There are few linguistic phenomena that have seduced linguists so skillfully
as grammatical case has done. Ever since Panini (4th Century BC), case has
claimed a central role in linguistic theory and continues to do so today.
However, despite centuries worth of research, case has yet to reveal its most
important secrets. This book offers breakthrough explanations for the
understanding of case through agent-based experiments in cultural language
evolution. The experiments demonstrate that case systems may emerge because
they have a selective advantage for communication: they reduce the cognitive
effort that listeners need for semantic interpretation, while at the same time
limiting the cognitive resources required for doing so.
