In Republic of Moldova the socio-linguistic picture is equally simple and complicated: it’s simple because this territory frames one historic language – Romanian language, with the right to be officially declared; it’s complicated because other languages, of ethnic minorities long for this right too, even though they have no social-politic base for this. All ethnic minorities languages (Russian, Bulgarian, Gagauzian, etc.) have their historic motherland. That’s why the declaration of these would undermine our state. These thoughts we try to evolve in the following article: Neither the diglossia, nor the bilingualism can be accepted in Republic of Moldova.
