14．Towards the end of Middle English，a sudden change in pronunciation started，with vowels （元音） being pronounced shorter and shorter．From the 16th century the British had contact with many people from around the world．This meant that lots of new vocabulary entered the language．The invention of printing also meant that there was now a common language in print．Books became cheaper and more people learned to read．Spelling and grammar became fixed，and the dialect of London became the standard．In 1604the first English dictionary came out．
