 Roger Lass describes White South African English as a system of three sub-varieties spoken primarily by White South Africans, called "The Great Trichotomy" (a term first used to categorise Australian English varieties and subsequently applied to South African English).In this classification, the "Cultivated" variety closely approximates England's standard Received Pronunciation and is associated with the upper class; the "General" variety is a social indicator of the middle class and is the common tongue; and the "Broad" variety is most associated with the working class, low socioeconomic status, and little education.These three sub-varieties have also been called "Conservative SAE", "Respectable SAE", and "Extreme SAE", respectively.
