What is a periodic sentence?

A periodic sentence is a sentence that is not grammatically complete until the end. It is often structured with the main clause at the end, after a series of introductory phrases or clauses. This type of sentence creates suspense and anticipation for the reader, as they must wait for the main idea to be revealed. Periodic sentences are often used in literature and speeches to create a sense of drama and emphasis. Famous examples of periodic sentences include: "In the meantime, the butcher had been arrested with the knife in his hand." (Charles Dickens, "A Tale of Two Cities") and "In the darkness, the two figures shone, their faces illuminated by the flickering light of the candle."
