This article presents the first edition of an Old-Babylonian acrographic vocabulary excavated in the city of Ur. Although fragmentary and poorly preserved, this text provides interesting new aspects for the understanding of the so-called „dialects“ of Sumerian and of bilingual language teaching in general, and identifies lurû(m) „(man with a) thin/croaky voice“ as a (person with a) speech defect described as „Emesal“. In addition, it contains entries of business terminology known from the north Babylonian „Sippar Phrasebook“, the Old Babylonian „Forerunner“ of canonical Ura 1 and 2.
