Through time, variations appear within a language. Transmission of a language is self-perpetuating unless there is deliberate interference. However, it became important for humans to improve their social hierarchies and social status to advance personally. Thus, many people cultivate the right dialect with their phonological, grammatical and lexical features to make better than the rest and get accepted in new communities. An example of this phenomenon is the insistence of immigrants from Europe to speak American English when they decided to move to the United States. It is because they realized that speaking American English is the sign of acceptance in their new home country. Unexpectedly, third generation immigrants now want to get in touch with the language of their ancestors.
