Czech is a language used by the European Union, which is spoken by approximately 12 million people, and is a member of the West Slavic language group. This language shares a great deal in common with other West Slavic languages, including Slovak and Polish. Oftentimes, an individual who speaks Polish can understand a Czech speaker, and vice versa. This language's relationship to its native speakers, as is the case in much of Eastern Europe, is very much one concerned with their sense of national identity. The language is used as an official language in the Czech Republic and is spoken is several other nations, as well. Austria, Serbia, Slovakia and Croatia all have populations that speak Czech as a minority native tongue.
Eastern Europe in general, since the fall of communism as the dominant economic model, has been very receptive to international business. These emerging markets are full of people who speak English as a second language. The language can be easily written on the web, having a Latin alphabet with some accent marks added above certain letters. While this language can be understood to a functional degree by speakers of some other Western Slavic languages, it does have its own particular linguistic characteristics that set it apart. Professional translation can open up this market and, largely, the Slovak market with which the Czech people are so culturally and historically connected. Any legal or official documents in the Czech Republic, including financial transactions, will be written in Czech.
