Why do languages die?
Obviously a language dies if all of its speakers die. Catastrophic natural disasters can decimate or wipe out small communities in isolated areas, leading to a sudden and irreversible extinction of their language. Moreover, a language dies if its speakers are scattered in such a way as to break up the language community. Political, social and economic threats also take part in language death. More commonly languages die through cultural change and language replacement, by assimilation to a "dominant" culture and language. This process is broad and complex, but one major factor is negative attitudes to a language, both in government policy and local communities.
