It is generally assumed that Creole languages form a separate category from the rest of the world's languages. The papers in this volume, written by internationally renowned scholars in the field of Creole studies, seek to explore more deeply this commonly held assumption by comparing the linguistic properties of specific Creole languages to each other and also to non-Creole languages. Using a variety of methodological and analytical approaches, the contributions to this volume show that the linguistic classification of Creole languages continues to be a topic of intense debate that requires the re-examination of the premises of linguistic typology. What is the linguistic motivation for considering that languages are related or unrelated? How and why do common linguistic properties arise? Are Creoles indeed exceptional? This volume examines these questions and provides a strong foundation for continued research into the phonological, morphological, syntactic and semantic features found in Creole languages. Most of these articles were previously published in the Journal of Pidgin and Creole Languages 26:1 (2011).
