All cultures have their own distinct identity, such as music, dance, food, attire, language.
Language is probably the most important aspect of any culture. Language gives culture, a unique identity, something which is so unique that only people of that culture identity themselves with that language. There are thousands of languages in this world. From well educated secular Europeans to the Tribal living in the deepest jungles of Africa or South America, each culture with their own unique language. We have pre conceived notions about languages, such as we tend to think that the language which has a written history is more advance than others.
