readings were determined by the analysis of the bilingual cuneiform Akkadian-Linear Elamite (Louvre Museum), by and . Two words with similar endings were identified in the beginning of the inscription in the known Akkadian cuneiform (the words "Inshushinak" and "Puzur-Inshushinak" ), and correspondingly similar sets of signs with identical endings were found in the beginning of the Elamite part ( and ), suggesting a match. This permitted a fairly certain determination of about ten signs of Linear Elamite: Pu-zu-r shu-shi-na-k, King Puzur-Inshushinak. I-n-shu-shi-na-k, God Inshushinak. Further efforts were made, but without significant success. Silver beakers Additional readings were proposed by CNRS associate researcher François Desset in 2018, based on his analysis of several silver beakers that were held in a private collection, and only came to light in 2004. Desset identified repetitive sign sequences in the beginning of the inscriptions, and guessed they were names of kings, in a manner somewhat similar to Grotefend's decipherment of Old Persian cuneiform in 1802–1815. Using the small set of letters identified in 1905–1912, the number of symbols in each sequence taken as syllables, and in one instance the repetition of a symbol, Desset was able to identify the only two contemporary historical rulers that matched these conditions: Shilhaha and Ebarat, the two earliest kings of the Sukkalmah Dynasty. Another set of signs matched the well-known God of the period: Napirisha. This permitted the determination of several additional signs: Shi-l-ha-ha, Shilhaha, second king of the Sukkalmah Dynasty. E-ba-r-ti, Ebarat II, founder of the Sukkalmah Dynasty. Na-pi-r-ri-sha, God Napirisha. Reading texts As of 2020, Desset announced that he and his international team had completed a proposed decipherment of all known inscriptions in Linear Elamite, through deductive work based on the confrontation of known Elamite vocabulary and the recently determined additional letters, and through the analysis of the standard contents of known Elamite texts in cuneiform. Their near-complete decipherment of the script was published in 2022. New readings include: Ha-ta-m-ti, endonym for Elam. Writing system Classification argue that Linear Elamite is an alpha-syllabary, which would make it the oldest known purely phonographic writing system. However, they admit that some logograms may have been used, although only rarely and not systematically, arguing that Elamite scribes rejected logographic writing in the 3rd millennium BCE. Other researchers, such as the linguist Michael Mäder, dispute this, arguing that only around 70 percent of Linear Elamite characters are likely to be
