Czech (/ˈtʃɛk/; čeština Czech pronunciation: [ˈt͡ʃɛʃcɪna]), formerly known as Bohemian (/boʊˈhiːmiən, bə-/; lingua Bohemica in Latin), is a West Slavic language strongly influenced by Latin and German language, spoken by over 10 million people and it is the official language of the Czech Republic. Czech's closest relative is Slovak, with which it is mutually intelligible. It is closely related to other West Slavic languages, such as Silesian and Polish. Although most Czech vocabulary is based on shared roots with Slavic, Romance, and Germanic languages, many loanwords (most associated with high culture) have been adopted in recent years.
