EtymologyMain article: Name of Cambodia
Cambodia is the traditional English name, taken from the French Cambodge, while Kâmpŭchea , formerly the name of the country in English, is the direct transliteration, more faithful to the Khmer pronunciation. The Khmer Kampuchea is derived from the ancient Khmer kingdom of Kambuja (Kambujadeśa (Land of Kambuja). Kambuja or Kamboja is the ancient Sanskrit name of the Kambojas, an early tribe of north India, named after their founder Kambu Svayambhuva,[8] believed to be a variant of Cambyses. See Etymology of Kamboja.
"Khmer Land" in Khmer writing, a local expression which refers to Cambodia
Preahreachanachâk Kampuchea means "Kingdom of Cambodia". Etymologically, its components are: Preah- ("sacred"); -reach- ("king, royal, realm", from Sanskrit); -ana- (from Pāli āṇā, "authority, command, power", itself from Sanskrit ājñā, same meaning) -châk (from Sanskrit chakra, meaning "wheel", a symbol of power and rule).
The name used on formal occasions, such as political speeches and news programs, is Prâteh Kampuchea (Khmer), literally "the Country of Cambodia". Prateh is a formal word meaning "country." The colloquial name most used by Khmer people, is Srok Khmae (Khmer), literally "the Khmer Land". Srok is a Mon-Khmer word roughly equal to prâteh, but less formal. Khmer is spelled with a final "r" in the Khmer alphabet, but the word-final "r" phoneme disappeared from most dialects of Khmer in the 19th century and is not pronounced in the contemporary speech of the standard dialect.
