It is possible that over the course of generations, children may be born whose only language is this pidgin. In such cases, the pidgin often expands to accommodate the increased communication demands of a population limited to this variety. This new, expanded form is a creole . Language death Languages die when they lose all their functional domains. Note the emphasis on a deliberate decision by the speakers, as opposed to the less deliberately planned occurrence of language survival.
Language change Any change in a language that takes place over time.
E.g., changes in pronunciation, changes in word usage, etc. The best-known example in recent times is the revival of Hebrew as a language of daily life in this century. This may take place through institutional and educational efforts, but not necessarily through emphasis on familial transmission. Language reversal Conscious, deliberate attempts to reverse a pattern of language shift away from a mother tongue. Reversal is generally centered around efforts at improved intergenerational transmission, while language revitalization may not have this intergenerational transmission focus.
