This list was used for a phylogenetic investigation of the Uralic language family. According to the authors, it is a merger of several previously proposed lists, including Swadesh's list of Swadesh 1955 100 and Swadesh 1952 200 items and the Tadmor 2009 100. In their list, they provide mappings (though no labels) to these lists. For details on these mappings, see their notes in the appendix of the article.
