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.
Causes which prevent or discourage speakers from using a language, such as: 1  Political repression. 2  Cultural/political/economic marginalization/hegemony. 3  Urbanization. 4  Intermarriage can also cause language endangerment, as there will always be pressure to speak one language to each other.
