The Thesaurus Linguae Latinae is a comprehensive dictionary of ancient Latin. It is compiled on the basis of all Latin texts preserved from antiquity (up to 600 AD), both literary and non-literary. It provides information on the etymology of Latin words and their survival in the Romance languages. The thesaurus offers a comprehensive, richly documented presentation of the possibilities and history of each Latin word – not only for Latinists, but also for classical scholars of various disciplines as well as for neighbouring disciplines.
