The subject of the description provided in the article is word formation activeness of the pronoun 'SAM' ( 'alone', '(by) oneself', 'only', 'mere' and 'very') in contemporary Polish. The analysis of the derivational nest of the pronoun 'SAM' constitutes a point of departure for the dissertation. The author proves that this pronoun has a minimum derivational potency, which has to be enhanced by connecting another root words from beyond the nest. Thus, compound formations significantly outnumber non-compound motivated words of the first derivational tact. He analyses the differences between the word formation activeness of compound nouns and adjectives of the first tact. The former create mainly nouns by multiplication of the same derivational models (this is the phenomenon of quantitative word formation activeness), the latter produce less derivates, which are however more diverse (qualitative activeness) and represent all parts of speech beside the verb whose lack is pointed as a distinctive feature of the nest of the pronoun 'SAM'. Moreover, the author presents the derivational graph of the pronoun on which he marks quantitative and qualitative centers of pronoun derivation.
