The official name of the country in English is the Kingdom of Cambodia, translated from the Khmer Preăh Réachéanachâk Kâmpŭchéa, often shortened to just Kampuchea (Khmer: កម្ពុជា). Kampuchea derives from the Sanskrit word Kambuja. Colloquially, Cambodians most often refer to their country as ស្រុកខ្មែរ (Khmer pronunciation: [srok kʰmae], Srok Khmer), meaning "The Land of the Khmers" or by using the slightly more formal formប្រទេសកម្ពុជា (Khmer pronunciation: [prɑteːh kampuciə], Prateh Kampuchea), literally "The Country of Cambodia". The English form "Cambodia" is derived from "Cambodge"/"Kamboj", the Sanskrit transcription of "Kampuchea".
