It was in the course of 1980 that it dawned upon several friends and colleagues of Manfred Bierwisch that a half century had passed since his birth in 1930. Manfred's youthful appearance had prevented a timely appreciation of this fact, and these friends and co11eagues are, therefore, not at ali embarrassed to be presenting him, almost a year late, with a Festschrift which willleave a trace of this noteworthy occasion in the archives of linguistics. It should be realized, however, that the deIay would have easily extended to 1990 if alI those who had wanted to contribute to this book had in fact written their chapters. Under the pressure of actuality, several co11eagues who had genu- ineIy hoped or even promised to contribute, just couIdn't make it in time. Still, their greetings and best wishes are also, be it tacitly, expressed by this volume. Especia11y important for the archives would be a record of the celebrated one's works and physical appearance. For the convenience of present and future generations this Festschrift contains a bibliography of Manfred Bierwisch's scientific publications, which forms a chapter in itself. The frontispiece photograph was taken unawares by one of our accomplices. The title of this Festschrift may alIow for free associations of various sorts.
