What is "diglossia"?


assistant
Diglossia is when one community uses two different languages or dialects depending on the circumstances e.g. for written things and for casual conversation. A weird (not actual schoolbook) case of that is Swiss German. High German is used for written and formal things while Swiss German is used to speak.
