Dialectology

Dialectology (from Greek διάλεκτος, dialektos, "talk, dialect"; and -λογία, -logia) is the scientific study of linguistic dialect, a sub-field of sociolinguistics. It studies variations in language based primarily on geographic distribution and their associated features. Dialectology deals with such topics as divergence of two local dialects from a common ancestor and synchronic variation. Dialectologists are ultimately concerned with grammatical, lexical and phonological features that correspond to regional areas. Thus they usually deal not only with populations that have lived in certain areas for generations, but also with migrant groups that bring their languages to new areas (see language contact). Commonly studied concepts in dialectology include the problem of mutual intelligibility in defining languages and dialects; situations of diglossia, where two dialects are used for different functions; dialect continua including a number of dialects of varying intelligibility; and pluricentrism, where a single language has two or more standard varieties. Hans Kurath and William Labov are among the most prominent researchers in this field. In London, there were comments on the different dialects recorded in 12th-century sources, and a large number of dialect glossaries (focussing on vocabulary) were published in the 19th century. Philologists would also study dialects, as they preserved earlier forms of words. In Britain, the philologist Alexander John Ellis described the pronunciation of English dialects in an early phonetic system in volume 5 of his series On Early English Pronunciation. The English Dialect Society was later set up by Joseph Wright to record dialect words in the British Isles. This culminated in the production of the six-volume English Dialect Dictionary in 1905. The English Dialect Society was then disbanded, as its work was considered complete, although some regional branches (e.g. the Yorkshire Dialect Society) still operate today.
