The Czech language is the official language of a country.
=== Common Czech ===The main Czech vernacular, spoken primarily in Bohemia including the capital Prague, is known as Common Czech (obecn etina)
 In practice, however, word order is flexible and used to distinguish topic and focus, with the topic or theme (known referents) preceding the focus or rheme (new information) in a sentence; Czech has therefore been described as a topic-prominent language
