with written artifacts dating back to the ninth century. If you want to learn the Spanish equivalent of the queen’s English then you should go to Valladolid as that is where the most correct Spanish is spoken.
Studying Spanish isn’t that tough. It’s an easy language to spell, its phonetic, and the grammatical structure is not too complex. Spaniards like to use intonation rather than grammar to change the meaning of their words so I think it is fair to say that the effort you put in will be well worth it.
Castellano is not the only language spoken in Spain because there are in fact three more official languages, namely: Galician, Basque and Catalan. With such cultural diversity in Spain it is little wonder that it has four different languages. Whilst you should tailor your studies depending on where you are going in Spain it is important to realize that Spanish can be understood everywhere, even in the Catalan areas such as the Balearic islands of Mallorca, Menorca, Ibiza and Formentera.
Where Catalan is similar to French, Galician sits somewhere in the middle of the languages of Castellano and Portuguese. For survival in the rural areas of Galicia, then you need to put the effort in to to learn the language, but if that is not the case then there is no need to bother with Galician. Across Alava, Guipuzoca and Vizcaya there are about one million speaks of Basque. The Basque language has no clear link to any other existing languages and is a real puzzle to lingusits. If you decide to tackle Basque then you certainly need patience, and be willing to put in the hard work.
In the regions with their own languages you can get by with Spanish only, but it is worth your while trying to learn some words in the local tongue. Good luck with your Spanish studies!
