This volume collects twenty-nine published and unpublished papers by the linguist James Gair, considered the foremost western scholar of the Sri Lankan languages Sinhala and Jaffna Tamil. Ranging over thirty years, his work also considers issues in a variety of Indian languages, including Hindi, Marathi, Tamil, Malayalam, and Bengali. The collection reflects the wide range of Gair's interests, from morpho-syntactic questions to questions regarding historical and areal linguistics, especially language contact and diglossia, and extending to language acquisition. By collecting these papers and making them newly accessible, this volume will provide an important resource not only for scholars of these languages but for linguists interested in the theoretical issues Gair explores.
