DescriptionnAll languages change and vary over time and space. The study of language change and variation is the ‘core of the sociolinguistic enterprise’, and it has ‘a relatively short history’ (Chambers et al. 2002, p.1). Diachronic change occurs in which the phonological, lexical, syntactic, semantic, discourse, pragmatic, and other features of a language are modified over time. In addition, at any given moment, a language also has a variety within itself among different communities of its speakers, and this variety is known as synchronic variation. Lexical change and variation are among the most evident aspects of language change and variation. In this essay assignment, you are expected to do the following:nna.
