The Urra=hubullu (𒄯𒊏 𒄷𒇧𒈝 ur5-ra — ḫu-bul-lu4) is a major Babylonian glossary or "encyclopedia".[1] It consists of Sumerian and Akkadian lexical lists ordered by topic.[2][3] The canonical version extends to 24 tablets, and contains almost 10,000 words.[4] The conventional title is the first gloss, ur5-ra and ḫubullu meaning "interest-bearing debt" in Sumerian and Akkadian, respectively. One bilingual version from Ugarit [RS2.(23)+] is Sumerian/Hurrian rather than Sumerian/Akkadian.
