Dialectal change and diffusion

Dialectal change and diffusion. The basic cause of dialectal differentiation is linguistic change.

Every living language constantly changes in its various elements. Because languages are extremely complex systems of signs, it is almost inconceivable that linguistic evolution could affect the same elements and even transform them in the same way in all regions where one language is spoken and for all speakers in the same region. At first glance, differences caused by linguistic change seem to be slight, but they inevitably accumulate with time e.g. compare Chaucers English with modern English. Related languages usually begin as dialects of the same language.

When a change an innovation appears among only one section of the speakers of a language, this automatically creates a dialectal difference. Sometimes an innovation in dialect A contrasts with the unchanged usage archaism in dialect B. Sometimes a separate innovation occurs in each of the two dialects. Of course, different innovations will appear in different dialects, so that, in comparison with its contemporaries, no one dialect as a whole can be considered archaic in any absolute sense. A dialect may be characterized as relatively archaic, because it shows fewer innovations than the others or it may be archaic in one feature only . 9, p.415 After the appearance of a dialectal feature, interaction between speakers who have adopted this feature and those who have not leads to the expansion of its area or even to its disappearance.

In a single social milieu generally the inhabitants of the same locality, generation and social class, the chance of the complete adoption or rejection of a new dialectal feature is very great the intense contact and consciousness of membership within the social group fosters such uniformity.

When several age groups or social strata live within the same locality and especially when people speaking the same language live in separate communities dialectal differences are easily maintained. The element of mutual contact plays a large role in the maintenance of speech patterns that is why differences between geographically distant dialects are normally greater than those between dialects of neighbouring settlements.

This also explains why bundles of isoglosses so often form along major natural barriers - impassable mountain ranges, deserts, uninhabited marshes or forests, or wide rivers - or along political borders. Similarly, racial or religious differences contribute to linguistic differentiation because contact between members of one faith or race and those of another within the same area is very often much more superficial and less frequent than contact between members of the same racial or religious group.

An especially powerful influence is the relatively infrequent occurrence of intemarriages, thus preventing dialectal mixture at the point where it is most effective namely, in the mother tongue learned by the child at home . 9, p.417 The fact that speech, in particular, can give such a clear answer to the question Where are you from? exercises a peculiar fascination, and the terms dialect and accent are a normal part of everyday vocabulary.

We can notice regional differences in the way people talk, laugh at dialect jokes, enjoy dialect literature and folklore and appreciate the point of dialect parodies. At the same time - and this is the paradox of dialect study - we can easily make critical judgements about ways of speaking which we perceive as alien. These attitudes are usually subconscious.

The study of regional linguistic variation is very important. The more we know about regional variation and change in the use of English, the more we will come to appreciate the individuality of each of the varieties which we call dialects, and the less we are likely to adopt demeaning stereotypes about people from other parts of the country. As for the United Kingdom until 1700 the small population was sparsely distributed and largely rural and agricultural, much as it had been in medieval times. From the mid-18th century, scientific and technological innovations created the first modern industrial state, while, at the same time, agriculture was undergoing technical and tenurial changes and revolutionary improvements in transport made easier the movement of materials and people.

As a result, by the first decade of the 19th century, a previously mainly rural population had been largely replaced by a nation made up of industrial workers and town dwellers. The rural exodus was a long process.

The breakdown of communal farming started before the 14th century and subsequently enclosures advanced steadily, especially after 1740, until a century later open fields had virtually disappeared from the landscape. Many of the landless agricultural labourers so displaced were attracted to the better opportunities for employment and the higher wage levels existing in the growing industries their movements, together with those of the surplus population produced by the contemporary rapid rise in the birth rate, resulted in a high volume of internal migration that took the form of a movement toward the towns.

Industry, as well as the urban centres that inevitably grew up around it, was increasingly located near the coalfields, while the railway network, which grew rapidly after 1830, enhanced the commercial importance of many towns. The migration of people especially young people, from the country to industrialized towns took place at an unprecedented rate in the early railway age, and such movements were relatively confined geographically.

Soon after World War I, new interregional migrations flow commenced when the formerly booming 19th-century industrial and mining districts lost much of their economic momentum. Declining or stagnating heavy industry in Clydeside, northeastern England, South Wales, and parts of Lancashire and Yorkshire swelled the ranks of the unemployed, and the consequent outward migration became the drift to the relatively more prosperous Midlands and southern England.

This movement of people continued until it was arrested by the relatively full employment conditions that obtained soon after the outbreak of World War II. In the 1950-s, opportunities for employment in the United Kingdom improved with government sponsored diversification of industry, and this did much to reduce the magnitude of the prewar drift to the south. The decline of certain northern industries - coal mining shipbuilding, and cotton textiles in particular - had nevertheless reached a critical level by the late 1960s, and the emergence of new growth points in the West Midlands and southwestern England made the drift to the south a continuing feature of British economic life. Subsequently, the area of most rapid growth shifted to East Anglia, the South West, and the East Midlands.

This particular spatial emphasis resulted from the deliberately planned movement of people to the New Towns in order to relieve the congestion around London. 4.
