In this study on relative pronouns and relative sentences in Assyrian, Kraetzschmar begins with the origin and demonstrative use of relative pronouns, noting the primary position of Sa as a genitive and a preposition. Kraetzschmar also addresses relative sentences without Sa. He also addresses the conjunctive relative sentence in Akkadian, considering subjective, objective, and sentences with time and syllogistic elements. Although a technical study, this exploration into a key form of expression in the burgeoning era of Akkadian studies will still find a place in libraries of specialists in Mesopotamian languages.
