The Thesaurus Linguae Aegyptiae is an online dictionary and text corpus of the Egyptian language developed by the Research Centre for Primary Sources of the Ancient World at the Berlin-Brandenburg Academy of Sciences and Humanities (BBAW) in Berlin, Germany.
Intended to be a complete documentation of the Egyptian lexicon, it encompasses varied meanings of words in different texts over 3000 years of linguistic history.
The dictionary is entirely based on primary source material, including inscriptions from temple walls, roads, tombs, papyri, and potsherds from religious, legal, administrative, and literary texts.
[1] The Thesaurus Linguae Aegyptiae is modelled and built upon the Wörterbuch der aegyptischen Sprache (English: Dictionary of the Egyptian Language) begun by Adolf Erman in 1897 at the Prussian Academy of Sciences.
In 1993, a project to update the dictionary began at the Berlin-Brandenburg Academy of Sciences and Humanities and created the Thesaurus Linguae Aegyptiae.
