In the past two decades, the study of prepositions has grown steadily. The papers collected in this volume bring together the multifaceted perspectives on prepositions that have been developed in contemporary linguistics. Some papers mainly discuss syntactic (and morphological) aspects of prepositions; other papers predominantly focus on cognitive aspects. All the papers are, however, concerned with the semantics of prepositions. This volume evolved from a workshop on prepositions held at Hamburg University on June 26 and 27, 1998.
