Normally the transition from a spoken to an extinct language occurs when a language undergoes language death while being directly replaced by a different one. For example, some Native American languages were replaced by English, French, Portuguese, Spanish, or Dutch as a result of colonization.
The majority of the languages in the world are unwritten and many of them are disappearing. About 1/2 of the world's languages are no longer spoken by children. This is the first step in the extinction of a language. About 2,000 languages now have less than 1,000 speakers. The most threatened are the indigenous languages of Australia and the Americas.
