 Koiné language

In linguistics, a koiné language, koiné dialect, or simply koiné (Ancient Greek κοινή, "common [language]") is a standard or common language or dialect that has arisen to prestige or dominance as a result of the contact, mixing, and often simplifying of two or more mutually intelligible varieties of the same language.As speakers already understood one another from before the advent of the koiné, the "koineization" process is not as drastic as pidginization and creolization.
