Greece is one of six countries in this database that does not legally have an official language, only a ‘de facto’ one: Greek. This is partly because the Greek Constitution avoided a direct declaration of “Greek” so as to not have to choose between two Greek varieties: Dimotiki, the spoken vernacular variety, and Katharevousa, the purified archaic variety. This “Greek Language Question” was debated over the course of decades and only resolved in 1976 when Dimotiki was finally established the official variety for education on all levels – although the law itself (Law 309, Article 2; enacted on April 30, 1976) was written in Katharevousa and only made reference to ‘Modern Greek’. Since 1951, official Greek censuses no longer count the number of minority languages speakers. Greece has not signed the European Charter for Regional and Minority Languages (ECRML), and has only signed (but not ratified / enforced) the Framework Convention for the Protection of National Minorities (FCNM). There is also no official national data on the number of Sign Language users in Greece; the number of deaf Sign Language users is estimated to be around 300 000. In some regions, the usage of sign language was historically stigmatised (see link below), although this situation has improved over time. At least according to one source (linked below), a conference at the University of Thessaly claimed in the course of International Mother Tongue Day, that around 800 languages are spoken in Greece, not counting dialects – which would be, they postulate, 1/10 of all languages in the world.
