British English was the language that had the greatest influence on modern American English. Therefore, it is important to introduce the features of British English. As we know from history, the Germanic tribes, namely the Angles, Saxons and Jutes, invaded Britain and drove away the Celtic language already spoken there. This is how Old English was developed. It is quite difficult to understand this even for contemporary native English speakers. The next step in the development of English was the Norman invasion in 1066 which brought the French language, spoken by royalty over the following centuries until the English language became dominant again in the 14th century. . This period is called Middle English. With a major vowel shift, a change in pronunciation, and the invention of printing, English spelling and grammar were fixed. This period is called Early Modern English. Since the beginning of the 19th century we have been talking about Late Modern English, influenced mainly by the Industrial Revolution and the fact that the British Empire conquered much of the world, which has had an impact on the status of English today. as the most widespread language. Although British and American English have separated and developed on their own, in some American dialects we can hear the influence of the languages ​​of the British Isles. The mountain dialects or, in other words, the Appalachian dialects serve as a very good example. These type of Southern dialects are considered more guttural and as it sounds "should be classified as archaic". [online] and how some linguists assume that today's Appalachian dialect is "actually a kind of Elizabethan Scots-English.´ [online]From the first moment...... half of the article ......and for concretize the regional dialects and see their history and how they have developed over the past decades and what it is like with these dialects today We can start with a statement from the book A History of English Language by Albert C. Baugh who wrote: “All regions except eastern New England, metropolitan New York and the South are often regarded as constituting General America" ​​and "in this broader sense" General American covers about two-thirds of the land area of ​​the United States and contains two-thirds of the population total.´ (Baugh, 1957, p. 442) Therefore, we should base this chapter precisely on this quote from Baugh. It is certainly not so simple to divide all the American varieties into four categories but we must consider the complexity of the topic and unfortunately the length of the thesis does not allow us to explore all the accents in such depth.
