Features

The Slavic languages are a relatively homogeneous family, compared with other families of Indo-European languages (e.g. Germanic, Romance, and Indo-Iranian). As late as the 10th century AD, the entire Slavic-speaking area still functioned as a single, dialectally differentiated language, termed Common Slavic. Compared with most other Indo-European languages, the Slavic languages are quite conservative, particularly in terms of morphology (the means of inflecting nouns and verbs to indicate grammatical differences). Most Slavic languages have a rich, fusional morphology that conserves much of the inflectional morphology of Proto-Indo-European. The vocabulary of the Slavic languages is also of Indo-European origin. Many of its elements, which do not find exact matches in the ancient Indo-European languages, are associated with the Balto-Slavic community.
