Description	Common morphological analysers offer lemmatization, but they do not have an information (or only to a little extent) on derived words. Such information can be very helpful for indexing texts for searching or for a syntactical analysis of the natural language. Our Czech Derivational Analyser is a fast tool which offers an information on derivational relations between words. The analyser is available in the form of a command line tool or as a library in the form of calling functions in the C++ language. The analyser is based on finite automata and partially uses Jan Daciuk's algorithms for creating minimal finite states automata, so that it is both fast and easily maintainable. On the present, we have data only for Czech, but the tool itself can be used for other languages as well.
