Notwithstanding its early origins and its importance for the history of Hebrew linguistics, the Karaite grammatical tradition has received insufficient scholarly attention, mainly due to the scarcity of reconstructed primary sources emanating from this school of Hebrew grammar. This book reconstructs from unpublished manuscripts a medieval Karaite treatise on the grammar of Biblical Hebrew in Judaeo-Arabic Kitāb al-ʿUqūd fī Taṣārīf al-Luġa al-ʿIbrāniyya and studies verbal morphological theories expressed in this and related Karaite works. Furthermore, the book examines Karaite approaches to the verbal classification as well as didactic tools used in Karaite pedagogical grammars.
