Khmer, also known as Cambodian, is spoken by some 7 million people living in Cambodia where about 90 percent of the population speak it as a first or second language. Khmer is the official language of Cambodia and is used in most social contexts including government administration, education at all levels, and in the mass media. Regional differences are slight and normally mutually intelligible. Based on the dialect of the capital city of Phnom Penh, Modern Khmer is used throughout the nation and widely understood by its inhabitants. Much Khmer vocabulary used in literature, the military, and administration is borrowed from Sanskrit, or Pali. Due to years of French colonial rule, numerous French words have been incorporated into the language as well. A committee was established during the 1960s with the responsibility of creating neologisms using native linguistic devices instead of borrowing from foreign languages. Later, the reign of the Khmer Rouge also left a significant linguistic legacy by expunging all features that reflected inequality of social status.
