When referring to two writing systems coexisting for a single language, the term digraphia is used. In cases of three dialects, the term triglossia is used. In most cases, the H variety has no native speakers but various degrees of fluency of the low speakers. In addition to the community's everyday or vernacular language variety (labeled "L" or "low" variety), a second, highly codified lect (labeled "H" or "high") is used in certain situations such as literature, formal education, or other specific settings, but not used normally for ordinary conversation. In linguistics, diglossia ( / d aɪ ˈ ɡ l ɒ s i ə, d aɪ ˈ ɡ l ɔː s i ə/) is a situation in which two dialects or languages are used (in fairly strict compartmentalization) by a single language community.
