There are more than 2,700 languages in the world. In addition, there are more than 7,000 dialects. A dialect is a regional variety of a language that has a different pronunciation, vocabulary, or meaning. The language in which a government conducts business is the official language of that country. 1 billion people speak English. That's 20% of the world's population. 400 million people speak English as their first language. For the other 600 million it's either a second language or a foreign language. There are more than 500,000 words in the Oxford dictionary. 80% of all English vocabulary comes from other languages.
