This book offers an in-depth corpus-based description of written Sri Lankan English. In comparison to British and Indian English, lexical and lexicogrammatical features of Sri Lankan English are analysed in a complex corpus environment comprising data from the respective components of the International Corpus of English, newspapers and online sources to explore the status of Sri Lankan English as a variety in its own right. The evolution of Sri Lankan English is depicted against the background of historical as well as sociolinguistic considerations and allows deriving a fine-grained model of the emergence of distinctive structural profiles of postcolonial Englishes developing in a multitude of norm orientations. The book also offers more general sociolinguistic perspectives on the dynamics of postcolonial Englishes world-wide and on the inextricable link between language and identity.
