| In a diglossic situation, some topics and situations are better suited to the use of one language over another. |
| Over the past fifty years Tamil literature has expanded from the almost exclusive use of the high diglossic level, traditionally used in writing, to include spoken Tamil. |
| But in general, all these languages are in an indisputably and strongly diglossic situation. |
| Quinn first questions the academic argument, which he sees as ignoring the importance of separate diglossic language communities as a basis for maintaining an ongoing bilingualism. |
| Outcomes may also be affected by the type of bilingual programmes evaluated and whether there is a diglossic language environment, in which different languages are used for different functions and situations. |
| Thus, the patterns of language usage and existence of diglossic language communities, which are necessary to the survival of individual languages, may be absent or weak. |
