The “Thesaurus Linguae Aegyptiae” (TLA) is an open access website and is the main publication platform for the texts and their linked vocabulary of the research project “Structure and transformation in the vocabulary of the Egyptian language”, that is jointly conducted by the Berlin-Brandenburg Academy of Sciences and Humanities (BBAW) and the Saxon Academy of Sciences and Humanities at Leipzig (SAW). The website was originally designed and developed for the projects “Dictionary of Ancient Egyptian” (BBAW, 1993–2012, and SAW, 1999–2012) and “Demotic Text Database” (Academy of Sciences and Literature in Mainz, 2001–2012) that went online in 2004. It contains a wide variety of ancient Egyptian texts written in hieroglyphs, hieratic and Demotic. The database can be consulted starting from individual words (in Egyptian, or in German and English translation) or from the entire text. It also enables the production of word indexes and the execution of statistical functions.

The TLA in its current version from 2015 is the largest Egyptian text database in the world and comprises 1.4 million text words. Apart from the texts of the Academy projects, it also includes many texts provided by other researchers and research institutions in Germany and from abroad: North Rhine-Westphalian Academy of Sciences and Arts (Bonn Book of the Dead project), Academy of Sciences and Humanities in Göttingen (Edfu Temple project) and individual researchers at the Universities of Leipzig (Digital Heka project), Leuven (Leuven Online Index of Ptolemaic and Roman Hieroglyphic Texts) und Prague (Middle Kingdom Biographies).

A new version of the TLA, including all new texts entered into the database between 2015 and 2020, is being prepared in a new design environment. Important new features of this will be the display of the hieroglyphic encoding and the grammatical annotation.
