This volume brings together 22 contributions to the study of Arabic dialects, from the Maghreb to Iraq by authors, who are all well-known for their work in this field. It underscores the importance of different theoretical approaches to the study of dialects, developing new frameworks for the study of variation and change in the dialects, while presenting new data on dialects (e.g., of Jaffa, Southern Sinai, Nigeria, South Morocco and Mosul) and cross-dialectal comparisons (e.g., on the feminine gender and on relative clauses). This collection is presented to Manfred Woidich, one of the most eminent scholars in the field of Arabic dialectology.
