É (Cuneiform: 𒂍) is the Sumerian word or symbol for house or temple.
The Sumerian term É.GAL (𒂍𒃲,"palace", literally "big house") denoted a city's main building. É.LUGAL (𒂍𒈗,"king's house") was used synonymously. In the texts of Lagash, the É.GAL is the center of the ensi's administration of the city, and the site of the city archives.Sumerian É.GAL is the probable etymology of Semitic words for "palace, temple", such as Hebrew היכל heikhal, and Arabic هيكل haykal. It has thus been speculated that the word É originated from something akin to *hai or *ˀai, especially since the cuneiform sign È is used for /a/ in Eblaite.
