On the surface, society in Democratic Kampuchea was strictly egalitarian. The Khmer language, like many in Southeast Asia, has a complex system of usages to define speakers' rank and social status. These usages were abandoned. People were encouraged to call each other "friend", or "comrade" (in Khmer, មិត្ដ mitt), and to avoid traditional signs of deference such as bowing or folding the hands in salutation.
Language was transformed in other ways. The Khmer Rouge invented new terms. People were told they must "forge" (lot dam) a new revolutionary character, that they were the "instruments" (opokar) of the Angkar, and that nostalgia for pre-revolutionary times (chheu satek arom, or "memory sickness") could result in their receiving Angkar's "invitation" to be deindustrialised and to live in a concentration camp.
