This is a concept list proposed by Sergej Yakhontov as an alternative to Swadesh 1955 100. In this list, 10 items from the original list were removed and 10 new items were added. The list was proposed much earlier than the source, apparently already in the beginning of the 1960ies (Djačok 2008), but Yakhontov never published his list officially. Note that there is a spelling error in the source of Starostin 1991: In the source, the second item is labelled «течь» («float») in Russian, although the alphabetical order suggests that «жечь» («burn tr.») was originally intended by the author.
