Spanish is an official language of around twenty countries and is spoken by over 400 million people around the world. Spanish, like many of the other languages spoken around the world, has several variations corresponding to the different regions where it is spoken. The distinctness between the Spanish dialects and those of other dialects is that Spanish dialects do not have many grammatical differences, regardless of the major variations between their vocabulary, intonation and pronunciation. The Spanish dialects spoken in North America have major differences between those spoken in Spain, as is the case with the Spanish dialects spoken in Latin America.

Some of the major differences as far as pronunciations are concerned involve the putting the letter s at the ends of words. In Latin America, these endings are silent, while in major parts of Spain, they are vocalized. In several parts of Latin America, the letter j at the beginning of a word is pronounced as an h in the English word hope, which is not the case in the Spanish dialects spoken in Spain or North America. Words ending with the letter n are pronounced as in the English word Zen when speaking in the Spanish dialects used in Latin America and Spain, while the n in the same situation is pronounced as ng in the English word song in Spanish dialects spoken in the United States. In major parts of Latin America, the phoneme, /th/ has been completely merged with /s/. Because of this, the Spanish dialects found in Latin America have a few words which have same phonetics with different meaning and spelling. This is not the case with the other Spanish dialects spoken in other parts of the world.

As for the variations in grammar of the different Spanish dialects, the pronoun vos, which is the second person plural pronoun, is a common feature of the Spanish dialects spoken in Latin America. The transitive verb tutear is used with vos in the Latin American Spanish dialects. Similarly, Spanish dialects in Latin America have only one second person plural pronoun, that is, ustedes, while that in Spain has two ustedes and vosotros. In Latin American Spanish dialects, the verbs generally are in the simple past tense while those in Spain use the compound tense form to describe an action that has been completed in the past.

The different Spanish dialects spoken in various parts of the world include but are not limited to: Standard Spanish dialects, American Spanish dialects, Andalusian Spanish dialects, Canarian Spanish dialects, Castilian Spanish dialects, Caribbean Spanish dialects, Colombian Spanish dialects, Mexican Spanish dialects, Moroccan Spanish dialects, Panamanian Spanish dialects, Rioplatense Spanish dialects and Venezuelan Spanish dialects.
