Spanish is spoken in Spain, Andorra, Argentina, Bolivia, Chile, Costa Rica, Dominican Republic, Ecuador, El Salvador, Guatemala, Equatorial Guinea, Honduras, Columbia, Cuba, Mexico, Nicaragua, Panama, Paraguay, Peru, Uruguay and Venezuela. It is a Romance language, very similar to Italian, Portuguese, Catalan, Latin and somewhat similar to French. A lot of people learn it because of its usefulness (particularly for Americans and travellers to South America), its culture and its sound, which is perceived as beautiful by many.
What to expect when studying Spanish: English speakers will find that Spanish spelling is very phonetic and easy to learn. The grammar is more complicated than e. g. English grammar or the grammar of South-East Asian languages, but easier than German or Slavic grammar, since there are no cases. Noun genders have to be reckoned with however.
Advice for learning Spanish: Always memorise the gender of a noun along with the noun itself. This is best done by associating a male person with every masculine word and a female person with every feminine word. Also be sure to look at word endings, since many of them have a close relation to the word's gender. And as with learning any language, try and refrain from translating everything from one language to another once you've reached an intermediate level. Try to think more of the meaning of the word and you'll be able to use the language better. Get advice valid for learning any language here.
