“ In every school the teacher makes daily use of repetition in her efforts to explain to the pupils that which they do not understand. In a similar way a writer makes use of this tendency of ours, and develops the idea of the topic sentence by repetition. Each sentence should, however, do more than merely repeat. It should add something to the central idea, making this idea clearer, more definite, or more emphatic. If repetition is excessive and purposeless, it becomes a fault.Repetition may extend through the whole paragraph, or it may be used to explain any sentence or any part of a sentence. ”
