Mitologizmy grecko-rzymskie w retrokryminałach Marka Krajewskiego – konwencja i inwencja w aspekcie funkcjonalnym

The subject to be presented and described in the present paper are word combinations with mythological (Graeco-Roman) origins occurring in eight crime novels penned by Marek Krajewski, taking the shape of: (i) better or less known phrasemes, or conventional petrified multiword units reproduced in a communicative act to express particular intentions and intensions; (ii) phrasematic innovations, or phrasemes modified formally and/or semantically and used against the grain of the phraseological norm; or (iii) literary nonce phrasemes, that is multiword units created ad hoc for the purposes of style and world depiction, containing eponyms and eponymisms of mythological origin which exist in Polish. The proposed examination of conventional (the titular convention), innovative, and nonce (the titular invention) units used in the excerpted crime novels is of a qualitative and functional nature, since its focus is on an attempt to point out and discuss the functions which the selected examples serve in the literary messaging. Polyword mythology-based expressions fulfil numerous and various (often at the same time) functions in M. Krajewski’s crime novels, incl. cultural-identitarian, content-focused, expressive, evaluative, aesthetic and others.
