In the third edition of A Grammar of Akkadian, changes have been made in the section on the nom i n al morpheme -an (20.2) and the sections on the meaning of the D stem (24.3) and the Gt stem (33.1(b)); these revisions reflect recent scholarship in Akkadian grammar. Other changes include minor revisions in wording in the presentation of the grammar in a few other sections; a number of new notes to some of the readings; additions to the glosses of a small number of words in the lesson vocabularies (and the Glossary and English-Akkadian word list); and updates of the resources available for the study of Akkadian, and of the bibliography. A new appendix (F) has been added, giving Hebrew and other Semitic cognates of the Akkadian words in the lesson vocabularies. The pagination of the first and second editions has for the most part been retained, apart from the insertion of the new appendix and a few minor deviations elsewhere.
