This book is a compendious grammar of the Aramaic dialect in which the ancient Samaritan literature is written. In a large measure this dialect is still used in the synagogal service of the community. As a Lehrbuch it is aimed at students interested in learning this dialect which flourished, along with the Talmudic Aramaic of Palestinian Judaism and Christian Palestinian Aramaic, during the Roman and Byzantine period. As such, the book presupposes a certain measure of familiarity with Hebrew. Some basic knowledge of any Aramaic dialect may be of great help as well. The material that forms the basis of this grammar is drawn from Z. Ben-?ayyim's publications, mainly from his edition of the liturgy, as recited in the synagogue (LOT IIIb), and from his translated and annotated edition of the Samaritan Midrash.
