(...) multa renascentur quae iam cecidere cadentque quae nunc sunt in honore vocabula, si volet usus, quern penes arbitriwn est et ins et norma loquendi. Horace, arspoetica, 60-72 [As the trees full of leaves change as years go by and the earliest are falling, so an older generation of expressions falls out of use. And new ones, just born, flourish and grow vigorous like youth itself. Many expressions will be born again that have become obsolete, and many will drop out of use that are now prominent - if usage wants it so. For with usage lies the judgement and the norm and the standard of language.] Translation by M.K. Preface Many people have contributed in one way or another to this book, which is a slightly revised version of my PhD thesis, submitted to the University of Freiburg in February 1999. I am particularly grateful to my supervisor Bernd Kortmann, whose support has been truly exceptional throughout this project. I would also like to extend my gratitude to Christian Mair, who took on the role of deputy supervisor. Their work and continual feedback have had a pervasive influence on this study, and without them, my interest in grammaticalization would probably never have been triggered in the first place. There are various other members in the department whom I would also like to thank. Their support is just one indicator of the stimulating and cooperative working environment I am privileged enough to be a part of. For discussions and valuable comments on earlier drafts, I would like to thank in particular Verena Haser, Marianne Hundt and Richard Matthews. Lieselotte Anderwald's company in the office was also of great benefit. We regularly exchanged ideas, research methods and home-made biscuits. I believe I was the main beneficiary, certainly as far as the biscuits were concerned! I wish to thank Lowri Williams and Neale Laker for discussions on (and occasional distractions from) emerging modals. Thanks are further due to Susanne Wagner for her help with the index and layout and also to Allison Felmy for spotting what I hope were the last couple of typos in the manuscript. I gratefully acknowledge a grant from the German Academic Research Council (DAAD) for a two-month research trip to the United States and heartfelt thanks go to Patricia Slatin for putting me up for several weeks in the Maybeck house on the Berkeley Hills. This research trip had a great impact on the direction of my project and enabled me to discuss my approach and several results with Douglas Biber, Joan Bybee and Elizabeth Traugott. For their interest, support and later comments on the manuscript, I am extremely grateful. Elizabeth Traugott has become the co-editor of this book, and her comments were of great use during the revisions. By granting me access to the unpublished ARCHER corpus at Flagstaff, it was Douglas Biber who made it possible for me to include quantitative long-term investigations in this study. His comments on Chapters 5 and 6 were also much appreciated. viii Preface In addition, I gratefully acknowledge a grant from the 'Friends of Freiburg University' for the trip to a symposium on 'Frequency Effects and Emergent Grammar' at Carnegie-Mellon University. Thanks go again to Joan Bybee for inviting me back and for her invaluable feedback on my paper. The discussions with Paul Hopper and other participants at the symposium proved to be most helpful for the present work too. This study has also profited from discussions at various other conferences and talks where preliminary results were presented. Thanks go to the audiences at Albuquerque, Berkeley, Göttingen, lasi, Kassel and Växjö. I still owe Lucian Anderwald a couple of pints for scanning Peter Trudgill's map of English modern dialects onto the computer, and I thank Peter Trudgill himself for allowing me to plot my distributions of emerging modals on his original map. Special thanks also go to three old friends. Kathrin Lüddecke's comments on a draft chapter showed me the value of a classicist's views in the field of linguistics; Armin Schüler proved to be just the expert I needed on statistical matters; and the comments from my physics expert Dirk Rudolph led me to refine my ideas relating to the analogy between gravitation theory and developments in the English auxiliary domain. In addition, I would like to thank all those, too numerous to list, who were involved in the compilation of the corpora which I used. It goes without saying that - despite the great help which I have received from so many colleagues and friends - the remaining inadequacies are entirely my own. My dearest thanks, finally, go to Sandra, whose support and en- couragement have played more than an auxiliary role in the completion of this work. In the last three years haftas and gottas perhaps too seldom gave way to wannas. I dedicate this book to her.
