Arabic is the language of most of the population of our planet. It is the official language in 22 countries, spoken by over 250 million people. It is also widely used in many Islamic countries, because it is an Islamic spiritual language - one of the largest religions in the world. Another reason is because the Arabic is one of the oldest languages in the world, giving rise to many others, there is a theory which says that "Arabic is the origin of languages," those who believe in this theory, the fact the Arabs can easily pronounce any letter in any language in the world and on the other hand many non-Arabs is very difficult to pronounce certain Arabic letters that do not exist in their native languages.
I believe besides being one of the more developed countries that there is, England is vital center of a pop culture a lot influential in Europe and worldwide. The English, perhaps the most versatile language of planet has much to do with it. So, dominates about the language is more open anywhere. But I must mention that today, Spanish is spoken by over 300 million people around the world. It is the first official language in South and Central America, with the exception of Haiti, Suriname, Guyana and Brazil. Also, Spanish is spoken by almost 40 million Hispanic in Spain and several Spanish Islands in the Mediterranean and the Atlantic Ocean.
