V prispevku je predstavljen pregled rabe pojmov dekadenca in dekadentnost v besedilih različnih tipov nastalih v slovenščini v letih 1897-2007, v katerih prevladujejo različne funkcijske zvrsti. Avtorica analizira semantični status omenjenih pojmov glede na stopnjo objektivnosti in ustaljenosti. Na podlagi kategorizacije, ki jo je uvedel Janusz Sławiński, loči termine-poimenovanja, teoretske termine in kvazipoimenovanja. The paper presents an overview of uses of terms decadence and decadency in various types of texts written in Slovene in the period between 1897-2007, dominated by various functional text types. The author considers the semantic statuses of these terms in respect to their level of objectivity and constancy. The analysis is based on the categorisation introduced by Janusz Sławiński, who differentiates between terms-names, theoretical terms and quasi-names.
