the field of sociolinguistics: Multicultural London English: principal investigator, working with Paul Kerswill and others, in identifying and defining a new typological language variety, multiethnolect, spoken by young, working-class people in London as well as by multiethnic youth across Europe, including Scandinavia, the Netherlands, Belgium, Germany, and France. Adolescent Friendship Groups: Cheshire, Kerswill, Fox and Torgersen (2008) showed that adolescent ethnicity interacts with patterns of friendship to create dense, multi-ethnic "friendship networks" which determine an individual's "choice and degree of use of certain linguistic features". In addition, these researchers identified "a cluster of life-style indicators which seem to be shared by most of the individuals [identified] as potential linguistic innovators." Syntactic Variation: Through multiple variationist studies, Cheshire has shown how analysing the social distribution of a variable syntactic construction sheds light on the nature of pragmatic functions, which provides more insights into the social aspects of language use. Cheshire et al. have shown the syntactic variation is of a very different nature than phonological or morphological variation. 'Syntax is so central to the construction of discourse that we have to look beyond any superficial alternation to examine what speakers do with their grammar – in other words, to focus on social interaction'. Dialect Levelling: Cheshire, Kerswill, Williams, along with many others, have uncovered significant amounts of dialect levelling in Britain, i.e., "the replacement of local features by others with a wider geographical currency," through the increased use of non-standard variants in phonology, morphology and syntax occurring throughout the major urban centres of Britain. World English: Cheshire's edited volume on English around the World brings together varieties of English across 60 countries, covering such typologically distinct varieties as standard English, non-standard dialects, pidgins, creoles, and new Englishes, and describes how linguistic variation and change is happening on a far greater scale than has ever been seen in the world's linguistic history.
