This wordlist has been modelled on P. M. Roget's »Thesaurus of English Words and Phrases». This kind of wordlist can be seen as a synonym dictionary of sorts. But each conceptual class comprises not only synonyms, but words of all kinds which are habitually used in discoursing on the kind of topics which could be subsumed under the class label concept, understood in a wide sense.
Regarding Roget's classification system, there are arguably a number of classes which ought to be merged or split. But this classification seems to have established itself solidly through many editions of Roget's work as well as German copies of it. It should also be considered an advantage that the same classification is used in such dictionaries for different languages.
