Celebrity Solstice was, at 122,000 GT, the largest ship to be built at a German shipyard, but this record was surpassed by the Disney Dream, a 128,000 GT cruise ship of the Disney Cruise Line.
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.
A mixed language is a language that arises through the fusion of usually two source languages, normally in situations of thorough bilingualism (Meakins, 2013), so that it is not possible to classify the resulting language as belonging to either of the language families that were its sources.
