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.
Linguists, however, do make a distinction between the two based on the concept of mutual intelligibility. Two languages where speakers can understand each other are considered dialects of the same language, whereas two languages where the speakers cannot understand each other are, indeed, separate languages.This often isn't black and white, since understand can be a hard criterion to pin down. language is a dialect with an army and navy. His point being that the difference between a language and a dialect was ultimately a political distinction and had little to do with linguistics per se.
