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.
Latin, the language of science, at one time the lingua franca of the western world, a language shaped by culture and spread by conquest, is now considered a dead language.. It is no longer spoken as a native tongue by any group or culture but is rather left to classicists who study the world of classical antiquity.
