Morris Swadesh himself created several versions of his list. He started with a list of 215 meanings (falsely introduced as a list of 225 meanings in the paper due to a spelling error), which he reduced to 165 words for the Salish-Spokane-Kalispel language. In 1952 he published a list of 215 meanings, of which he suggested the removal of 16 for being unclear or not universal, with one added to arrive at 200 words. In 1955 he wrote, "The only solution appears to be a drastic weeding out of the list, in the realization that quality is at least as important as quantity...Even the new list has defects, but they are relatively mild and few in number." After minor corrections the final 100-word list was published posthumously in 1971 and 1972.
