One of the Prose styles of the contemporary world is focused on the reflection of the outer world on the world of the story. This is widely used in the works of realist and naturalist Iranian writers. Sadegh Chubak, one of the prominent contemporary writers, has achieved a unique language by presenting the reality in his artistic prose. The aim of this research is to analyze the process of creating the meaning of reality in paradigmatic and syntagmatic axes. By an analytical-critical method and with the help of relevant theoreticians in this field, the author has analyzed Chubak’s realist-naturalist prose to highlight the features of naturalism in his prose as an artistic style of writing. It is concluded that Chubak’s writing is artistic and is far and beyond the hackneyed referential prose styles usually associated with naturalism.
