This is an attempt by the authors to further specify the meanings of concept lists for the purpose of language comparison. They take the list of Starostin 1991 as a basis, which is itself a merger of the concept list proposed by Sergej Yakhontov and the 100-item list proposed by Swadesh (1955). This lists contains a total of 116 items, since the authors subdivided certain parts of the 110-item list in order to get a more precise definition of the concepts. Thus, the authors clearly distinguish between different kinds of «thin», depending on the shape of the object (be it flat or long).
