the coexistence of two closely related native languages or dialects among a certain population, one of which is regarded to be more prestigious than the other; also, that of two unrelated languages
The existence of "high" (formal) and "low" (informal, familial) dialects of a single language, such as German
Coexistence of two varieties of the same language in a speech community, with each variety being more or less standardized and occupying a distinct sociolinguistic niche. Typically, one variety is more formal or prestigious while the other is more suited to informal conversation or is taken as a mark of lower social status or less education. Classic diglossic situations can be found in Arabic-speaking communities, where Modern Standard Arabic coexists with dozens of regional Arabic dialects, and among speakers of Dravidian languages such as Tamil, where different words for basic concepts such as "house" or "water" are chosen depending on the speaker's caste or religion
