Interslavic

Interslavic (Medžuslovjansky / Меджусловјанскы) is a pan-Slavic auxiliary language. Its purpose is to facilitate communication between speakers of various Slavic languages, as well as to allow people who do not speak a Slavic language to communicate with Slavic speakers by being mutually intelligible with most, if not all, Slavic languages. For Slavs and non-Slavs, it can be used for educational purposes as well.

Interslavic can be classified as a semi-constructed language. It is essentially a modern continuation of Old Church Slavonic, but also draws on the various improvised language forms Slavs have been using for centuries to communicate with Slavs of other nationalities, for example in multi-Slavic environments and on the Internet, providing them with a scientific base. Thus, both grammar and vocabulary are based on common elements between the Slavic languages. Its main focus lies on instant intelligibility rather than easy learning, a balance typical for naturalistic (as opposed to schematic) languages.

The Interslavic project began in 2006 under the name Slovianski. In 2011, Slovianski underwent a thorough reform and merged with two other projects, with the result called "Interslavic", a name that was first proposed by the Czech Ignác Hošek in 1908.

As with the languages of the Slavic language family, Interslavic is generally written using either Latin or Cyrillic letters, or on rare occasions the Glagolitic script.
