Language plays a unique role in capturing the breadth of human diversity. We are constantly amazed by the variety of human thought, culture, society, and literature expressed in many thousands of languages around the world. We can find out what people think only through their language. We can find out what they thought in the past only if we read their written records. We can tell future generations about ourselves only if we speak or write to them. If we want other civilizations in space to learn about us we send them messages in dozens of our planet's six thousand languages.

The main purpose of this website is to provide information about the language families of the world and their most important and populous members, including their history, status, their linguistic characteristics, and their writing in as simple and concise a way as possible. We base this website on the belief that all languages have evolved from the need of human beings to express their thoughts, beliefs, and desires, that all languages meet the social, psychological, and survival needs of people who use them. In this sense, all languages, no matter how small and remote, are equal. All equally deserve study because all of them provide valuable insights into human nature.
