As the data employed for this monograph was collected, transcribed and analyzed by and with the help of many others over several decades, it would be impossible to thank all those who deserve thanks, and I would like to express my gratitude to them collectively. My thanks also to the many colleagues whose writings and personal input have stimulated my ideas or caused me to modify them.
I would like to mention specifically a number of people who have helped with this project: those who have reanalyzed some of their data for me with certain issues in mind–Tuc Ho-Dac, Jim Hlavac and Lin Zheng; those who have assisted with the analysis of particular data–Marguerite Boland, Tibor Endrody, Paola Cassia, Sue Fernandez and especially Sandra Kipp; Alexandra Aikhenvald, Salikoko Mufwene and Sandra Kipp, who have generously given up their time to read and comment on the manuscript; those who have kindly read and advised me on sections of the manuscript–Kees de Bot, Pim Levelt, Salikoko Mufwene, Leslie and Marianne Bodi, Irene Donohoue Clyne, Jim Hlavac and Petek Kurtboke; those who have helped with the production of this book–Andrew Winnard, the patient Linguistics editor, and his colleagues at Cambridge University Press, Kylie Martin, Felicity Grey who compiled the indexes and especially Anya Woods for her technical and editorial assistance. My thanks are also due to Salikoko Mufwene, the series editor, for his kind and helpful advice. Any imperfections remaining are the result of mine, and many of the above will be delighted that this task is finally completed.
I am also grateful to the Australian Research Council for financial assistance for this and earlier research projects.
