Dimotiki in the context of "Katharevousa"

Modern Greek (endonym: Νέα Ελληνικά, Néa Elliniká [ˈne.a eliniˈka] or Κοινή Νεοελληνική Γλώσσα, Kiní Neoellinikí Glóssa), generally referred to by speakers simply as Greek (Ελληνικά, Elliniká), refers collectively to the dialects of the Greek language spoken in the modern era, including the official standardized form of the language sometimes referred to as Standard Modern Greek. The end of the Medieval Greek period and the beginning of Modern Greek is often symbolically assigned to the fall of the Byzantine Empire in 1453, even though that date marks no clear linguistic boundary and many characteristic features of the modern language arose centuries earlier, having begun around the fourth century AD.

During most of the Modern Greek period, the language existed in a situation of diglossia, with regional spoken dialects existing side by side with learned, more archaic written forms, as with the vernacular and learned varieties (Dimotiki and Katharevousa) that co-existed in Greece throughout much of the 19th and 20th centuries.

The linguistic varieties of Modern Greek can be classified along two principal dimensions. First, there is a long tradition of sociolectal variation between the natural, popular spoken language on the one hand and archaizing, learned written forms on the other. Second, there is regional variation between dialects. The competition between the popular and the learned registers (see Diglossia) culminated in the struggle between Dimotiki and Katharevousa during the 19th and 20th centuries. As for regional dialects, variation within the bulk of dialects of present-day Greece is not particularly strong, except for a number of outlying, highly divergent dialects spoken by isolated communities.
