The article draws attention to the problems associated with modeling of word formation system of the Polish language in the synchronous description. The author is primarily interested in the consequences of entanglement of the subject matter of word-formation between the two points of view – synchronic and diachronic, and connected with this fact diffi culties in combination of formal and semantic plane in the description of derivatives and the gap between the research and lexical word-formation. Referring to I. Bobrowski who states that the language system and the language model are two different entities, the author presents the assumptions on which she proposes to build a model system of word formation, referring to the concept of A. Bogusławski.
