( Language change)
Language change is the manner in which the phonetic, morphological, semantic, syntactic, and other features of a language are modified over time. All languages are continually changing. At any given moment the English language, for example, has a huge variety within itself, and this variety is known as synchronic variation. From these different forms comes the effect on language over time known as diachronic change. Two linguistic disciplines concern themselves with studying language change historical linguistics and sociolinguistics. Historical linguists examine how a language was spoken in the past and seek to determine how present languages derive from it and are related to one another. Sociolinguists are interested in the origins of language changes and want to explain how society and changes in society influence language. All languages are constantly changing. The causes are many and varied. The constant influx of new words in the English language would make it an obvious choice of investigation into language change, although it is difficult to define precisely and accurately the vocabulary available to speakers of English. Throughout its history English has not only borrowed words extravagantly from other languages but has re-combined and recycled them to create new meanings, whilst losing some old words. The study of lexical changes is the task of onomasiology. The sociolinguist William Labov famously recorded the change in pronunciation in a relatively short period in the American resort of Martha’s Vineyard and showed how this was the result of social tensions and processes.[1] Even in the relatively short time that broadcast media have been available, we can observe the difference between the ‘marked’ pronunciation of the newsreaders of the 1940s and the 1950s and the more neutral, ‘unmarked’ pronunciation of today. The greater acceptance and fashionability of regional accents in the media may also reflect a more democratic, less formal society.
