 | | To apply the technique, you take a list of basic vocabulary known as the Swadesh list after Morris Swadesh, the linguist who proposed glottochronology, and you translate it into the languages you are working with. |
 | | There are a number of variants of glottochronology, using vocabulary lists of different lengths, different rates of lexical change, and so forth, and a variety of difficulties in applying the technique, but the central problem is that the lexical replacement rate is not constant. |
 | | For example, the PIE word for "bear" (not on the Swadesh list, just a convenient example) is believed to be the ancestor of Latin ursus, Greek arktos, Sanskrit rkshas, Welsh arth (as in the name Arthur) etc. However, this doesn't show up in Germanic and Balto-Slavic. |
