In general, the Norman and French borrowings concerned the fields of culture, aristocratic life, politics and religion, and war whereas the English words were used to describe everyday experience. When the Normans arrived in England, their copyists wrote English as they heard it, without realising the peculiarities of the relationship between Anglo-Saxon pronunciation and spelling and so the spelling changed. There appeared different regional Modern-English written dialects, the one that the king chose in the 15th century becoming the standard variety.
