Foucault's concept describes how discourses delimit possible statements. In poetry, discursive formations influence themes, style, and permissible expression. A poem can both reflect and resist dominant discourses, revealing their constructed nature. By working within and against these formations, poets contribute to cultural change, challenging norms and opening new avenues for thought through the subtle power of poetic language.

Discursive formation, a concept from Michel Foucault, refers to a system of statements, practices, and institutions that work together to produce knowledge, define truth, and shape subjects within a particular historical period. A discursive formation governs what can be said, who is authorized to speak, and what counts as meaningful discourse. It is not just a set of ideas but a material and institutional network. In poetry, discursive formations influence the themes, language, and forms that are considered valid or important. A poet can work within a dominant discursive formation, reinforcing its norms, or they can resist and subvert it, revealing its constructed nature and opening new spaces for thought. For example, the discursive formation of Romanticism valorized nature and the individual, while the formation of Modernism was skeptical and fragmented. Understanding this term helps poets locate their work within a larger historical and cultural context.
