Czech is a West Slavic language with about 12 million native speakers; it is the majority language in the Czech Republic and spoken by Czechs worldwide. The language was known as Bohemian in English until the late 19th century. Czech is similar to and mutually intelligible with Slovak, the Sorbian languages and, to a lesser extent, with other Slavic languages.

Czech is widely spoken by most inhabitants of the Czech Republic. As given by appropriate laws, courts and authorities can enact and write out documents and judgements in the Czech language (also, financial authorities in the Slovak language). Czech can also be used in all official proceedings in Slovakia as granted by Article 6 of Slovak Minority Language Act 184/1999 Zb.
