Judging from the number of items, it is clear that this list is a merger of the two concept lists proposed by Swadesh in Swadesh 1952 200 and Swadesh 1955 100. There are, however, some deviations from Swadesh's original concept labels, and these again show that the list of Gudschinsky 1956 200 may have served as the base list for 200 of the 207 items. Since the list appears in an influential questionnaire for linguistic fieldwork, it can be expected that the impact of this list on fieldworkers was much higher than the impact of the original concept lists proposed by Swadesh.
