Languages can definitely change and they can diverge. For example, Latin split up into the modern Romance languages: Portuguese, Spanish, Romanian, Galician, etc. This is less known, but languages can also converge: those languages are called creole. Some people argue that English is also similar to a creole: a mix of Germanic and French.
What is an endangered language? The world faces enormous challenges in maintaining language diversity. Of the more than 6,912 languages, half may be in danger of disappearing in the next several decades, although this figure cannot be verified. Endangered languages are languages that are on the brink of extinction, much like endangered species of plants or animals. A language is considered to be endangered when parents are no longer teaching it to their children, and it is no longer being actively used in everyday life. A language is considered to be nearly extinct when it is spoken by only a few elderly native speakers.
