Morris Swadesh (January 22, 1909 - July 20, 1967) was an Americanlinguist. Swadesh studied with Edward Sapir. He is famous for compiling the often varied Swadesh list, a list of common words which are essential to most languages, and used to determine the closeness of any pair of languages by so-called lexico-statistical techniques. For his proposal to use this list to compute the time-depth of languages, see glottochronology.

A Swadesh list is a prescribed list of basic vocabulary developed by Morris Swadesh in the 1940-50s, which is used in glottochronology (lexicostatistical dating). ... Glottochronology was a linguistics method used to estimate the time of divergence of two related languages. ...
Swadesh was married to linguist Mary Haas. Mary Rosamund Haas (born January 12, 1910; died May 17, 1996) was a linguist who specialized in North American Indian languages, Thai, and historical linguistics. ...
Swadesh’s contribution was to develop a set of principles to help the phonologist discover phonemes on the basis of the distribution of sounds in a given language.
Even more controversially, Swadesh claimed that the “decay” of basic vocabulary could be used for 8220;glottochronology,”; the dating of ancestor languages analogous to determining the age of fossils on the basis of radioactive decay.
Swadesh came to believe that basic vocabulary decays with a rate of 14 percent over 1000 years, so languages would retain on average about 86 percent of their basic vocabulary over this time span.
