Khmer names are names used in, or originating in, Cambodia which usually consist of two elements including a patronymic, which serves as a common family name for siblings, followed by a given name. Surname then given name (Eastern name order). An example is famous singer Sin Sisamouth, his surname (last name) is Sin and his given name (first name) is Sisamouth. (In Western sources, the two are sometimes reversed.) Traditionally, the Khmer do not have Western-style family names shared by multiple generations or entire families. Instead, Khmer children use their father's given name as their family name. Other Austroasiatic indigenous people groups within Cambodia have similar naming customs, while the Sino-Khmer and Viet-Khmer may follow Chinese and Vietnamese naming patterns, respectively.
