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.
The term linguistic variation (or simply variation) refers to regional, social, or contextual differences in the ways that a particular language is used. Variation between languages, dialects, and speakers is known as interspeaker variation. Variation within the language of a single speaker is called intraspeaker variation. Since the rise of sociolinguistics in the 1960s, interest in linguistic variation (also called linguistic variability) has developed rapidly.
