Welcome to The ASJP Database

The database of the Automated Similarity Judgment Program (ASJP) aims to contain 40-item word lists of all the world's languages. A lexical distance can be obtained by comparing the word lists, which is useful, for instance, for classifying a language group and for inferring its age of divergence.
