In multilingual societies, language use is often complex and dynamic, involving phenomena such as diglossia, bilingualism, code-switching, and code-mixing. For instance, a society may be both diglossic and bilingual, but how do speakers decide which language or variety to use in different situations? Is this choice influenced more by context, identity, or social status? Moreover, many bilingual speakers use code-switching and code-mixing in their daily conversations, but does this reflect linguistic competence or a lack of vocabulary? With the impact of globalization, these practices are becoming more common, especially among young people, which raises another question: is this trend enriching languages or threatening their purity? Finally, can language planning policies really control such natural linguistic behaviors, or do speakers ultimately shape the future of their languages?
1/Can a society be both diglossic and bilingual at the same time? How do they interact?
2/Can a creole language become a standard or official language in a country?
3/Can code-switching and code-mixing be considered a natural result of bilingualism and globalization?
