The Linguistics Research Center (LRC) at The University of Texas at Austin was founded in 1961 by Winfred P. Lehmann, and in the early years focused on machine translation. The most successful, commercially available, rule-based machine translation system, known as METAL, was developed here, beginning in the 1960’s and continuing well into the 1990’s. Another major research area of the LRC is Indo-European linguistics; our website maintains an extensive lexicon of Proto-Indo-European root words (etyma) and their reflexes in descendant languages. Free online language lessons are also available for several Indo-European languages, as well as a collection of early Indo-European texts, and online books about Indo-European languages and historical linguistics.
