Explain about theree criteria of diglossia?

Answer 1

I'm not quite sure whether you were after three clear criteria for diglossia or whether you were in fact after the criteria for diglossia, however, here is a brief start on an answer:

Diglossia occurs when you have two distinct forms of the same language, a high variety and a low variety. It needs to be distinguished from bilingualism (knowledge of two languages). Each of the varieties of the language has a different function and these functions are distinct. For example when talking to people close to you you would use the Low variety of the language, but in more formal situations (say for a religious service) you would use the high variety. There is generally prestige associated with the use of the High variety. Usually the literary heritage of the speech community is preserved in the High variety as well.

There are a range of European and Asian languages that find themselves faced with the issues surrounding diglossia, Arabic, Indian and Javanese are some examples.

Answer 2

Three criteria of diglossia include the coexistence of two distinct language varieties within a speech community, each with separate functions and social prestige. These varieties are used in different social situations or domains, such as formal versus informal contexts. There is also a clear division of labor between the high (H) and low (L) varieties, with H typically used for literature, education, and formal occasions, while L is used for everyday communication.
