The multifaceted and heterogeneous category of common ground is central to theories of pragmatics, sociolinguistics, discourse and context. This book addresses current approaches to common ground from the novel perspective of lexical markers. The edited volume falls in two parts. The first part addresses the relationship between mechanisms of grounding and reference to common ground. The second part examines different types of common ground. It is shown that the investigation of lexical markers provides a novel perspective for investigating the relationship between grounding, common ground and common grounds. Contributions are by Sherri L. Condon and Claude G. Cech, Anita Fetzer, Kerstin Fischer, Francois Nemo, Thanh Nyan, Moeko Okada, Carlos Rodriguez Penagos, Karin Pittner and Thora Tenbrink.
