The same name (i.e. Kamboj/Kambuja) is also found in Burmese and Thai chronicles referring to regions within those kingdoms.
An origin-myth recorded in the Baksei Chamkrong inscription, dated AD 947, derives Kambuja from Svayambhuva Kamboj, a legendary Indian sage under whose gotra later, the merchant Kaundinya I reached the Indochinese peninsula and married a Nāga princess named Soma, thus uniting the Indian and local Southeast Asian Funanese cultures.
Etymologically, its components are: preăh ("sacred"); réach- ("king, royal, realm", from Sanskrit); -éana- (from Pāli āṇā, "authority, command, power"); -châkr (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 ប្រទេសកម្ពុជា Prâtés Kâmpŭchéa [prɑteːh kampuciə], literally "the Country of Cambodia".
srŏk is a Mon-Khmer word roughly equal to the Sanskritic Prâtés, but less formal.
