These languages are disappearing at a rapid rate In fact, we are seeing the greatest language loss ever. Because most of these languages have no written form, there are no books. As a consequence, students are not taught them at school and do not have even an elementary knowledge of them As old people die, the language dies with them. Researchers are trying to record these languages before they disappear. However, most of them exist in remote places, and unfortunately many of them are disappearing without trace. Some experts predict that half of the languages spoken today will be gone by the end of the century.
