Among other traits which set Caragiale apart from his fellow Romanian writers was his highly creative vocabulary, partly reliant on archaisms and words occurring rarely in the modern Romanian lexis (including ones borrowed from Turkish and Greek, or even from Romani). In certain cases, he used an inventive spelling—for example, he consistently rendered the word for "charm", "farmec", as "fermec". Tudor Vianu noted that this habit was similar to experiments presents in Ion Barbu's cryptic poetry, ascribing both cases to "the intent of underlining the differentiation between the written and the spoken words", while Ion Vianu defined Caragiale as "an accurate artisan of the language, an extraordinary connaisseur of the Romanian language, which, out of snobbery, he sets aside for the plebeian readers." "Craii de Curtea-Veche" introduces a large array of words present in early 20th century slang and Romanian profanity, as well as rendering the then-common habit of borrowing whole sentences from French to express oneself (a trait notably present in Mateiu Cargiale's own day-to-day vocabulary). The novel's tone, often irreverent, and the book's foray into the mundane have been seem by some as tributary to the informal style cultivated by Bogdan-Pitești.
