This country currently only has two languages in common use: Language A, spoken by 62% of the population, and language B, spoken by 38%. Both languages have official status in the country, so road signs, government documents, education, business, etc are conducted and printed in both languages. However, tensions have been increasing between the two groups that speak each language. Also, this is a developing country that does not have a large economy, as the global market is dominated by language C that is different from both of these.
To prevent a civil war between the two opposing sides AND modernize the country's economy, the government proposes a solution: it employs a team of highly specialized linguists to construct a hybrid language that incorporates vocabulary, spelling, grammar, and pronunciation from all three of these languages. This hybrid language, Language D, is acts as kind of a compromise between A and B, but is also close enough to C to be understood by a foreign speaker of C.
Language A and B were the same until 1000 years ago. Language C was the same as A and B until 1500 years ago. All three are written with the same alphabet.
With all of that in mind, I now ask you three questions:
- Could language D actually be created?
- How could the government enforce the use of language D? Through force (using the old language means death), semi-force (using the old languages in public, education, media, and business is banned; heavy fine if you disobey), or through passive force (official language is D, and it is used in government, business, and education, it is recommended that you learn language D)?
- Would language D actually have the capability to prevent a civil war and modernize the economy?
Edit: This a fourth question I just added after reading a lot of the answers:
- Would it just be better to use language C rather than create the hybrid language D? Cheers!
