Slovio is a newly-constructed language created by linguist Mark Hučko. It is an international auxiliary language primarily created to help Slavic speakers communicate. The grammar of Slovio is similar to Esperanto, but the vocabulary is derived from the most common words from Slavic languages, that of the largest European-language group.
The name of the language, Slovio, comes from the old-Slavic word "slovo" which means "word".
