The Indo-European Lexical Cognacy Database (IELex) is an initiative of the Evolutionary Processes in Language and Culture research group to make available a database of cognate judgements in the Indo-European languages. The provenance of every lexeme and every cognate judgement in the database is recorded and available for review.
