The article informs about a new monograph 'Kompozice v kontextu soucasne cestiny' (Composition in the context of contemporary Czech) - Mitter (2006) which deals with the role of composition in the contemporary Czech language. This theme is attractive for several reasons, of which the most significant are: increase of composition as a word-formation process in Slavonic languages; insufficient attention paid to this issue (in Czech as well in Slovak linguistics); and last but not least, it brings several possibilities to compare the dynamism of Czech and Slovak wordstocks. Mitter's complex analysis raises questions as well, concerning: e.g. onomasiological status of compounds, word-formation motivation, formal structure, relation between form and (word-formation) meaning.
