Causes

Cultural Assimilation: One major cause of languages going extinct is through assimilation. A language can become lost when a minority group speaking a small language begins using the dominant group of the main country's language. Many factors can be taken into account with this, such as a need to speak the dominant language in order to help advance the economy, or the need to communicate.

Linguistic Favoritism: Another major cause of languages going extinct could be seen in professional settings like school, work, media, a governmental setting, or community services. In these situations, it is not common that such a niche language would be utilized. When a more known language is favorited, the native language becomes less used and therefore loses its relevancy. It can especially be seen in these settings because these are habitual, daily responsibility activities that use the main language more often than the native language at home, for instance. 

Small Population & Generational Pass-down: Another major cause of languages going extinct revolves around the population of who speaks it. It makes it extremely vulnerable to extinction when it is less widely known, hence making it more difficult to spread the knowledge of the language. Furthermore, parents often do not pass down their native language to their children, which further prevents a language from spreading, causing risk of extinction.
