Languages carry vibrations from people's emotional states or feelings. If the people are feeling haughty, the language will change with it, like how the British accent diverged from the American accent. When people live apart for a very long time, or when they are isolated, they tend to form their own dialect, which grows into a language if lack of contact is maintained. This difference in dialect might come about because of the founder effect, where people with different personality speak a bit differently; it might also be affected by the environment, like whether the region is hot or cold, humid or dry, sunny or cloudy, mountains or plains.
