Book excerpt: The book provides an encyclopaedic overview of the language contact between Slavic languages and Romani in Eastern, South-Eastern and East-Central Europe. It is based on Yaron Matras’ pragmatic-functional approach to language contact and follows a new direction in Romani linguistics that conceives Romani as a subgroup of closely related languages rather than a single language. The central topics discussed in the book are: Slavic impact on Romani phonetics and phonology, morphology and syntax; forms and functions of Slavic verbal prefixes in Romani; Slavic impact on the Romani lexicon; Romani elements in the nonstandard lexicon of the Slavic languages; writing Romani with ‘Slavic’ alphabets.
