Sažetak The study focuses on Czech emigrants leaving their home country for the USA from the half of the 19th century, and on the consequences of the new intercultural situation which they faced in the USA, namely its impact on their lives and language. These facts are being observed through analyses of Czech-American press, reason being that émigré journalism reflects all the relevant changes occurring in the lives of immigrants. The study concentrates on the 1860s and 1870s because it is in this period that interculturality is most apparent in the lives of the Czechs in the USA. The author analyses both the content and the language of the periodicals. Attention is paid to ethno-methodological conversation analysis, namely the transformation of social categories which the immigrants endorsed in relation to their ethnicity. Special attention is also being paid to the Americanization of the Czech language in its early phase.
