Since the second edition of I.J. Gelb's Old Akkadian Writing and Grammar in 1961, which is still the standard grammar of Old Akkadian to this day, a significant number of new texts from the Old Akkadian period has been discovered and important improvements have been made regarding the analysis of Old Akkadian and Early Semitic grammar - particularly phonology - and writing. The present volume seeks to update our understanding of the syllabically written textual material from the Sargonic period (2350-2100 BCE), which contains most of our evidence for the Akkadian used at this period. It consists of a detailed investigation of the Sargonic Akkadian syllabary, phonology and morphology, with specific focus on geographical and dialectal variations that are noticeable in this text corpus, but which have not yet been examined thoroughly. The grammatical investigation further compares specific linguistic features of this period with the two later Akkadian dialects, Babylonian and Assyrian, in order to establish the position of the individual sub-groups of Sargonic Akkadian within the dialect geography of Akkadian.
