Where there is a strong divergence, the language is said to exhibit diglossia.
Arabic is a clear case of diglossia.
Diglossia is associated with another complication.
Diglossia alludes to a historical process that involves consideration of at least two languages in conflict.
Coulmas questions whether a genetic relationship between languages is a requirement for diglossia.
Fishman (1967) refines thinking on diglossia by noting that diglossia could develop with or without widespread bilingualism in a community.
