Dead languages.

A dead language is a language that is no longer spoken or used for regular communication. Many ancient languages, such as Latin and Sanskrit, are considered dead languages because they are no longer spoken as a first language by any community. However, these languages are often studied and used in scholarship, literature, and religious rituals.

Other dead languages include Old English, Old Norse, and Classical Chinese. These languages were once widely spoken, but they have since fallen out of use and are now primarily studied by historians, linguists, and scholars of literature and culture.

There are also many smaller languages that have become extinct, either because the communities that spoke them have died out or because they have been absorbed into larger languages.

It is important to preserve and study dead languages as they can provide valuable insights into the history and culture of the societies that spoke them.
