The series is dedicated to the comparative study of sign languages around the world. Individual or collective works that systematically explore typological variation across sign languages are the focus of this series, with particular emphasis on undocumented, underdescribed and endangered sign languages. The scope of the series primarily includes cross-linguistic studies of grammatical domains across a larger or smaller sample of sign languages, but also encompasses the study of individual sign languages from a typological perspective and comparison between signed and spoken languages in terms of language modality, as well as theoretical and methodological contributions to sign language typology.

Typological studies require a broad range of linguistic data from a variety of countries, especially developing nations whose languages are under-researched. This is especially challenging for investigations of sign languages, because there are no existing corpora for most of them, and some are completely undocumented. To examine three cross-linguistically fruitful semantic fields in sign languages from a typological perspective for the first time, a detailed questionnaire was generated and distributed worldwide through emails, mailing lists, websites and the newsletter of the World Federation of the Deaf (WFD). This resulted in robust data on kinship, colour and number in 32 sign languages across the globe, 10 of which are revealed in depth within this volume. These comprise languages from Europe, the Americas and the Asia-Pacific region, including Indonesian sign language varieties, which are rarely studied. Like other volumes in this series, this book will be illuminative for typologists, students of linguistics and deaf studies, lecturers, researchers, interpreters, and sign language users who travel internationally.
