Czech language [SEP] Introduction
Czech (; Czech ), historically also Bohemian (; "lingua Bohemica" in Latin), is a West Slavic language of the Czech–Slovak group. Spoken by over 10 million people, it serves as the official language of the Czech Republic. Czech is closely related to Slovak, to the point of mutual intelligibility to a very high degree, as well as Polish. Like other Slavic languages, Czech is a fusional language with a rich system of morphology and relatively flexible word order. Its vocabulary has been extensively influenced by Latin and German. The Czech–Slovak group developed within West Slavic in the high medieval period, and the standardization of Czech and Slovak within the Czech–Slovak dialect continuum emerged in the early modern period.
