The dialects of Middle English are usually divided into three large groups: Southern (subdivided into Southeastern, or Kentish, and Southwestern), chiefly in the counties south of the River Thames; Midland (corresponding roughly to the Mercian dialect area of Old English times) in the area from the Thames to southern South Yorkshire and northern Lancashire; and Northern, in the Scottish Lowlands, Northumberland, Cumbria, Durham, northern Lancashire, and most of Yorkshire.
During the Norman occupation, about 10,000 French words were adopted into English, some three-fourths of which are still in use today. This French vocabulary is found in every domain, from government and law to art and literature – learn some. More than a third of all English words are derived directly or indirectly from French, and it's estimated that English speakers who have never studied French already know 15,000 French words.
