This is the second revised edition of the first up-to-date, and complete grammar of Egyptian Aramaic as presented in texts of Egyptian provenance dating from the middle of the first millennium B.C.E. and as edited by B. Porten and A. Yardeni in their Textbook of Aramaic Documents from Ancient Egypt (Jerusalem, 1986-1999). The grammar covers not only the phonology and morphology, but contains a substantial section on morphosyntax and syntax. It is a descriptive grammar enriched with the expert knowledge and familiarity of one of the co-authors with the contents and background of the texts in question. It is meant to replace P. Leander's Laut- und Formenlehre des Ägyptisch-Aramäischen (1928), but also supplements it substantially, because it had no syntax. Due to the utmost importance and interest of these ancient texts, this grammar is a vade mecum for every Aramaist, Semitist and Historian in the field.
