Pearic languages are remnants of the aboriginal languages of much of Cambodia, but have dwindled in numbers due to assimilation. "Pear" is a pejorative term meaning 'slave' or 'caste'.
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) He divides Pearic into two primary branches (Pear and Chong), with Chong being further divided into four groups.
