The Most Common Letter in English is "E".

It was interesting to see a documentary about a language with a rich history of about 1000 years, but focusing on its recent influences. The Story of English displayed its importance to the modern world after centuries of being created. The world has seen many changes in society in just a mere century. These changes brought new ways of sharing and communicating between every corner of the world.
It seems that the english language has evolved into a universal language for many functions. It's the official language for aeronautical, and maritime communications. Such so, "So when an italian pilot, flying an italian plane, into italian airspace, contacts italian ground control speaking only in english." (The Story of English). Flying is one of the most common means of transportations and allows cultures from countries to interact between others. Because of so much diversity a common-spoken language was necessary for pilots and control towers to communicate.

Having the accessibility to travel and share, varieties of the english language are mixed up and evolved as people leave their past. Though what is the right variety of the english language. According to The Story of English, Oxford english is the correct way of speaking the language. I truly do not believe there is a correct way of speaking english. Well pronouncing words in a understandable way and with a proper syntax is a correct way of speaking, but there is no correct accent. The important aspect of speaking english is that it is understandable to whomever is trying to understand.
