Abstract:(Lexical and semantic geometrizations in Mircea Cărtărescu's novel Solenoid) The present work, entitled Lexical and semantic geometrizations in Mircea Cărtărescu's novel Solenoid, is part of a series of studies that I have dedicated, in recent years, to the language used by the Romanian writer in his novels. Excerpted from various fields (medicine, physics, chemistry, mathematics, philosophy, botany, psychology, etc.), the lexis reveals the mental architecture or system of a complex thought, indicates and justifies a certain level of knowledge, or establishes, with an original syntagma favored by the author, the „cenotaph of language”. Between the dominant lexis of hypernyms and the universe of all adjacent lexical units, derived from the former, inescapable and sophisticated semantic networks can be observed in light of specific analyses. These imply extensive lexical and semantic geometrizations, worthy of being transferred towards the other works of this 1980s novelist, a likely Nobel candidate. The textual synapses, the nervature of the phrasing, and the anatomy of the entire novelistic structure, all the details that stand out, nuances of a conceptual scaffolding, testify of the commitment and vastness of his literary undertaking. Cărtărescu's lexis, and not only that of the novel Solenoid, organizes itself into formations, like a living organism. The labyrinth of thought has as its reflex the textual gear. Following the principle of Russian dolls or fractal reduplication, the employed lexis reveals the subsidiary presence of mathematical formulas for capturing meaning. The corpus examined in this paper comprises approximately fifty units belonging to the neological register, primarily referring to the category of loanwords from the French language. Cărtărescu's style, eminently literary, flamboyant, and infused with visionary fervor, is meant to overcome the comfort of monotonous readings, to reshape the concept of novel and, by extension, of literature.
