jats:titleAbstract</jats:title> jats:pJudaeo-Arabic manuscripts with complete vocalisation are rare, a problem which makes reconstructing the pronunciation of the medieval language challenging. This study presents an edition of a Judaeo-Arabic translation of Ecclesiastes from the Cairo Genizah with full Tiberian vocalisation. This manuscript exhibits noteworthy features of dialectal medieval Arabic and a palaeographic style which places it in twelfth-century Egypt-Palestine. The transcription system provides specific evidence for the pronunciation of a type of medieval Judaeo-Arabic, while the translation offers a window into the culture of popular Bible translations and scribal activity in the medieval Middle East.</jats:p>
