We now know that linguistic change does not operate in such an across-the-board manner. Some speakers… — David Crystal

For a language is really alive only as long as there is someone to speak it to. When you are the only one left, your knowledge of your language is like a repository, or archive, of your people’s spoken linguistic past. If the language has never been written down, or recorded on tape—and there are still many which have not—it is all there is. But, unlike the normal idea of an archive, which continues to exist long after the archivist is dead, the moment the last speaker of an unwritten or unrecorded language dies, the archive disappears for ever. When a language dies which has never been recorded in some way, it is as if it has never been.

Language death is a terrible loss, to all who come into contact with it: `Facing the loss of language or culture involves the same stages of grief that one experiences in the process of death and dying.”‘ We do not have to be members of an endangered community to sense this grief, or respond to it. Anyone who has worked with these communities, even over a short period, knows that it is a genuine insight, well justifying the dramatic nature of the analogy. And it is this keen, shared sense of loss which fuels the motivation and commitment of linguists, community groups, and support organizations in many parts of the world.

Language death is like no other form of disappearance. When people die, they leave signs of their presence in the world, in the form of their dwelling places, burial mounds, and artefacts – in a word, their archaeology. But spoken language leaves no archaeology. When a language dies, which has never been recorded, it is as if it has never been.
