want to also add the position of London as an operational, cultural, financial, and defensive post ever since its creation as a city. Once the newly-called English were in operation, London became a center of commerce. Through London, as a port in front of the River Thames, loads of diverse cultural groups came in and out to make business.The location was prime for trade and exchange,and (as a linguist I can almost ascertain)that the process created its own unique lexicon.
Furthermore, as England expanded as an empire, it brought with it the lexicon of commerce, as well as the cultural gains that London (itself an entire personage far removed from England as a whole) brought with it.
It is not surprising, then, that English became such a powerful language due to the potential of connection that England's capital brought with it, and the influence it exercised in the nearby countries.
