The current list represents a modified version of Swadesh 1955 100 with twelve substitutions. The pronouns and demonstratives found in Swadesh-1955-100 were omitted and replaced with the concepts denoting simple actions (e.g. SING, VOMIT) and natural phenomena (e.g., WIND, SNOW, SKY). The resulted list was used in the reconstruction of the Uto-Aztecan language tree based on the investigation of cognate sets in the selected thirty-two languages.
