My experience of meeting people from various countries allows me to state that Spanish is the most beautiful language of all I've ever heard. Although the elements that form the language are very diverse, the basics of Spanish come from Latin (60% of the vocabulary).
Spanish or Castilian is a member of the Romance branch of Indo-European, descended chiefly from Latin and having much in common with its European geographical neighbors, and the fourth most widely spoken language in the world. It's the first language of about 352 million people and is spoken by 417 million including non-native speakers (estimated in 1999). Therefore, it's considered to be the second most important language (The first is English, of course) on Earth. The reasons are quite simple: wide usage in the USA, the surging birth rate in Spanish-speaking countries (Argentina, Bolivia, Chile, Colombia, Costa Rica, Cuba, Dominican Republic, Ecuador, El Salvador, Equatorial Guinea, Guatemala, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru , Puerto Rico, Spain, Uruguay, Venezuela, Western Sahara, Andorra, Belize, Gibraltar), the flourishing economies of those countries, the great Spanish influence on the world music industry etc.
Spanish has a two-gender system and about fifty conjugated forms for almost any verb, but small noun flexibility (declension) and a limited number of pronouns. Moreover, Spanish allows eliding pronouns when unnecessary.
As for syntax, the sentence word order is S-V-O, though some variations exist. Spanish uses prepositions and adjectives are generally coming after nouns.
Spanish has a phonemic stress system - a change of stress makes a word change its meaning. Spanish orthography is such that every speaker can guess the pronunciation from the written form.
