The official name of the country in English is the Kingdom of Cambodia and in Khmer as "ព្រះរាជាណាចក្រកម្ពុជា", often shortened to just Kampuchea. Kampuchea derives from the Sanskrit word Kambuja or "Golden Land" or "Land of Peace and Prosperity", as described by the Khmer Buddhist monk Chuon Nath in his Khmer Dictionary.
Colloquially, Cambodians refer to as ស្រុកខ្មែរ, meaning "Khmer's Land" or more formally as ប្រទេសកម្ពុជា, literally "Country of Kampuchea". Kampuchea is commonly known as "Cambodia" in English and "Cambodge"/"Kamboj" in French. Kampuchea is more widely known to Easterners and Cambodia is more widely known to Westerners. The word Khmer could indicate the country, its people or its language.
