A number of diacritical signs were used until 1982, when they were officially dropped from Greek spelling as no longer corresponding to the modern pronunciation of the language. Monotonic orthography is today used in official usage, in schools and for most purposes of everyday writing in Greece. Polytonic orthography, besides being used for older varieties of Greek, is still used in book printing, especially for academic and belletristic purposes, and in everyday use by some conservative writers and elderly people. The Greek Orthodox Church continues to use polytonic and the late Christodoulos of Athens and the Holy Synod of the Church of Greece have requested the reintroduction of polytonic as the official script.
