Paul Sidwell proposed the following classification of the Pearic languages in Sidwell (2009:137), synthesizing analyses from Headley (1985), Choosri (2002), Martin (1974), and Peiros (2004)[4] He divides Pearic into two primary branches (Pear and Chong), with Chong being further divided into four groups.
